Had a little time to kill at work today and an open cnc machine so I drew up and cut the parts to make a pellet trap. A few minutes over in the welding room and a couple coats of paint and it was ready to go. It's probably heavy enough to handle .22 rimfire but I just want it for shooting my pellet gun in the basement. Tried it when I got home and it works like a charm. 
The main opening is 12" x 12" and the small hole in the bacl is 2" x 2".
