So, I finally get around to actually installing the 4 jaw chuck on the lathe. Biggest problem was finding the right wench. I got close, at least I didn't use a pair of Vice Grips.
The chuck is currently on Amazon as a RATTMOTOR 4 Jaw K72-100mm for $70.00
The studs, washers and nuts came from McMaster Carr
