Looks nice Ian but I would love to measure the wheel for errors in tooth to tooth distance. We had trouble directly attributable to the worm and wheel in a bought dividing head, we made some 144 tooth wheels for a project at the BHI and they were rightly rejected, for normal clock work the error did not show or was withing tolerance but for a high count the error becomes pronounced.
The easy check I use to test dividing now is get your digital calipers, measure over n teeth, zero caliper , rinse repeat but only zero if less than a previous measurement. you then see a large percentage change in places around the wheel if you have a dividing error its due to worm/wheel form error giving a sawtooth error to the dividing.
