I used to work for a coach company made the big busses all the movie srars go around in.The material is coriander It was used for counter tops ect. heat resistant ,you can drill it , mill it. heat it bend it what ever. I just drilled and counter sunk some 1/4-twenty holes stuck the bolts through . Bent some brazzing rod at the angles you see. slapped A nut on to hold the rods. Glued a couple rubber stoppers on the bottom corners. Added the snaps from some old swivels. Done Deal. They were originally built to sit by the cash register to display new jigs . Usually if somebody can piddle with something outside the package they will buy it.
