Always a little sad to cut slots into a perfectly fine board but hey, in this case they'll shine bright like a diamond
Cut the slots while the board was still flat (to get a straight bottom) which was a little tricky in a couple of places since the epoxy had filled the starter slots I had cut previously. All went well though, happy with the result.
Here are a couple of pics of the board with one Luminlay strip - this was was "loaded" in the sun for about 5 seconds.
I'll have to measure the actual width of the slots before glueing in the glowing stuff. The strips I have are .5 mm thick and they "just drop in" which means they might be a tiny. it too thin. There's another version measuring .58 mm in thickness which might be a better fit - once I know I'll order the appropriate size.
Then it's glue, cut level, and then sand sand sand to get the 20" radius.
