2o years ago in Rehab they had standing frames that were basically plumbing pipe screwed together and bolted down on heavy duty plywood. when you stood up you strapped a wide leather belt behind your heels, one in front of your thighs and one behind your butt. It was simple, sturdy and worked like a charm.
I was thinking of making one but it has been so long and I can't remember the details. Anyone know of any construction drawings for a standing frame? It seems ridiculous to spend 5k or better on the store bought frames.
