Basically a sprocket wheel without teeth--like this:
This is for a woodturner's eccentric chuck attachment I designed--
I'm hoping somebody will have a small pile of these in their scrap bin, I could use about a dozen perhaps more. But if you have just one, or 5, let me know. I can turn down an oversize piece, but will need the 1/2" bore.
I could use a sprocket wheel or gear and machine it down for lack of anything else.
I'd consider welded construction if the weld were on the flat side and didn't stick out, or a very nice looking full-circle weld at the joint between the hub and plate.
Be nice with the price please, I have to make a little money on this. Thanks,
