I was at my dealer a little while back and they had an old Great Dane that had really seen better days. Anyway I stood on it just see what it was like compared to my Stander. It had a spring mounted platform that I thought was nice, so I designed one for my Stander. I cut a piece of plywood to fit, placed it on the platform and marked the holes. I drilled a number of holes for 1/4" bolts. I got some small compression springs and cut them, some in three and some in half. The number of springs will vary depending on your weight. I put a fine piece of wire through the hole and then the bolt the wire is to hold the springs in position when you flip it over. The bolts are to keep the springs from moving around. I put nuts and washers on the front and back rows of bolts to keep it secure. It helps absorb a lot of the jolts.
