Ok, I admit it: I bought one of those Vermont Mfg $4.00
router bits.
I think I started my depth too deep-- close to a quarter inch
in 1/2 in. MDF.
I'm using a rototool with this bit and worked pretty well
the fisrt few passes. Then on about the 4th usage (on one of
Bill Fitmaurice's desings that have rabbeted or dadoes slots)
I got a lot of smoke and a black channel where the bit overheated.
There was a hot cinder down in the shavings too. I kept an
eye on the whole work area not knowing if there was another
hotty around.
So my question is: Is the speed too high or low, the motor
not powerful enough (I had all those good passes) or is the
bit so poor it can only take a couple uses?
