Thanks Chris. I haven't needed the handle all that badly or I would have done something. What I also just noticed is the plastic handle is held with a rivet into the top of a larger extension. New drawing attached.
Isn't there also a raised ring on the inner end, where the cylindrical shaft for the handle meets the flat face of the main casting?
Will you make the handle shaft separately? How will you attach it (a screw through the handle into the shaft, thread the end of the shaft and the hole in the handle into which it will fit (which would allow the shaft to have a protruding flange on the end to trap the handle)? Or step the end of the shaft and braze or silver solder it into a hole in the handle? Each of those will, I think, add to the possibilities for workholding of the body of the handle.
As with most things requiring machining in more than one plane, this is an interesting workholding challenge. When you buy a hand-held wood router, the snag is the array of cutters you will need. When you buy a CNC machine you need some cutters, but the challenge is in the workholding. Sometimes, it is easier to use manual multi-setups the same as on a manual mill or lathe. But that's not really the point of an exercise like this, because its about rethinking the possibilities. It hurts the brain but produces new neural pathways...or, as a visual artist would say 'new ways of seeing'. Great fun.
