When I was making the sliding pinion in the beginning I didn't have the right cutter with the right module and I tried different methods but none had worked.
I made a flying cutter in the end I obtained results with the prototipe in brass but when I used it on steel didn't work and I never understood exactly the reason.
Anyway this is the making of the flying cutter.
I cut a piece off a large diameter of brass glued it on top of a flat piece of brass, drilled the center hole and an off center hole,milled flat the top side,
Then milled the other side
On a heater to break the glue
Almost done
I turned the flying cutter steel post and threaded
Screwed the post onto the brass plate, chucked it into the 70 and turned it concentric.
