I had an email this morning from a customer asking for a semi custom variation of a stock design mold so I headed out to the shop early. As I mentioned in another post we've had some rain off and on from thunder
storm cells.-a Large anvil head clouds.-a It could have rained last night, so I wasn't surprised at first to find some water inside the back door
of the shop.-a It seemed like an awful lot of water, and the outside
wasn't wet.
Sometimes if I get a lot of rain with some wind I'll get some run in
under the overhead door on the wind blown side of the building.-a No big deal.-a Its never an issue.
This morning there was a standing puddle in the back that was running
into my office.-a I stood there for a moment studying the problem and
then I noticed the sound of running water from behind the lathe.-a Where
I tap into the waterline going to my shop fridge and icemaker to feed
the water distiller.-a I use a water distiller for pure water to mix with cutting coolant.-a Probably overkill, but I started doing it years ago
when I was trying CRAPMist, and CrapMist wouldn't recognize the fact
that for long duration projects CrapMist stains aluminum parts.-a-a I've been running distilled water ever since.
I turned off the water to the shop.-a I don't know what the problem is because I'm just to big to fit in the gap behind the lathe to look at
it.-a I'm going to have to move the lathe.-a I guess that will give me a chance to finally put the leveling feet on it and get rid of those
stacks of shims.

finding the need to make metric threads , and on my lathe that means a
set of transposing gears and you can't disengage the half nuts or you
lose register . Gotta back out of the cut and rewind back to the
beginning .

I didn't put the leveling feet on today.-a I just walked one end out far enough with a straight bar and block with one foot.-a It was faster than replacing the bad fitting.-a Looks like the rubber failed inside a push
fit connector.

The highest I've acclimated to was 105F when I lived in a drafty and
poorly insulated top floor apartment, really a finished attic. My
father's family is from Georgia and I didn't mind the summer heat there after two weeks. Two summers ago I was running the sawmill in 95F heat, though under a rain canopy.
Mom's side is colonial New England. I can also acclimate to cold like
them but it takes a while. I'm not nearly as cold tolerant as the Native Americans I knew, just pretty good for a white guy. When I was little
the bedrooms were unheated and the house cooled quickly after the last evening coal fire died. I still heat with wood, the original plus my
added insulation hold the heat much longer.
Now my resting comfort range is low 80's indoors in summer and mid to
high 50's in winter. You can have Arizona all to yourself.

This says you can disengage them, but it still isn't as convenient as quickly moving the carriage back by hand and setting up the next cut
while waiting for the thread dial mark. https://conradhoffman.com/metricthreading.htm
"*When you reach the stopping point, release the half nuts just as you always do, but immediately shut off the lathe. The thread dial will go
a bit beyond the chosen number as the lathe coasts to a stop.
*Back the tool out of the thread just as you always do, preferably
while the spindle is still turning.
*Reverse the lathe motor while watching the thread dial. Engage the
half nuts as soon as the original number comes back to the mark."
Instead of releasing the half nuts I pull up the belt engagement lever
which stops the spindle and leadscrew almost instantly. After the
motor coasts down I finish the cut by hand to the end hole or stack of previous chips by moving the exposed cone pulley, easy enough with
back gear reduction. When done I V-chisel out the chips and smooth the thread end with a triangular file. For me the well spaced controls on
a South Bend are very convenient and I appreciate the smoothly
sculpted castings over bulkier square machined components. I don't ask
it to give the power of a gear head lathe.
On my inch lathe with the 70 position Quick Change gearbox I need two transposing ratios to get all the metric threads I want. They are the standard 100/127 plus 120/127 for finer threads for optics. As the
threading label was missing I made one up as a spreadsheet and printed
it. Linking the transposing ratio into the cell formulas of a copy of
it gives the metric modulus for each gearbox setting. In Britain pipe
thread pitches are different and the spreadsheet won't be correct.
Boston lathe change gears are meant to go on a double splined center
bushing that couples a pair of them together. The bushing bore for the thread pitch that matches my lathe's tumbler and QC box input gears is smaller than the sliding post on the banjo so I machined a new post
and base. I could also have made or bought a plain bushing with the
right OD and bore but no splines and bolted the gears together. https://www.bostongear.com/products/open-gearing/stock-gears/spur-gears/change-gears

I grew up doing summer jobs in the grapes and the cotton. We were glad
to get them. Kid crews chopping cotton and working the packing sheds.
We got more work done and typically got paid better than the labor camp >crews made up of "adults." They didn't even hire the labor camps for
the packing sheds. Acclimatized is a strong word. I can do something I >enjoy without to much whining in the desert in the summer time up to
around 110F unless its humid if I have plenty of water. Under 100F and
low humidity, I'm great. High humidity? F this shit!
My wife and I used to ride our motorcycles everywhere come Hell or
high... well, come Hell. Not much high water around here. We'd stop
at every stop and water up. On bad days we soaked our helmets and our >riding gear on the hottest days, and everything would by dry by the next >stop. We rode in rain, fog, cold, a lot of hot, and once in half a mile
of lemons. I'll give her credit. I mostly did it from my rocking chair >(FLHT or GL1200). She did it from that damned kidney grinder Fatboy of >hers. After riding that thing I don't think I would ever own a softail >myself. I've ridden Paughco save-yer springers that were a better ride.
I'm getting older. I can still do most things I need to do, but I go >slower, grab a pair of gloves, and try to do the worst things on the

the freeway on a 118F degree day I can still do it. I'm just gonna
bitch about it a whole lot.
