I've read a little more on some other sites about this prewinding prio to the second loop business. I think I was really making it bad for myself by keeping the two bundles twisted and wound around each other. From what I can tell you are supposed to unroll them to where the strands in each loop are not twisted at all, then actually twist them backwards several times. Thanks for the advice. And Justin I'll probably make a simple jib where I can wrap strands around three nails, that'd keep the string off the floor in the shop if nothing else. Probably still have the problem of keeping track of just how many strands I have in a bundle. NEver fails, I get to six or seven and wonder is it six or seven. Its tough to count them when they are waxed up good.
PK, I've bought some B50 Dacron that wasn't waxed very well, it was a pain. Stuff with good wax works better, and this little business of introducing negative twists to compensate for over-twisting during second loop production, should make a big difference. I never heard of B40. B50 is the traditional material. there's many low-stretch strings, 452, B50+, TS1, etc. Stuff is made of Fast flight, dyneema, and combinations of various low stretch synthetic fibers.
