Perfect !!

I think lefty got it

I am plumb stumped, can't see any to call it a pig castrator

Maybe some sort of device to measure or calibrate tire camber settings?

It's for lapidairy work

Theres nothing on that thing to even give me a hint of what it is/does.

come-along

Well it is hanging in my late partner's shop and his SIL is asking me what it is.

I have never seen it before. My partner was really into chainsaws and he owned and operated a sawmill.

It COULD be some sort of jig for grinding teeth on a saw blade or an attachment for another tool along those same lines

A tool for putting the set on a sawmill blade ?

I don't see a bubble gauge or any type of meter to measure camber offset from straight up and down.

It's designed to give you a mechanical advantage over using your bare hands but like Cotton said I'm not sure it would be worth a darn for castrating pigs or even muslim invaders so I guess just scrap the worthless daggum thing. You can't enen set it on fire and test the smoke alarm or respone time from the local fire department which of course livens up any man's day.

Junk unless Wolfie can figger out how to use it to cast big bore bullets with it and hand load rounds with no kick!

Yeah it very well could be something along those lines. He did have a tool for that but it has been years since I have seen it.


The sawmill used a 52 inch circular blade.

The teeth had inserts that could be resharpened. I am leaning towards this thing being a jig that could be clamped on the blade and using a hand powered grinding wheel to sharpen the inserts

Clearly a vintage Thingamajig that bolts on to a Dohicky. Used to ajust tension on a whatjumacallit.
Really that simple

My thoughts exactly Mac !!

Thanks to Stinkypete. It is in fact a jig for filing large circular saw blades

Pig castrator

Okay. I'll come along, but what do you think it is?
Our go to answer for such contraptions as this is, "Why, that's a hoe binder. I thought everybody knowd that", then turn and walk away without looking back.
