Hi JA, you are right, I checked my MTO and Rubinar, they are both 1mm.
Canon 200mm (which has a small deformation), is 0.75.
So I for now I need 1mm and 0.75 mm pitch collars.
I think I can use M6x.75 and M8x1 mm taps as tools to try and make those collars, without fiddling with gears on lathe.
If this doesn't work, I will try to cut grooves, one after another (this doesn't need to be proper thread anyway).
