Crown Wheel Run-Out
#12
Bob,
My lathe is a Boxford 4 1/2” model A fitted with screw cutting gearbox, a very useful late for A7 work.

Alan,
I agree with your comments about checking the mating faces of each half of the carrier.
I mounted each one in my home made mount on the lathe and each face proved to be a few thou out, I took as little off as possible to achieve full contact all the way round on each carrier, also the crown wheel mounting face.
Surely machining all three contact faces is a must to achieve total accuracy.
Below is the other half after facing.

Roger
