I agree with Leon's comments and the bit needs to be almost all the
way up in the collet. If the bits are too long I cut off a chunk so
that I can have the cutter way up around the collet..
I find that 1/2" collet bits work best for correcting this problem.
I feel 8m/m is still a bit on the lean side especially for cutting
Too long bits are rarely a problem with the Leigh jigs ... with some routers
it can be a struggle to get a dovetail bit up far enough in the router
collet in dovetail mode because of the thickness of the jig fingers.
Sounds as if this is what Stoutman is experiencing ...
Be pretty tough to do that on my D4 with the necessary 7/16 collar guide on
the router. That's why Leigh recommends, and supplies, 8mm.
I've used mine in maple, the world's densest white oak <G>, cedar,
poplar, and red oak.
The only time I can remember anything that could be described as
chatter, I was trying to push too fast straight through, where the bit
was encased in wood. I find "scooping" movements, moving left to right,
work much better.
Hope we're talking about the same thing. <G>
