I have always routed for binding in the white, but am wondering if it would help to avoid tear-out if I put a thin seal coat of shellac on the sides before routing. Of course, I will scrape and sand before my finishing schedule. Does anyone else do this? Pros/cons? Thanks!

Yup! A spit coat or two of blonde does wonders. Along with a spiral downcut bit you get a razor-sharp edge every time...

I don't see any problem with doing it but don't see any reason to do it either. Just another step to brush it on and sand it off. I do it after I cut the channels to protect the end grain from the CA glue.

I am sealing with shellac generously before I start cutting, but I don't see how it can really protect from tearout. Best tearout protection is to pre-score with a sharp gramil. What I find the sealcoat invaluable for is to protect the top from the sticky fishglue I use and the binding tape. I still tend to pour too much glue and that makes a real mess.

But what if you intention is to later pore fill with epoxy? My impression has been that one does not put epoxy over shellac. Pat
