As the OP I can confirm that my threading tool has a small radius on the tip, at least I got that bit right! I would however, point out that aluminium is an excellent choice for the exhaust adapter as the engine it is fitted to is not on a motorbike but is a 20cc four stroke designed for rc aircraft, see my previous post for details.

Having made the spindle turning handle I intend to cut the threads by hand turning the spindle with back gear disengaged, did a trial (without workpiece) this evening and it's easy enough to turn. Just got to cut and shape another piece of 15mm plate to try it out for real.

Thanks for putting me right on the material point and good luck with your turning!
