Hello
I’ve been skip diving and am thinking of making a few things out of some lovely birch ply I rescued, would love to engrave a hefty pattern into it but it’s already been varnished - does this present an extraction / fumes issue @lasertechs?
Looks like the wood was only used indoors - so hopefully the varnish is nothing too strong. I could sand it off but because of the ply I’m a bit worried it’ll bust through the top veneer…
