Fodder
instead of using flanged bearings you could use skate and not cut all the way through the mdf so putting the flange in the mdf rather than needing one on the bearing. Or just make a small plate with a through hole for the screw and screw that to your gram so putting the bearing outside the new plate and a nut outside that will tension the screw. I've done that and the previous suggestions on a small mdf/allthread cnc for pcb's and it works well and runs fast. |
