New member here. I am browsing the web looking for materials and inspiration on a project. I found this site searching for 6" steel rollers. I found 2"dia x 6"length steel rollers at McMaster Carr. I found bronze bushings. I found some .375" VBA4 eccentrics made by pacific bearing at Motions Industries. I found some .375 idler shafts. I found 1/2"alum endplates at speedy metals.
I don't have a lathe. I'd like a better axle than a .375 idler threaded into the roller. I would rather find a steel roller cut down to a 1/2" axle on each end or long enough that it could be machined. So I'm wondering, given all the metalworkers here, would there be better sites than McMaster Carr to get rollers? Or should I be looking for a machine shop?
