I made this 12x 18 hot plate to use for warming plates for applying ground and applying ink. I’ll set an electric hot plate underneath it. Any suggestions for fastening the plate to the frame?
The plywood is only 1/2” thick. If I’d had a router I might have set it just inside the frame making it flush with the plywood. I’m thinking of drilling holes at the edges and use some smaller screws to hold it in place. That would render it not very useable should I decide to use it as a plate to etch in the future. Now that I think about it, maybe I should just use a less expensive metal plate sized to fit just inside the frame on plywood shim set to have it flush out at the top and just gravity set.

Thanks for looking and any feedback,
