Yes Dakota, thats the biggest I've seen to date. Its 3" on the nuts. The bar to spin it is 28" long and I'm sure you'ld want all of it to spin that bit.
Bob, It'd sure be a heckuva weapon huh? Can u imagine hooking somebody somewhere? I bet they'd come right along... I'll sure trade it to you for something interesting.
1930, that is what they do call those. They were for making holes for tapered shafts to fit in. Like wagon wheels, whiskey barrell bungs, etc. This one starts at 0 and goes to 2" The working length is 6" long. Its in excellent condition but the handle has been replaced with a newer peice of wood I'm sure. Again I'd swap for something.
