Here’s what I made yesterday. The two pieces glued together (upper), the Ti (lower left) and one of the pieces that was cut out from making the frame (lower right)
(This is all just staged right now and not really assembled)
I put the Ti face down inside the frame (this is the bent up one)
then figured I could just place the cut out piece back inside over the Ti and fasten …tape…it down somehow
Then hold the whole thing down with honeycomb pins. It leaves exposed the exact dimension I need for my file.
Does anyone think there would be an issue having the solid piece on the underside?
