Ok, so I'm thinking about doing some laser engraving on tree slices and since I've never worked with these before, I'm needing some advice on how to prevent cracking.
Can I leave them in the garage, esp with colder weather here, to dry them?
How long for a 2"-3" thick slice to dry (typically)?
Does diameter matter (this one is appx 15")?
Do I need to seal them? Top & bottom only - or all sides? Or is that counter-productive?
Any ideas on how to preserve bark?
I'm not sure about finishing procedures at this point... may/may not include sanding, stain, poly coat...
