I'm a new member and would like to share my design for another style of shooting table. I really like the one Flotsam posted.
I made mine out of 3/4" EMT Conduit. Table top in the photo measures 48"x48" can be fitted with glass, plexi or wood. There are three height adjustments (12", 21", 37") by way of removing leg sections, or any other height by simply cutting new leg lenghts. The back is a little over 7' tall and is fully adjustable from 90 to 180 deg. I installed castors on the back legs to make it easier to move around. The table folds down flat in 5mins with the help of a screwdriver.
