Thanks, Dave. I just spoke with a very nice lady there. The roller she suggested would definitely work, however, I'll need 36 of them at $5.96 each, so that price exceeds my low profile caster idea. I sure appreciate the tip and the link, great stuff there! 73, Rick/K5IZ david knepper wrote: > Hudson Bearings Inc. at www.HudsonBearings.com > > > Dave, W3ST >
