Re: (New?) Composite Panel Construction Technique

I love learning, so even though it’s another delay and a $50 sheet of plywood that I didn’t want to buy, I’m still smiling and enjoying the journey.
I can’t recall the reason at this point, but I either ruled PVA out for some reason or just decided to not use it. Not sure. Nevertheless, the part did demold really easy with the Frekote770 and Partall 2 wax. The problem was that some epoxy made its way into the corner between the aluminum frame pieces mechanically locking the part to the frame. And since the frame was essentially glued to the glass (because I didn’t use mold release there) when I lifted on one end, it twisted the frame (and the glass) until the glass couldn’t take it. If this happens with in the future, with mold release between the glass and frame, the frame should just pivot up along the outer edge where it’s being held down with gum tape and not break the glass.
The new table is built, so now I have to clean and polish the glass and redo the frame.
Cheers!
