I had built a router that is using a 6 ft by 3/4 inch acme screw from
Nook. It has a pitch of .2 and I can run at 2 inch a second with no
trouble. But I did notice a vibration, which turned out to be side
play in the nut. Greasing it only helped for a few minutes. I ended up
making a coller to remove this play. All is well now. Anyone else have
this happen ?
