Here's a photo of my attempt to make a nut from the Torqspline® Screws. I used epoxy and graphite . first waxed and then a couple of coats of spray PVA for release agent. Although the threads turned out perfect, the friction is just much too high. I guess someone could try and use a different type of coating over the threads to build them up but I think I'll just buy the nuts for now.
Another alternative if several of us would like to pitch in, is the purchase of a tap (www.roton.com/page.aspx?id=41) for this particular screw. The tap is quite expensive but maybe if we were going to build several machines it would be worth the cost.
