What is good for sealing knots?
I'm working on a tabletop glue-up that I'm going to use a router sled to surface plane. There's a couple hard knots in it though - one even has a partial void. I was going to worry about this void closer to the finishing stage of the project, but now I'm wondering if the force of a high rpm router bit might rip it out, leaving me with a hole instead of just a small void.
First, do I even need to be worried about this?
If I do (or if I'm just paranoid), is it ok to just "soak" the knot with CA (superglue)? Or is there a better product for this purpose?
I'm going to be taking a bit off the surface, but would try to be careful to not get more than the knot with whatever sealer is best. I'm going to be using Bush Oil for finishing in case this dictates what knot sealers are appropriate or not.
