peg leg

I've now managed to adjust the mill in a satisfactory manner. Not perfect, but adequate to task for the time being.

Started in on the current project; it's for an MV Agusta F4. I need to fit the footpeg from a 750cc model to a 1000cc model (again, don't ask). The 750 peg is wider, so it has to be milled down on either side. Trouble is, it's shaped like a banana. Coming up with a safe way to hold it during milling was interesting. I thought of a dozen bizarre and overly complicated approaches until finally settling on this:


It seems so simple in retrospect.

Cuts were .005" per pass, and the material came off in little shavings, but floated around like powder. Had to take a little over .030" off each side. Not sure what the alloying elements are, except that I was assured "no magnesium". The thinned 'peg fit nicely into the intended bracket width, except that the inboard radius is too large to admit the pin:


Must now mount the rotary table (finally, an excuse to use it) and come up with another, hopefully elegant, way to hold the 'peg securely while reducing the radius. Only the simple fabrication of a pin remains after that.
