[QUOTE="oexing, post: 130766, member: 1493"] Wow, extremely fast thread rolling - but this would not come really handy for a private workshop. I got, with some luck, two sizes of rolling heads and several rollers for pitches and diameters. The procedure is much like spokes threading but pitch dia. is adjustable for more thread sizes with one head and rollers. You can set thread length and a stop will disengage the rollers by opening via eccentric pivots inside. Once you have tried diameters for turning bolts and did a few threads for pich dia. you get perfect thread fits to your liking at perfect surface finish too, no troubles with blunt dies and chips. So I had a number of M 8 titanium bolts for engine case through bolts - because I can . But yes, for one or two threads it is too much hassle to set this up when you have no preset head ready.
