ive made a homeade hanger, been spending last month somewhat perfecting it with metal clips, I have an old multi purpose gym, that ive been hanging with the cable pulley system. Problem im finding, should have gotten bigger Riser clamp because of water tight gasket I glued to it, makes it little smaller, but the holding power of it, is unreal. Hanging with it on tightly, after about 20+ mins my Head goes fairly numb, and a little purple, mostlly due to the hold and weight. Last week or so the clamp has been getting looser and looser with the screws, so I must be doing something right. Ill update my post of hanger.
