Yes.

Let me ask you: Is the use of a handheld woodrouter in a constantly
on, generally loaded condition(since CNC cutting is fairly constant
if the programming is decent) something the mfr. is expecting for
their product?

So what might be the "right" bearing for a router intended to be used
intermittently over 100 hours over a period of time, IS "marginal to
begin with" when used for CNC. Not to mention that the runout
expected and allowable for a handheld, bearing-above/below-cutting-
edge-guided machine is not the same as one moving in thousandths
under computer control... So forget the krytox, and upgrade the
bearings at least! Then when, you have decent bearings, krytox can
often make it even better, IME.

I'll say it again; most ww routers use "motor grade" bearings. Using
spindle grade bearings WILL improve things. Immensely...

P.S. It was never my intention to imply that krytox should be used
with marginal bearings. That would be a misuse of funds, IMO.
