Two upright pipes for stability. If your weight gets off center, you are "headed for a fall". You can see how easy it is to move the platform side to side at 13:30, if you are on it, your feet can go one way and your head another way, liken to jumping on a pogo stick on black ice.
Your so right, was a bit side to side. I'll be fixing it with upright poles on each side of the footstand to guide it. Trial & error. Thanks for the comment and for watching. Hope you subscribed so you don't miss my other madness coming up.
