Well, I got a new drillbit, thought it would make it a lot easier to cut a hole in the copper rings, but nope…gonna have to get a different one which sucks. I have been cuttting the 1 inch copper pieces into bits, which works ok. I get 4 untill the piece gets too small for me to cut em with that hand wheel cutter that I’m using. Now, to mix up some resin and fill a few of them, see how that looks and works with the different backings. Gonna use Aluminum foil and plastic wrap, see which works better.
