For those who do not want to use a chair, you can make a nice frame out of pvc 1 inch pipe for about $25.00. What is needed is 3 10 ft 1 inch pvc pipes, 10 tees, and two 1/4 inch threaded rods with wing nuts. It takes maybe an hour to cut the pieces with a hand saw. I did not use any glue, may or may not be needed.
The bottom legs are 30 inches and the top target holding legs are 23 inches. The spacers are 21 inches but could be longer if you want it wider, that is just what fit my ballistic backstop from my chair. The spacers between front and back is just the distance that the tees on the bottom required. There are two threaded rods with wing nuts between the front and back. You need four 2 inch spacers for the bottom tees. Bottom back legs are about 16 inches
Show with ballistic backstop and with the bucket to catch spent wax. Note the cords on top to hold the cardboard. I may or may not drill holds to fasten the cords at different heights. Still a work in progress.
I have not used it yet but it should work well. If the joints loosen up with use, I may have to glue them. For those of you that spray wax more, maybe a little wider would be better, but for me this width works just fine. I intend to get a light canvas that wax will penetrate for the front instead of cardboard and then stick 6 inch targets on it.
Anyway, no glue yet so it can be taken apart if it becomes an auction or gift item.
