1TB Micro SD cards are about $5664 dollars per ounce.

Roughly 28.34 grams per ounce times 2 since its a half gram.

OOPS! Surprised none of you guys called me out for that one.

I figure the price per pound when I buy surplus/scrap steel. Structural
shapes have the weight per foot in the size and 1" flat plate is considered
to be 40 Lbs per square foot, which divides neatly into fractions. Steel was $0.25/# when I bought for the sawmill and gantry, and $0.50/# this past spring.

I bought one of those vises to mount on a bumper hitch for large outdoor
work but it was so clumsy I traded it for an X-Y table and use an antique
leg vise instead. The X-Y table would be the repositionable cross slide tool holder if I mount my spare SB lathe headstock on wood beams to turn large diameter wheels. Lathes were once built like that, from watchmaker to steam engine flywheel size, avoiding the difficulty of making perfect long
parallel ways by hand.

I have a Harbor Freight swivel vise. I use it about 50/50/50/5 with the
4" Columbia vise on the back other bench, the smaller Harbor Freight
swivel vise on the front bench, and the Zyliss vise on the machine room
bench.

Seriously its a great universal vise for most casual handyman types, but
the center rotation took a while to get used to. You would think the
bottom jaws would be more use with its pipe jaws, but I haven't used
them in years. Good thing too. One of those internal jaws fell out,
and I have no idea where it is. I'll have to make one before I can use it.

I would say for machine shop secondary work I like the fixed Columbia
best, but not by as much as you might think. I think for most people
who just want to have a vise in case they might need one, the larger
Harbor Freight swivel vise is a lifetime vise.

This one, although from the picture it looks like the pipe jaws are cast
in now instead of a separate part.

https://www.harborfreight.com/5-in-multi-purpose-vise-with-anvil-59275.html

They also have a heavier version for a hundred dollars more in their
Doyle line.

https://www.harborfreight.com/5-in-multipurpose-vise-with-anvil-58157.html

Funny. Except for the paint color (mine is blue) mine looks more like
the Doyle than its name sake Central Machinery current version.

Same here. Looks more like the Doyle...

If you look at the very last picture for the Doyle after clicking the
+3 more button... I took those V-shaped plates off on the bottom off
mine. The ~1/4 inch or so recess for them is good enough for gripping
most wide items with a decent hold. That increases the max-opening by 3
inches on mine. After doing that I probably use the bottom equally with
the top. With the wider opening I often use it to press items in/out
too. The three exposed bolt holes also can be used.

The other one is mounted on a custom 2 inch tube that fits a Reese
style hitch. Tube sticks out maybe 2 ft and then up 2 ft. Besides using
it on a vehicle I figured mounting a 2 inch hitch adapter to something
stout would work with it too.

When I was still working in 2-way radio service I had access to a
heated shop you could drive several vehicles into. Their work bench was
a joke and it had a small, maybe 3 inch vise that had been beat to
hell. Bent sliding handle, chewed up jaws and almost a full turn on
the handle to move the jaws. I'd put this vise in the back of my truck
and bring it along when I thought it might be handy for working after
hours on my stuff. Had a cap on my truck so it wasn't obvious in the
bed and out of the weather. It worked nice for those occasionsEfOeN+A

For you truck vise guys...

1. Harbor freight makes a receiver / draw bar vise already. As do more expensive brands like Wilton.

https://www.harborfreight.com/6-in-hitch-vise-58880.html

2. Harbor fright and others make a simple flat plate bolt on receiver
draw tube. They are cheap, and work great on the bottom of an old
school heavy step bumper even if you can't or don't want to mount a
proper frame mounted receiver, and they also work great under work
benches and welding tables for those who don't want a permanently in the
way vise on their work surfaces.

Cheap: https://www.harborfreight.com/automotive/trailers-towing/hitches-receivers/3500-lb-step-bumper-receiver-69673.html

Better:
https://www.harborfreight.com/5000-lb-step-bumper-receiver-69670.html

I suggest in any case add some holes, welded on nuts, and clamping bolts
to the receiver draw tube for making the vise more solid. Receiver
tubes and draw bars are inherently by designed a little loose and sloppy.

For a welding table if you happen to have a piece of draw tube laying
around you can just weld it to the bottom or legs of your welding table
(if you have a real welding table).

It occurs to me that using a draw tube mount at a 45 at the corner of
the of the rear of the vehicle might be ideal for working clearance.

This is something I will consider as one of my plans (of which I have
many crazier ones) is to turn an old utility body into a service
trailer. The idea being when a friend (fortunately I only have a few I
would do this for) calls and needs help with a project I can hook it up,
and go. I have duplicates of most tools (maybe all) or triplicates or quadruplicates I would use in the field I can just keep the trailer
loaded and locked up. Only a few things I might take out when not is
use, like one of my OA torch rigs.*

* I now have enough bottles, hoses, and regulators to setup three OA
rigs. I keep two setup now. One in the front of the shop, and one in
the rear. I really don't want a rig to sit out in the sun when not is
use. That's why I probably wouldn't leave one permanently on the trailer.

No I am not planning to get into the handyman business and I definitely
don't plan to get back into contracting. It will just save time when I
do decide to help somebody out, and it will save some space in the shop
or my storage containers.

I spotted that when it first came out (Hitch Vise). It has the problem
that Jim mentioned, it's too close to the truck. Kinda low too which
for emergency usage wouldn't bother much but it doesn't swivel either.
Makes sense the way it was designed but would be a lot more useful if
it could be swiveled...

I can't remember for sure but I think mine sticks our far enough to
clear the tailgate when open. I don't have my truck anymore to check.
Having it stick out farther than the tail gate when open and be at a
similar height would be the most useful I think. Could use the tailgate
as an impromptu workbench.

Those Reese style bumper hitch add-ons is exactly what I figured could
be used to hold the vise setup in other places. Sure wouldn't need an expensive, heavy duty one for this usage...

I had a Reese hitch on the front of my truck too. Heavy duty enough to
be used for pulling it or others out. Often used the front hitch for
the vise.

That's the first size I grab to pull a small tree or such. I build shed
frames with snow load and hoisting in mind, but away from structures the
hoist needs something to hang from. If you have flat ground a tripod with
the usual commercial designs of folding leg head made from strip or plate steel should be enough. I have to be able to move the legs around freely to dodge rocks and adjust to slopes and came up with a flexible, trickier
design I can't analyze for strength for its 3D compound angles and self-adjustment to leg angles under load, so I proof test on immovable
stumps.

A tripod head with rigid leg sockets could add a bending load to the legs
that decreases their capacity. I try to keep the loading centered in the
tube with pinned joints at the top and balls at the bottom. Both sides of
the pin (bolt) are loaded but I can't prove they are equally.

2-3/8" x 8' chain link fence posts should be plenty strong, I haven't broken
a lighter tripod of 1-5/8" posts with my 3/4 ton hoist, and it's easier to carry in one hand with the hoist, sling and baseplates in the other. The
feet are acorn caps resting in beveled holes in steel or aluminum
baseplates, some screwed to larger plywood. Three 6" to 8" rounds or squares support a full load on all but loose sand. A loop of bright cord on each
makes the baseplates easier to find, recover and carry. The tripod is much handier and more stable than trying to stuff a floor jack under a trailer or riding mower with a flat tire on soft ground.

A piece of of 3/8" chain hung from a wire rope clamp U bolt with a shackle
to hook into drops the hoist body and lever below leg interference.

Don't loop the lift chain as a sling, the hook can do damage. For the load sling chain a grab hook on one end and a slip hook on the other is useful. I like the pin on the hook removable by hand so the chain can be slipped under
a root I want to pull without digging up the rock under it. The slip hook
lets multiple turns of the chain pull up tight around the load, like a
sapling you want to pull upward, the grab hook with some slack avoids an excessive tension factor that can overload the chain. Slings suffer abuse
and do break.
https://ashleysling.com/calculating-sling-angles/

Both 5/16" and 3/8" hardware store chain are rated for over 3/4 ton, though 5/16" not by much. I have slings of both to cover tight spaces among roots
and heavier logs. I didn't buy or need Grade 43 and Grade 70 chain until I
had 2 ton logs to lift.

It matched an older 2200# scale almost to the pound at 1500#. If used to
proof test by hoisting on an immobile load like a big stump you have a
maximum you know to stay below, even if the scale isn't accurate. I used one at each end to lift and weigh the 4500# log. I considered their costs to be accident insurance.

Yeah, that's a reasonable way, though I'd test to twice the claimed
capacity of the chain hoist (limited by the scale), and four times is
the formal standard for hoists.

Joe
-----------------------------------------
I believe they are designed so the handle force becomes very high, like
100#, at the rated capacity. The smaller ones move faster. I only proofed
the home made tripods, not the commercial hoists. When a hoist seemed near
its capacity I changed to a bigger one, I have 2000, 3000 and 4000# and at times all were in use.

Four times the rating is the design breaking strength for chain except Grade 43 which is three times. The proof load is two times the rating. Hoists may
be different.

My recollection is that all hoisting equipment has the same safety
ratio, because the weakest link is by definition what fails.

All good advise, Thanks againEfaiN+A

My recollection is that all hoisting equipment has the same safety
ratio, because the weakest link is by definition what fails.

I believe that for American-made equipment like CM, for imports and
shop-made I have to see it first. When I find that mass-produced items don't meet spec they usually are quite close. There's an unofficial test protocol called "Test Until Pass" for when the failure is within the randomness of
the results. Failures outside it are sold as a lower grade, or were when I
was in the custom test equipment business.

I've seen that as well, but for hoisting equipment there are very
specific legally enforceable requirements on safety margins. But good
luck enforcing that against a Chinese manufacturer.

This is for chain.

I'm sure that there are rules for manual hoists, but have not the
energy to find them.

That's my experience plus the Army field rigging manual and boy scout training. I didn't mention the preceding failures. Tripods appear to be the standard minimalist answer if you don't have a forklift or bucket loader. A neighbor does have a bucket loader, limited to 900# which isn't a big log.
My other lifting devices on what little fairly level ground I own are a 1
ton shop crane fitted with outdoor wheels and a hitch coupler for my garden tractor, and a bed crane for the truck. A lever hoist is the most versatile, for instance to level and support a 6x6 landscaping timber on my horizontal bandsaw so I can trim the end with one cut.

That matches what I've read and been told by the logging chain dealer. https://www.chappelltractor.com/learn-about-our-tractor-excavator-utv-equipment-dealership--bbchain

Apparently overhead rated chain differs in being an alloy that's more able
to deform before snapping than carbon steel Grade 70 and below which can be (and I've seen it) brittle past its yield point. That makes it better for jolts like an electric hoist startup. He said Grade 80 is almost as
expensive as 100 so that's all he stocks. The links on 80 and 100 are
shorter and won't accept the pin of a similarly rated shackle except at the end.

The useful fittings he had that I didn't know about are grab hooks with a Cradle that spreads the load along the side of the grabbed link and Hammerlocks meant to make multichain slings as when disassembled their
smaller end fits into suitably rated chain links. They can be punched apart again but not easily while hanging. https://www.riggingwarehouse.com/115-gr100hl500-1-2-grade-100-hammerlock-style-coupling-link.html?

I bought a lever hoist from a discount store that barely met the
requirements for truth in advertising that it was a hoist. It lifted all
right but jammed too easily on lowering, and internally looked like it had been hammered out by an apprentice in the 1700's. If the chain freewheel is disengaged only luck and bad words will reengage it again. He had bought
only that one sample and I was the guinea pig tester. I kept it to lie in
the dirt and hold the feet of my shear legs from spreading, which avoids trying to lower a load.
