Hi Mark . What is the speedball board model ? I’m after buying one myself , I figured it would be a good way to recuperate in time , after my distant bicep surgery . Regards
@@stormlord3309 Yup I did make it myself and well spotted! I used 2 circular sections of 1.5 inch ordinary plywood, 22 inch diameter. Used a router to cut the wood circles, but a jig saw would do it. I also had an existing circular piece of chipboard which I added to make it 3 layers. So if I were you I’d use 3 plywood circles. The heavier the board the better bounce back speed you get from the ball. Wood Glued them all together, then belt sanded and clear varnished 4 times to add to hardness of surface and a better look. Then drilled bolt holes through from the top to affix the swivel. Added heavy sand bags on top to further dampen any vibration noise and aid speed. And there you have it.
@@MarkLidsterfitnessgeezer Thanks Mark . I aim to do this myself when I am able to start using my arm again. I find the platforms you can purchase are generally too thin and the professional set ups cost a bomb! Good work 👍
