If only half the balls contacted one of the steel races, there would also be a bending moment in the brass cage, which I don't think is the case.

There should be a larger tooth or two to match the tiny teeth. It appears on the far right of your photo one tooth is slightly oversize. Or maybe it's my perception of it. Glad you got it worked out.

Christmas roses

It's that time of year again. I made a small batch of roses to be delivered to Georgia within a couple of weeks.

Copper and silver solder, with salt and vinegar to help the verdigris develop.

Easier said than done!!!

From earlier

OD = (N +2) * module, so (51+2) * 2 = 106 mm.

106 * pi /25.4 = 4.1732, carrying 4 decimal places.

Easy peasy.

90 turns x 17 = 1530 total holes

1530 / 51 = 30 holes

30 holes - 17 holes per rev = 13 remaining holes

1 rev + 13 holes will space out your teeth equally.
