In a possibly fruitless search for an adjustable, US made chuck, I've found that a price list is not a common thing. Bison is looking better and better. I am having suspicions that BTC is making Cushman chucks (sure share the same model number).
Kalamazoo hasn't got back to me.
5", 3 jaw, micro adjustable, adapter for 1 3/4 by 8 tpi. Brass and Tool has the Bison Set-Tru and a 1 3/4 x 8 tpi mounting plate....5" chuck is roughly 11 pounds, a 6" is roughly 23 pounds...
