OK, I found a great deal on a 8" grinder on CL and bought it to make a sander for Intarsia instead of using my drill press. The flex sander drum from Seyco works great on one side and I want to put a drill chuck on the other side to mount sanding mops. I know it can be done, as I have seen pictures of a setup on SSV.
The shaft on the grinder is 5/8" and is threaded on the end.
How or where do I get such a chuck?
I am sure the mechanical minded have an easy answer. Thanks, in advance.
