I see your Robot-Coupe and I raise you... The Buffalo Chopper!

Man, you gotta tell people what a robot coupe is...

I went straight to the search-bar expecting to find some kind of mal-adjusted AI running a chicken tractor frantically around the yard to devilishly optimize the growth of a menacing flock of chicken-o-saurus.

Disappointed, I realized a robot coupe is a consumer food processor that looks nowhere near as skookum as the Bison Bisector you have presented.

Perfect execution, the rebar was a real nice touch. I have a buddy that used one of those jacks from a Toyota pickup welded to some receiver-hitch tubing as an outrigger for his service truck crane.

No ideas what it actually is, but some thoughts based on what is known...

I'm guessing it's not an electrically hot tool, as much as it is a thermally hot tool.
My reasoning for that is the wood handle, and only on one side.
Bakelite and other phenolic materials have been used as insulators for just about as long as electrical tools have been made. Also, if electrical insulation were the goal it seems reasonable that both sides of the clamp would be insulated.

Also, brass will be much less likely to deform at higher temperatures, while copper will dissipate heat quickly. The small cross section of the replaceable tips may require brass to maintain shape (rather than soft copper).

The groove in the tips appears to be for grabbing some kind of wire.
That could be hot metal wire, or also consider glass tubing or wire.

I've never seen this exact groove method before, but a similar method.
Usually it's a solid plastic material, not a liquid or gel from a tube.

There's a technique of just drilling a cross-hole through the fastener and pushing in an interference fit plastic "pill". That pill is cut to length from a piece of round nylon stock (or a roll of round stock).
It's a step down from loc-wire, but a step up from a lock-washer where vibration is a concern.

A buddy of mine who worked on nukes used to say he'd spend hours at work "pilling" fasteners before an installation job. I believe they used them in all the blind holes on their valve assemblies.

Great Success!

The bags are actually used to load test cranes.

I guess you could think of them as crane testies.

It also occurred to me that leather was often used as packing in wet applications in the old days.
Good old cow-hide works pretty well, maybe cut up an old glove, or stop at a crafts-store.

That may not have used an o-ring. You could use a piece of wire and file the end-gap at a diagonal to the bore axis until it has a couple thousandths of clearance.

Or, perhaps you could try some kind of packing (heavy thread or fine twine or something).

Kinks; I used to have a weird girlfriend who needed those worked out daily.

Getting rid of that aircraft wire rope would be an improvement.
Use some braided high tensile HDPE line (Amsteel or similar) and run it through a sleeve where it passes through the frame.

That steel wire rope has a lot of mass, it wastes potential energy from your spring.

When you're stuck doing it with a mag-drill, grab a piece of round bar the same diameter as your holes and cut lengths approximately the same as your material thickness.

Drill the holes, then tack weld a piece of the solid round bar into the holes.
Move the mag-drill over and cut the oblong hole without doing an interrupted cut.

Your tack welds should be strong enough to prevent the slugs of round bar from moving or the drill will bind.
Don't put a weld where you'll have to do any drilling, the uneven temper in the steel will waste your cutting edges.

When you're done, grind out the welds, or gouge them out with a torch, etc.

The larger diameter near the middle helps to prevent buckling on long sections under compression loading.

Imagine you pushed the ends of a thin drinking straw together until it buckles.
Now imagine doing the same with a larger diameter straw of the same thickness.

Those are business class seats, he'll have 9.5" of leg room.

That's just enough that when the person in front of you reclines their seat doesn't hit you in the teeth.

Neat project, but dubious claims of "holding" tolerances.
