I do like the iridescence the mica brings out, just need to use a larger quantity in the mix.
I suck up the mix from my mixing cup into a small syringe and squirt it into the needed spaces. That part goes quick, maybe 10 minutes.
The holes are a lot easier with the lasered dents. When I tried to just hit the points on a paper template it took a lot more fiddling to align properly. Also found out (re-discovered) that coarse grain (oaks) could care less where you start drilling as they will force the bit around. The laser fixed that issue as well.

If I was going to actually laser the holes all the way through, even with multiple laminations, it would take hours. Best to have a CO2 or CNC for that.
With the drill press, good light, and comfy chair set to a good height I could do a hole every second.
This is about 7 minutes then getting the board done (and done before going cross-eyed).
