Kiln dried rounds splitting
(lemmy.world)
Advice needed. I sanded the tops of these kiln dried rounds and then coated both sides with shellac. Most of them split a few days later.
The untouched rounds have been stable.
How can I make these smooth and shiny and keep them intact?
I think some people use a vacuum chamber and epoxy to stabilize the wood. I also wonder if soaking the biscuits in a mineral oil bath for a few days might do the trick? Personally I've never had much luck with larger pieces.
