I just got a slab of Coquina (Script Rock) from eBay. Unfortunately, I didn't read the description closely enough and it's only about 7mm thick (and 5" x 7"). Being so thin (and soft), I'm sure it's going to disintegrate in a tumbler. So here's my idea… cutting it up in 1" squares with the saw and gluing several layers together to bulk it up. I think it might turn out really cool!
Has anyone here ever tried something like this?

I feel like Coquina is such a common material that it might be more efficient to simply locate another piece, but I'll be interested to see how your experiment turns out.

It will go fast. That is all. Most slabs are 6mm.
Keep an eye on it.

What did you get the slab for? What size and kind of tumbler are you going to use? Why not use a flat lap if for display and put a backer on for extra thickness if needed? I have tried Tampa Bay coral slices in my vibe and found undercutting to be challenging even when constantly checked. Good luck.
