I just made mine from some directions I found on this board. Maybe I used Wayward Son's design, (I dunno).
Damned good design, but I can't find the link anymore.
I used anodized aluminum aircraft bushings, along with some titanium links I made from some . 032" scrap I bought at a metal supply place, and the eleven inch X 1/2", .062" stainless springs I bought from McMaster Carr. And I bought some stainless screws and loknuts at Lowes. I think I used 10/32 screws about 1.5 inches long.
I did make my links shorter than the 1.25" ones suggested by the original designer, and I did have to shorten the springs (not a whole lotta fun).
I put them on my IDI Powerfins (Jetfin clones).
Absolutely love them!! I haven't dived with them yet, but I did give them a vigorous workout in the river swimming with them, and they held my fins on like I was born with them.
I would add that the links can be fabbed from one inch long pieces of stainless steel hose clamp material. Just use parts of the clamp that don't have the thread slots.
I didn't bother putting any kind of padding or pull tab on mine. My booties give me plenty of padding already, and it's really not hard for me to push a bare finger under the spring to pull them off. I haven't tried it with gloves yet, and that's because if I find myself in water that's cold enough to warrant gloves, I figure I must've took a wrong turn somewhere.
