Thanks for your info Dave. The knot compound is Colron Kotting compound, it
doesn't give a description on the tin but judging from the smell (it smells
solvent based) it's a resin compound.

Any ideas on the router speed, full steam or slow rpm?

Matt, it's kind of hard to tell with knots. You can run the router over
one of them and it will be fine. The next will blow out like it was
shot out of a cannon.

I would take very light passes over the knots so as not to allow the
router bit to get a good grip on the them.
What are you going to seal them with? Epoxy?
