I just recently became a below elbow amputee. I don't even have my prothetic yet! But I was wondering if anyone knows of how I could make a body powered hook waterproof. I thought I could just replace all the parts with stainless steel (or any waterproof metal), but my prothetist says that none of the arm companies make those little components (at the end of the arm) in anything but steel. I even popped a question to a representative at Ossur to ask if their suspension sleeve came with stainless steel parts. He said only water 'resistant'. Anyway, I was wondering if I could get a metal shop to make the parts or if you guys knew of anyone who has tried a similar endeavour. If I was to take my soon to be prosthesis into water, I know it would rust and seize. I would have to return to the shop every few weeks. An idea I had was just to make a passive hook (captain hook style) but it would lose most of it's function. Any ideas??? Getting the parts in another metal seemed like a good idea to me, but I don't know what kind of shop would make custom metal pieces.
P.S. If you're wondering what it is for, I use to kiteboard and sail and want to do it again.
