Well, talk about it a little more - I want to understand what you are looking for...You are #4 or 5 to show me that. Not where I’m going.
"I have been thinking about a standing shave horse to relieve back pain and to be more personable at demonstrations.
"...I would like to stand erect and have the work at chest level."
So I was thinking Shannon's "Shave Pony" hit all those needs... now it does require a bench or some surface to clamp onto for use...
My thinking would be to design a "stand-alone" version, but maybe the basics could still work???
If not, you must be thinking something completely different....
