Looks like a rotary throatless shear. If I had a chance to get it I'd have another tool I don't have room for in my shop.
I would try it for a couple hundred dollars. How much could it be bought for? The stand and other parts could be repurposed if it didn't work out. Scrap price would be close to $200 I would think.
I would buy it if you have the room for it. Yes it would work great in hot rod shop. It should cut up to 12 or 14 gauge metal. $300 not that much considering it's size and uses.
I have a Marshaltown rotary throatless shear. Mine is smaller and hand powered. Kept sharp, it works well. I can get speedy cut on it on 18ga. I use my Beverly B3 for anything thicker.
I guess I was interested because it looked cool I think I would rather invest the $ in a bench mounted throatless shear. I still going to see how good a deal I could get on it. It does have a cool novelty quality.
A throat less sheer that size typically is used for thicker sheet stock. There fore cutting way thinner stock may require the cutting edges be sharpened and adjusted . Otherwise this could just bend the cutting line on the thinner sheet stock and not cutting. Vic
I was also working out how ya use it. Looks like you feed with one hand and work the clutch handle with the other? Seems awkward unless it turns super slow. If you could work it with a foot pedal than that would be much easier to use. At least in my brain
If you look at the pulley size, they do turn quite slow. I ran one similar, only it was a large C-frame, heavy casting.
That may have been converted from belt drive some time in it's life. A local machine shop has some old belt driven units outside that are probably more in line with the idea of it being a decorative piece.
