epoxy or friction fit flange bearings?

[forgetcolor]

For those who used flange bearings similar to those shown in jgro's plans, are you typically epoxying them into the appropriate locations, or do they hold fine with a friction fit?

I think friction fit should work. I didn't use flange bearings, but made round pockets for skate bearings at each end of the lead screws (I used 8mm threaded rod for a lead screw). I didn't use epoxy, the bearings are held in place by the nuts on the end of the lead screws. I used double nuts at each end.

In JGRO's original plan I think there is just one bearing per lead screw. I would use one at either end: like in the Joe 2006 design. This lets you apply more tension to the lead screw, to stop it whipping about.
