I use a QD bushing with a sheave I turned down for a back stop. I tapped the sheave with 1/2-13 and use those nuts to press and hold the work tight. The tailstock is tapered and seated inside there with a bushing. The dead center shaft is 1-1/2" and my pulley bore is 28mm. So I turned down the end of the work holding shaft and made a bushing to bring it together. I made up two work shafts and have the next set turned to diameter as the Knob Hobber cuts teeth.Do like.
Your tailstock and outboard support is...interesting. I see a taperlock bushing, and maybe a bearing carrier, but the rest is hard to figure out.

When I find an 8" Ill swap it out.. I'm building a machine to cut tapered accelerating pitch feed screws out of cored poly bar stock and I need another rotary A axis to do that. I'm on the hunt for an 8" if you see a deal.
FYI....... the OEM price on those pulleys is $400+ US.
