Been off the mainland all week. I designed a new mold (series of molds)
on my laptop the first day, but after that I did vacation things.


I saw Jim and Richard talking about post apocalyptic retribution, but I
wasn't interested enough to setup Usenet on the mail client on my laptop.

I'll just say this. Some of the former Royal Marines who have worked
with and trained with US forces have a much higher estimation of US
military capability than Richard seems to. One such claimed on YouTube
seems to think the US could hold their own against the rest of the
world. I don't think that's true, but I do think it might take the
whole world or nearly the whole world to take us down. Conquering the
US mainland for occupation would require nuclear annihilation. Because
of the size of the USA it might still be a challenge. We would have the
best armed partisan forces in the history of the world. Literally "an American with a rifle behind every blade of grass" (quote - not mine),
and atleast one jack of all trades capable of bringing ideas to life in
every town, borough, and village. Even the smallest little communities
so small they aren't even incorporated (or draw the attention of direct bombing hits) has somebody who can "fix things" if its worth it.

Don't count on much here. As I near 80 rotating the tires has become a

You don't have to do much. Just tell the youngster doing the work.

Connect the load cell here. Connect the magnetometer here. Mercury and mechanical tamper switches go in last, and the last thing you connect is
the latching circuit, and no matter what you do don't flip the power
switch until you are sure it where you want it and it won't move.

If I keep lifting and heaving (within old man limits) I may put off the time when I become 'normal' (average). I upgraded AAA to the 100 mile tow etc,
and saved more on my insurance by dropping its 25 mile tow.

A 1/2" Magnum Holeshooter has much more torque to spin the scissors jack
than my cordless Dewalt. I suppose I only have to prove that the tools I
carry in the car are adequate once. As usual the jack to drill chuck adapter was shop made.

A used Bronco Sport I examined had a non-original full sized spare in the well. That's rare. What's less rare is snowstorms during my holiday trips
out of state, when I DON'T want mismatched tires that brake differently.

The larger Bronco (not Sport) can have a 4WD Auto mode that allows driving
on mixed dry and icy pavement, like limited-slip AWD, in addition to the regular 4WD that locks the axles together like my Ranger. The Net hasn't
been helpful with details. Does anyone have experience?

When I bought the Ranger they told me a woman had kept hers in 4WD on
pavement and destroyed the drive train in 20,000 miles. Mine lasted in 2WD until slightly after the warranty ran out, when the lubed-for-life U joints ran out of lube, and life. The replacements have grease fittings and are
fine at over 150,000.

Much of the custom equipment I built was intensively but not extensively complex or physically large, a one man job. When a project was big enough to need several assemblers the documentation usually broke it down to match,
such as assembling and wiring a control box after all the individually numbered wires had been run into it. This was before DIN rail when the relay sockets etc had to be individually bolted to the back plate and the wires terminated with crimp lugs. Doing everything myself saved enormously in documentation, test and debugging time. Perhaps quick delivery was why the small NH company won a large share of the GM and Chrysler automotive electronics test station business. Only Ford designed their own, in-house.

We have an outbreak of a type not included in the yearly shot, H3N2 sub K. I've been wearing an N95 mask and gargling with prescription Chlorhexidine Gluconate left from dental implant surgery.

The worst I caught was RSV before the vaccine came out, my throat was so

My simple intuitive take: The intake transforms high air velocity into low velocity pressure (like a sail), which pushes outward against the walls, forward against the diffuser and rearward against the flame, which can
resist the inlet pressure through inertia because it increases the mass
(added fuel) and velocity (high temperature) of the exiting exhaust gas.

The unbalanced pressure against engine metal in front but against only hot
gas behind is thrust, like the recoil of a gun where the forward pressure
acts only on the freely exiting bullet.

Per Newton, F=MA. F is from the combustion chamber pressure, MA from the expanding exhaust.

The recoil force of a garden hose nozzle is from a similar unbalanced
pressure and acceleration. The recoil is much less without the nozzle though the volume flow rate may be greater.

A nuclear reactor creates exhaust pressure by increasing only the
temperature to accelerate the air, similar to the added thrust from the Mustang or Spitfire radiator. Hydrocarbon fuel also increases the mass and
its hydrogen doubles the oxygen to water vapor volume. C + O2 -> CO2, 4H +
O2 -> 2 H2O.

I read a General's leadership lesson on how some people respond to reason (Khrushchev, actually), others only to threats (Putin). Trump learned the effective degrees of their use in the combat arena of NYC real estate, as
well as that a good deal satisfies both parties. Clearly his loudest critics misrepresent or just don't understand at all what he's doing. They are so surprised when he succeeds where no Democrat had gone before.

Being an easily angered A-hole is the standard New York defense mechanism, down to the lowest store clerk or waiter. I had to learn it wasn't personal and to ignore it.

Khrushchev saw that JFK was hopelessly struggling and offered a secret way
out of the Cuban Missile Crisis that traded removing his missiles from Cuba for ours from Turkey. The missiles had been Guevara's idea and as part of
the deal Castro shipped him off to lead irrelevant rebellions in Angola and Bolivia.

------------------------------------ https://www.nuclear-power.com/nuclear-engineering/fluid-dynamics/bernoullis-equation-bernoullis-principle/velocity-head/

Neglecting friction etc loss, the total energy of the air remains constant
as it slows down (relative to the engine), which means its velocity energy converts to pressure energy. This is similar to a pendulum bob alternating between speed and height.

The combustion chamber can't increase pressure because then air wouldn't
flow into it, but it can provide enough inertial resistance toward the rear
to maintain the pressure of the intake air. How to create pressure without equal drag is beyond my education. Wings easily produce more than ten times
as much lift as drag, more than 30 times for sailplanes. https://en.wikipedia.org/wiki/Lift-to-drag_ratio

This shows the pressure and temperature curves through a jet engine: https://www.researchgate.net/figure/Pressure-and-temperature-characteristics-through-a-GE-J79-turbojet-gas-turbine-Reprinted_fig1_321401512

A ramjet operates at speed high enough to not need the compressor turbine,
or the exhaust turbine that drives it and limits engine operating
temperature due to high centrifugal force trying to stretch the red to white hot blades.

ICBMs did not neutralize our advantage of widely distributed foreign bases because they served many functions unavailable to the USSR, importantly land based surveillance. This is an example of the USSR's struggle to match us
from within their own territory:
https://en.wikipedia.org/wiki/Duga_radar

Ten MegaWatts is far beyond satellite capability, even for the Soviet
nuclear reactor powered ones.
https://en.wikipedia.org/wiki/US-A
"..there were several failure incidents, some of which resulted in
radioactive material re-entering the Earth's atmosphere."

Somehow that escaped the attention of protesters.

May I run my "take" on it past you, testing it in every which way...?

From this ramjet engine with a nuclear power-plant in the middle heating
the air (no mass-rate, but is a heat-rate):

the exit/exhaust cone is bigger than the inlet cone - hence the sum of
forces is nett in the "progression" direction.

the reason the exit cone is bigger is that, keeping the same pressure
but now with thermal energy from the supplied heat (think gas laws,
models of bouncing/recoiling gas atoms/molecules, etc.)... To keep
fairly much the same pressure profile as the inlet cone the exhaust cone
has to be bigger in expanding the gas to a bigger volume - to get it
"down to the same pressure" (as the corresponding place in the inlet
cone).

I will go try read the article.

Sorry I am on the tail-end of a "winter 'lurghi'" (we have a 'lurghi'
season here in Britain where by February people often feel like daubing

Among the long German words I had to learn was spring fever's equivalent, Fruhjahrsmudigkeit.

That explanation makes sense to me, but much in fluid dynamics doesn't such
as L/D and the low drag of rounded leading edges, as on torpedoes and the
Mach 25 Space Shuttle. I especially don't trust extrapolating subsonic to supersonic shock wave flow in the ram jet intake. I still struggle with

My ability to accurately visualize physics doesn't approach that level.

As absurd as that may appear if you do not know how, government bonds and anticipated tax revenues are spendable money that doesn't actually exist
(yet) and my job was turning theoretical proposals into functional hardware.

For me the tangible return on money thrown into space was my home, vehicles and retirement accounts. The government can recirculate military and space spending back into the economy as a control mechanism that is independent of consumer supply and demand. Since our beginning Congress has ensured that
the money is distributed as widely as possible, with each district receiving
a fair share in exchange for support.

One tragic consequence was the Shuttle's rocket boosters being built in transportable jointed sections in Utah instead of a single piece in Florida.

Cabin fever is real. There used to be (maybe still is) a machinist get together called Cabin Fever where various hobbyists and on-line
machinist personalities would get together to break up that doldrum.
They would mostly perforate the poop, but there was also some horse
trading, and maybe a friendly competition or two. Never went myself.
Winter in SW Arizona is to nice to waste it visiting folks in snow
country, but they posted a few videos that looked like fun. Like seeing
who can dial in a part the fastest in a 4 jaw chuck. Stuff like that.
FYI: The one I watched Adam Booth was fastest on the 4 jaw.

Here it's temperate, but rains - often "mizzle" - somewhere between a
mist and a drizzle. Other times it is simply raining - and it can do it
for a long time - often on a 45deg or more slant as the winds rotate-in
from the West and South-West, from the lows out over the North Atlantic.

Vast amount of lighter stuff now stowed on boards in the roof-space,
managed to settle down with the paraffin stove radiating at me - and oh
yes it felt "good to be home". I used to mechanic motorcycles in the
garage at my folks' home as a youth - and was well set-up.
Here it comes again...
As I've mentioned - maybe I could get a lathe, a little milling machine
or shaper, ... Begin to make mechanical things...

Plans are coming as I sit there in the space and warmth...

Air-compressor up on a platform just under the roof (so it takes up no floor-space).
Iron pipe the length of the garden to the "hard-standing" area where I
could make lean-to's to cover mineral separation equipment.
Pneumatic single-head stamp for bashing-up sacks-full of ore? Just
flick the lever up and down and it's like a sledgehammer but neater and
more enclosed so bits don't go flying - what goes in all comes out the discharge... Air-hydraulic pump for useful rarely used hydraulic
things? - energy inefficient yes, but simple, totally reliable, just
stalls on overload, and can be left out but under cover.

Thoughts thoughts thoughts - big picture is it's a sign of optimism.

---------------------

I rebuilt old motorcycles too, made no money but learned a lot, such as I'm not a businessman. Reboring worn cylinders requires a larger milling machine than I have room for, I still need to send some larger work to a nearby
shop, which is also the source for cutoffs of steel in a size I don't have
and can do shearing and bending well beyond reasonable home shop capacity.

The 4" x 6" horizontal bandsaw I bought happened to be made well enough to clean up and align for square cuts, their reputation is often poor. I assume any decently priced used machine tool has something wrong the owner couldn't fix and am usually right, but I've diagnosed, understood and salvaged them. The exception has been estate sales.

My first small metal lathe has only a 4 jaw chuck and change gears for
thread cutting. While they make it slow to set up it still can do anything within its size and rigidity limits, which isn't saying much. The second lathe, all I could ask for, is a 1965 South Bend Heavy 10 with 5C collets
and a quick change gearbox. Its antiquated flat leather belt drive and threaded spindle mount have not been problems, actually they make some tasks easier, like stopping the cut right at the end of a thread by declutching
the belt and adding a spindle index dial behind the chuck to shave an
internal hex socket. The lathe was easily adapted to metric for laser
optics, and later making automotive special tools etc.

Neither lathe or my mill has dimension readouts beyond the handle dials and for one-off custom work to my own design or to repair worn parts I don't
need digital readouts. I take a rough cut, measure it, and move inward as needed. This compensates for worn leadscrews. The limit of accuracy is the measuring tool, not the old machine.

My compressor is also in a corner, but it has to be serviced in place.
In order to reduce vibration and noise I placed it on rubber pads cut
from old tire treads, and through bolted it to the concrete floor. One
thing I did before placement was put a street elbow the bottom in place
of the drain. Then a long nipple with a long handle ball valve on the
end. I open it everyday to blow out condensation accumulated in the
tank. On really buys days with lots of machines running I open it a few
times per day. I get some moisture in my prefilter still, but since
putting int he 75CFM Schultz dryer I haven't had any on the post filter.

Thank you, that is very good. I'm familiar with rebuilding the oil filled multiplate clutches on motorcycles.

My checklist includes AWD and a full sized spare, the last time I had a tire puncture repaired was this past Wednesday and I couldn't have found the tiny wire staple (?) beside the road, it took a lot of soapy water spray.

My 2000 CRV has a slippable AWD clutch activated by a difference in oil
flows from pumps driven at front and rear driveshaft speeds. It's a somewhat fussy system that noisily demands fluid changes every 25,000 miles, though with proper care old CRVs can last 300,000 miles. I'm at 86,000. The more I look at new vehicles the more I hope to keep the old ones going. Though not
as simple as cars used to be they are tolerable to repair and I have the
paper factory shop manuals which I can't get for a new one. Mine are taller and less aerodynamic, so the door is several inches higher and I don't have
to bend my creaky old neck to get in without hitting.

My 91 Ranger has an electric transfer case shift motor that's considered an expensive liability. The motor can shift (slowly) between 4WD hi and 2WD on the fly but the front hubs don't disconnect until driven backwards, and sometimes not then depending on how the hub grease feels about it. The
system is fine for logging and severe winter snowstorms but demands dirt
bike sliding reflexes when the roads are mostly dry with scattered ice patches.

I had a small part in the early development of ABS and share the
"reluctance" about the exposed magnetic wheel speed sensors that are also traction control inputs. https://www.mevotech.com/tips-practices/wheel-speed-sensors-and-contaminants/

All the sandpits where I used to play on a dirt bike are now shopping malls.
A tame SUV is still the right vehicle to go there. For me off the pavement
is an inch or two of ice above it.

My 1982 Chevy K10 came with those hubs and supposed shift on the fly.
Hardcore four-wheelers replaced them early on. Had a tendency to self
destruct when trying to rock your way out of being stuck...

I eventually replaced them with manual hubs too. Didn't trust them to
release and didn't want to mess around cleaning, re-lubing them. Spec
called for a special grease. A nice benefit was getting pseudo 2-Low.
Low range was really nice for climbing on ramps, moving trailers around
and just idling about without drive train wrap-up.

Replaced it with a used 2013 Chevy Impala. I try really hard to stay
off the roads when they're salted. Wait for them to be clear and less
salty before heading out...

Which manual hubs? https://www.ford-trucks.com/forums/703665-warn-vs-milemarker-hubs.html

I did my logging on the upland back side of the property and left the dead trees around the road and swamp for the owner to burn, so mud wasn't a
problem until I had cut everything dead within reach from the trails and switched to my small and narrower garden tractor and trailer that could go anywhere including problem areas the trails had avoided. There were small
rock piles showing where people had tried and abandoned hope of farming.

Staying off salted roads has been much easier since retirement. I'm finding and repairing the rust damage from commuting. The club postponed tonight's meeting due to the big snowstorm that has reached us.

I preferred a motorcycle for mountain camping trips and trail riding with
this club:
https://www.netra.org/
They are not the usual image of a large motorcycle gang, more Barbour jacket than black leather, Bultaco instead of Harley. I learned motorcycle snow and ice riding skills though I wasn't nearly competitive enough to race.

The Ranger has stock tires and the 2.3l 100HP engine, more than enough for slow congested commuting and capable of 28 MPG. The forest where I logged is now housing, the only rocky hill left to crawl is my back lot.

I try not to be the third, I held their beer and acted impressed while
friends did the "watch this". I was never in the driver's seat when the battery broke loose on landing and hit the fan.

"An estimated 300 cars were destroyed during the production process,..."

This seems a good place for:
https://en.wikipedia.org/wiki/JATO_Rocket_Car

An original participant posted the real story here on R.C.M. The junked car was unoccupied, going an estimated 60 MPH on ore cart bogies on mine
railroad tracks they had cleared of wind blown sand. After the crude
automatic braking failed it lodged in the mine tunnel entrance which then collapsed onto it. The spinning tire marks were from their pickup's hasty
exit from sand to asphalt.

It's a good example of misinterpreting incomplete evidence to support an assumed conclusion. Another is the Grassy Knoll theory where the loud bang
and mist cloud of a broken soda bottle has been taken as gunshot evidence, despite modern powder being completely smokeless. Zapruder's receptionist didn't mention the bottle breaking until 1966 and the interview was lost
until 1985.

Don't count on much here. As I near 80 rotating the tires has become a tiring task, mostly for getting down and up. I'm taking a break after
one side. Maybe I should invest in power tools instead of practicing roadside changes.

Local tire shop charged me 44 bucks to rotate and balance on the 'Yota
. He also charged me 40 bucks to clean up the rim and remount a tire for
my tractor - and earned every dime , that wheel was in horrible shape
when he started , rusty and nasty . Tips go in a lunch fund for the crew

As absurd as that may appear if you do not know how, government bonds
and anticipated tax revenues are spendable money that doesn't actually
exist (yet) and my job was turning theoretical proposals into functional hardware.

For me the tangible return on money thrown into space was my home,
vehicles and retirement accounts. The government can recirculate
military and space spending back into the economy as a control mechanism that is independent of consumer supply and demand. Since our beginning Congress has ensured that the money is distributed as widely as
possible, with each district receiving a fair share in exchange for
support.

One tragic consequence was the Shuttle's rocket boosters being built in transportable jointed sections in Utah instead of a single piece in
Florida.

That was only tragic because POLITICIANS demanded that launch take
place when it did . I still had contacts at Thiokol at that time and
they warned that those o-rings were too cold to obdurate properly to
seal the joint .

Have you tried boring a cylinder accurately with it?

My 1950's Clausing 8525 bores slightly tapered from wear that allows the
quill to deflect more from cutting force as it extends down. The later model has separate bolts for quill clearance and locking, on mine one bolt does both. It's better when boring by raising the knee.

The wear wasn't a concern until I reconditioned a hydraulic pump and tried
for minimal bearing clearance.

The RF-31 I ordered from MSC for the company shop wasn't quite square on any axis, and the tee slots weren't parallel to the travel. 0.005" was about the limit of its accuracy. It was adequate to replace a badly worn drill press, that's all. When I needed higher precision (rarely) I did the work at home
on overtime.

For gear cutting (precision anyway) an indexing head might be far better

I bought my machines before they became collectable. https://airgunwarriors.com/community/metal-shop/southbend-heavy-10-restoration/

I prefer the sculpted, almost organic aesthetic of its castings to the
squared billet chunkiness of modern lathes. The practical consequence is
that the carriage can overlap the head or tailstock to bring the tool very close to the spindle ends.

The only sporty vehicle from the 70's I have storage space for is my CB400F motorcycle. My BIL, a VW/Audi mechanic, restores old German and Italian
sports cars to showroom condition but it cost building a multi-bay barn with
a lift and paying its taxes.

I attend Cruisin' Nights and talk to the owners about what they did and
where they find parts and specialty skills. Most had the skill to write a
big check though one lady went into long credible detail about how she
rebuilt the engine. The cars are lovely but all that many can carry is passengers and maybe golf bags, I need serious capacity for heavy or long structural material, most recently 21' pipe lengths on the roof rack.

I have a 1980 Honda Accord in the garage, in use as a closet. I brought it
in to patch some rust holes, then found the lathe which the dealer unloaded behind it, locking it in until I or my flying pigs clear another space for
the lathe. It was the last car able to pass emissions without a catcon, due
to the lean burning CVCC engine.

Look how much these people are asking for similar ones. https://classiccars.com/listings/find/1980-1995/honda/accord

I bought a VW Beetle convertible at nearly giveaway price due to the
alarming loud noises from the engine area. Tightening the bumper bolts fixed that.

The time I've spent keeping my old car and truck on the road would have cost several times their value if I couldn't do the jobs myself. I was quoted
$3500 to fix the rust on one rear fender. Another shop quoted $800 just to weld the quarter-sized hole on other side, painting extra. My second hand
MIG welder cost less than half of that.

They evade questions about the machine shop work and electronic module troubleshooting. For the frozen 4mm distributor cap screw that broke the answer was don't bother, the two remaining screws will hold the cap well enough. I didn't ask about the stainless replacement captive screw I made on the lathe.

A custom shop told me that their estimate to restore a classic begins at $25,000. My body welding is detectable up close, "OK for an amateur", theirs isn't.

After solving the intermittent ignition problem on my pre-OBDII 91 Ranger
with an oscilloscope and the factory manuals I asked a dealer and a custom tuning shop about it. Both had gotten rid of their manuals and old test equipment, a mechanic had taken the dealer's home.

I've been watching a nearby Malibu to Chevelle SS conversion. Finding parts seems dependent on knowing who has the right wreck to plunder. At least the car is simple relative to new ones and his wife works for a welding
supplier. On 12/17 I peeked under a $70k Bronco and didn't understand half

Hello Snag, everyone

I haven't got any machine tool(s) yet.
What risked some serious problems was not getting things with my home
done. So put up a fence (and every learning thing that entailed -
complexity was when the fence was originally made the set the upright
timbers into the wall as it was being built - which didn't make for an
easy replacement(!) [BTW "SDS Max" standard seems well worth having -
I've got pick and chisel bits 900mm long and they work well - and the
shank is strong enough you can waggle the drill around to free them is
they get nipped - I'd say masonry drill up to 16mm go SDS; greater than
16mm go SDS Max])
I would have had the roof of the outbuilding boarded-out in another
half-day, but the 'flu struck and that was over 3 weeks ago. Proved to
have been a bad one - quite a spike in people ending up in hospital - to
put it in perspective.
I liked the look of a "Myford ML7R" on sale locally - but you cannot win
'em all. Timing can not work out.

machine tools if the workspace is mainly a welding and metal-fab. space.

----------------------------

I'd look at the diameter and length of parts of the ore processing equipment you might be building or repairing. My 10" diameter capacity lathe is too small to refinish its own speed reduction pulley, or my brake drums and rotors.

Unless you need to turn long solid rollers a lathe with some bed wear might
be acceptable. Usually the tailstock end has less wear and could turn each half of a roller or thread the end of a shaft. My little lathe had over half
a mm wear in the ways near the chuck which didn't affect the small tools I made with it.

The spindle bore is important when turning the ends of long shafts to fit salvaged or rebored pulleys or gears. The slowest turning, highest torque shaft on my sawmill calculated to 1" OD for mild steel fatigue life at 10HP. That happened to be right for the metric chain sprocket I turned and splined the shaft to fit.

The precision slides are bare steel. Machines left outdoors rust quickly, I was lucky with the surface grinder because its ways are shielded from
grinding grit (and rain) and it could clean up the top of its magnetic
chuck. I still had to buy or make some replacement parts.

A lathe and mill are necessary, a surface grinder not so much but for $100 I couldn't resist. It's probably saved several times its cost by resharpening high quality endmills and large taps I bought dull and cheap. For me the
other essentials are a horizontal bandsaw and a bench grinder which shapes
and sharpens HSS lathe bits, my old, slow, worn lathe isn't happy with carbide. The vertical mill is a fine drill press. Many have found the 4" x
6" bandsaw too troublesome and bought larger though mine is OK with some changes. The 4x6 with a very coarse blade cuts 150mm (6") square timbers neatly enough to expose the cut ends in a retaining wall.

I also have a horizontal mill which is less versatile but more rigid and
cuts considerably faster, and an abrasive chop saw for harder steel such as rebar and tubing too thin-walled for the bandsaw until I found a 32 TPI
blade. A belt sander is handy for deburring sharp edges, a small portable 1"
x 30" model is enough for me and claims no permanent bench space, like the chop saw (and often the bandsaw) I use it outside.

A 4 jaw lathe chuck will do everything, including hold a smaller chuck that grips small rods or even a drill chuck for very fine work. Centering a shaft in one is slower but more precise than a 3-jaw, especially a worn one. Part
of my qualification for optical work was showing I could center a 4-jaw to 1 micron, another was hand writing my name 0.5mm high. I can carve straight strokes but not curves 0.1mm high, to label an IC bonding pad on the silicon wafer.

1 micron is 0.4 divisions on an indicator graduated to tenths of 0.001". I have a B&S BesTest graduated to 0.00005", 1.25 microns, $25 at a second-hand tool store.

5C collets are very nice, partly to avoid the danger of spinning chuck jaws. You need only the collets for standard sizes of rods and shafting. Work held in them can be moved between the lathe and milling machine for indexed cuts. My small 3, 4 and 6 jaw chucks are on 5C mounts for that purpose.

The lathe makes circular and rotating parts, power transmission, the mill sliding or stationary ones, the frame. A lathe can be rigged to cut keyways, flats on small parts or splines before you find a mill. Either can cut mathematically defined curves or tapers by making an X-Y table with a spreadsheet and then filing to the bottom of the cut marks.

A digital readout isn't essential especially for one-offs and repairs. My
home machines don't have them, I measure how far is left to go and cut most
of it by the graduated dials. This minimizes the effect of wear and shows if
I need to resharpen for final surface finish.

I would have had the roof of the outbuilding boarded-out in another
half-day, but the 'flu struck and that was over 3 weeks ago. Proved to
have been a bad one - quite a spike in people ending up in hospital - to
put it in perspective.
I liked the look of a "Myford ML7R" on sale locally - but you cannot win
'em all. Timing can not work out.

I've been told - you really really want to have a cover for precision
machine tools if the workspace is mainly a welding and metal-fab. space.

Best wishes to you all and a happy Christmas,

You need to keep you eyes and ears open for what's about. I know a guy
in your area that got a decent Induma BP clone for sub -u500, a bit of a
job to move as a bit heavier than a BP but worth the effort for what he
does. He has various other machine tools all from the area acquired over
time.

When I bought my 9" SB "A", the two guys ahead of me had to make a
phone call - by the time they got off the phone the lathe was mine and
delivery arranged!

Also remind the seller, who may not have been the user, to check for accessories. My 5C collets were forgotten orphans from a lathe that had been sold.

Cash is king. Flea market and second hand dealers tend to have a folded wad
of bills in their pocket, sorted small outside to large inside to minimize fumbling, ready to negotiate and close the sale. When I took the cash out in
a store to pay for hardware my new treasure was missing the clerk thought I was a drug dealer.

I've bought a number of things cheaply that were "broken" by missing
hardware, sometimes special parts a lathe can make, such as a #12 LH chuck retainer screw for a cordless drill.

The Navy lost a $60 million jet to a missing hydraulic damping cylinder rod clevis pin washer that let the pin slide out of one side eye and rip loose. https://www.businessinsider.com/navy-probe-shows-how-aircraft-carrier-landing-unraveled-in-seconds-2025-12

The more detailed investigation I read didn't mention whether the nut had
come off first or the washer was omitted. The sketch apparently showed the
nut OD smaller than the pin, so it might have been either.

The US population is ~340 million, that jet cost each of us two dimes.

That's a nice and very popular lathe, available as clones in Britain. https://www.lathes.co.uk/southbend9-inch/page3.html

I saw one for $300 at a ham radio flea market last year. I had nothing to check for wear nor indoor place to store it and thus passed on it.

This gives an idea of the variety of work that can be done on a lathe. Model engines can be machined with nothing else, using faceplate clamping fixtures to cut flat surfaces.
https://www.lathes.co.uk/south-bend-9-inch-accessories/
I've found 10 inch versions of most of them.

The milling attachment is quite limited versus a real mill, though it's
easier to set at an angle and square again afterwards.

The spindle-nose-threaded Jacobs chuck is nearly a substitute for collets though not as rigid, and safer up close than a jawed chuck for manual
cutting such as filing modified screw heads.

Yeah cash is kinda like having multiple cellphones in that regard.

The push is to force people into a cashless society, but they keep
making banking more onerous and unpleasant. The feds push regulations
and the banks use that as a shield to force even worse policies. I
fired one of my banks just a couple days ago. They took money out of my
mom's account (I'm a signer) instead of issuing a banking instrument for
the cash I was holding in my hand. Cash I was holding in front of them
the whole time after saying cash five times. I accused them of banking
fraud and made them do it over. They did it over. Later when the bank
manger called me he claimed they did nothing wrong, until I pointed out
there was a paper trail, and then he tried to claim they did nothing
wrong because they fixed it grudgingly after I called them out for it.
Then he claimed they don't issue instruments for cash. You have to use
a bank account. Nobody told me that. They just tried to steal from my
mother without telling me.

You aren't doing the right thing when you correct your behavior after
you get caught. You do the right thing when you do the right thing the
first time.

Makes me look forward to my next visit to the DMV where believe it or
not I can deal with somebody competent at their job or who will get help
right away if they don't know how to do something. the AZ DMV has no
issues with cash for all transactions either. LOL.

I still carry a little cash, because on a hunting, fishing, or road trip
a local farmer may have a can of gas or a tire that fits my truck, but
they don't take American Express.

I took to keeping enough in the car to convince a wary tow truck driver to take me home. We are too close to Massachusetts (welfare scammer haven) for them to trust people with older cars.

At Mitre I attended a seminar on corporate management styles in which banks were the model for unquestioningly following the published procedures no matter how inappropriate to the situation. I suspect your clerk lacked or feared exercising the initiative to suggest depositing the cash first. At my bank they are friendly and easy-going but I have to prompt them to make variations.

The opposite pole was unrestrained survival of the fittest, Harold Geneen at ITT or Atilla the Hun, who fought both alongside and against Rome, whichever benefitted him more.

Mitre and to a much greater extent Segway were run as an engineers'
playground or artist colony, although at Mitre they limited themselves to theoretical work and left the detailed design and construction to techs. At Segway the engineers machined their pet projects and left me with the electronics and manual metal hacking.

The military is somewhat similar, following the rules is usually an adequate defense in peacetime. In wartime success could justify disobedience, for example the uncommanded Union charge up and capture of Missionary Ridge
which controlled Chattanooga, or almost everything Rommel did on his own without or against orders and got away with. Many high ranking officers
could handle one but not shift to the other.

My father commanded an ordnance company in New Guinea under MacArthur and
Air Corps General Kenney, a trained engineer who practiced and encouraged unofficial tinkering, notably with B-25 bombers "midnight-requisitioned"
from an unused consignment to the Dutch (who lacked bomber pilots) and off
the records. The Japs had driven the Dutch from their East Indies
possessions to Australia.

https://www.thearmorylife.com/b-25-mitchell/
The parafrag bomb was Kenney's own invention, and he personally perfected skip-bombing, which is like skipping a stone on water, a tenth second delay fuse let the plane pass beyond the target ship's side safely. They flew so
low that a plane returned with part of a bombed Japanese ship's logbook
stuck in the engine cowl.
http://pwencycl.kgbudge.com/P/a/Parafrag_Bombs.htm

The Japanese lacked adequate radar to detect gunships approaching at treetop height. A row of them opened up with all those .50s at 1000 yards from a Jap airfield and chased all troops including AA gunners into trenches while they riddled the planes and stores that had to be above ground because the soil
in the only flat areas was waterlogged. The battered Japanese could still defend themselves but not attack and their bases could be safely bypassed.

I have to clearly and precisely state each time what I want done with money already in my account, though they know my preference is to transfer from savings to pay the credit card billed amount, not the current card balance, which would complicate my spreadsheet where each card's billing period is self-contained.

They can suggest investment options on their own. If I remember I'll ask
them about the rules.
