I've recently picked up a few new toys and need some holsters for them. I saw a few youtube videos on doing vacuum forming of kydex and thought I might give it a try.
Here is the box I've built, which will have my shopvac connected to the port on the side.
The top is a simple frame suspending a sheet of 12" x 12" X 1/32" silicon, which is heat resistant to 400* and very pliable.
I'll lay the piece to be formed on the box, lay a piece of kydex (heated to 350* for 2 minutes in a toaster oven) aligned over the piece, put the lid over the box/piece to be formed, and turn on the shopvac to vacuum form the kydex to the shape of the piece.
More pics to follow later...
