So I bought 30 grams of blue glow in the dark powder. and decided to try my hand at a grown up Tron Data Disc. I got the idea from Mat Browns glow in the dark shelves.
This is a 10" maple disc that I turned on the lathe and used a 1/8 inch bench chisel to cut the grooves.
After that it was just a matter of mixing up the powder. My confession here is that I thought the powder would be enough to tint the epoxy blue. I wasn't aware it would dry clear. Next time, I would totally tint the epoxy.
After that, sand the glue flush and add a finish. Charge it in the sunlight and enjoy the cool effect in the dark!
