Yes, excellent video indeed! I think yours (Funkster's) was worse off than mine, and I agree about making those mounts bigger or perhaps one piece. I too had a slight residual variance even when the mounts were eventually trued up. My shafts had a vary slight, but permanent bow left in them (you can see it slightly by rolling them on the table), and I used that bow to fine tune the residual variance by orienting (rotating) them in the mounts, pointing the bow in the direction I needed to compensate. If you need just a little compensation you would rotate it only a few degrees in that direction. If no adjustment was needed, you would just leave them with the bows outward or inward (not up or down) so they wouldn't affect height at all as the table moved. The amount of bow was not enough to bind the rollers so it seemed ok.
