I wanted to have one of those but didn't have time yet to build one. Now I did. It's a dueling tree for rimfire at this time. Can be used for anything else if the plates are changed to match the caliber you want to use. In this case the plates are 1/4" of mild steel. I bought the 22lr swivel thingy at Cambodian Tire with 5 2x2 plates and that's what they have for thickness. The plates are 6" diameter but will make smaller ones in the future. When you hit them with a 22, they are just a tad too heavy and sometimes depending where you hit them they will not flip on the other side. Those are pics of testing phase and before I painted it. I didn't slot the adjustable piece for the angle but that is future plan as well if I switch to different caliber. If anybody want one in the Ottawa region they are very cheap to make and I can cut them on my CNC Plasma.
