Hi,
Using the message system here is easy. Anyway, yes, I use and many kinds of ankle shackles, I get them off Ebay. And I weld them on, and must be cut off with 4 inch "metabo" cutting wheel, all of which I hace at my work, as I am also a metal fabricator. The shackles can be welded on barefeet by placing/slipping a large piece of 1/8 inch or thicker leather pad between shackle and skin, And using a "tig" torch, and filler rod on any closing part or piece of the steel shackles, and I even can add metal safely with rod to fill in places to add strength or security to the shackles, I love it! Not hard to do once metal is prepped with power buffing wheel (to remove paint, rust, coating, etc). Or I also, if shackle has holes for closing, like medieval style, pound a custom fitted piece of steel (pin, rivet, bar...etc) with big heavy hammer into the closing holes of the shackles as they are hot to smash into holes filling them up, and then even welding them into place if need be afterwards.

But at any rate, everything as to be cut off, and usually shackles are no good after, need steady supply of shackles and chains! = Ebay, or "Dungeondelights.com"
I like heavy thick shackles on barefeet!
I hope you enjoyed. I have had many requests to weld on permanent ankle shackles from people on different sites, seems many people (mostly women) would like to have permanent shackles and chains put on their feet for awhile ...
