I'm making, I hope, a replica of an old dynamo.
The armature runs between a couple of largish coil pieces with the coils wound on extensions to them. So I need to generate a couple of accurately(ish) dimensioned concave surfaces in which the armature runs. The less clearence the better so long as there is a clearence.
I could do that by mounting an angle plate on the mill or lathe and using a boring head. I could mount the angle plate on a rotary table and stick the rotary table on the shaper. Maybe there are other ways of doing it. I'd be glad to hear of them and to hear people's thoughts about the pros and cons of the various methods.
Since I am machining the rest of the pole pieces using the shaper I'm a little in favour of doing the rest that way if I can.
