got an Idea to try this As some of you know I am in the metal stamping business , Our company has a CNC turret press capable of doing some pretty cool things!! Sooooooooo Shooperman put his brain to work ??? I have heard many club members looking for inserts that you can use with air-tites well here is the prototype done with 3/16 thick cardboard and a direct fit air-tite ! Nice snug fit wont spin or fall out!!!!!Now that I know I can do it time to try it with heavy Felt and Plexi-glass!! if this works gang the Shooperman will show the final project!
