Okay, here's the epoxy "fix" on one of the red mallee burl sets:
Attachment 308376
I used the set-up I put together when I was trying to make homemade paua acrylic laminate scales (then wisely just got the ALVS sheets instead!). It's a lot more even on top than my lousy pic indicates, and I took my time to make sure I got all the edges coated, but I do have some bumps and ridges around the perimeters. Masking tape on the inside flats, with excess razored off.
I'm hoping that if I just leave them in this box with the flaps closed for a few days against dust that I can very carefully even out those bumps on grinding belts once the expoxy is super-hard, then finish with micro-mesh? I assume that cured epoxy is way harder than acrylic as far as sanding and final polishing.
We'll see if this worked after full cure when I try to pin up around a wedge (which I'll keep at a shallow angle to minimized bending). I'll report my success or failure in a few days. If it works on this set, I'll do it to the 1st set I screwed up for 2 saves-we'll see. SHD
