PP housings
#1
I finally finished up a jig to hold rotor housings on my milling machine so I can do PP housings. Machined a junk 12a housing tonight just to test it all out. Came out rather well, although more time consuming than I expected. These housings are pretty tough for aluminum.

Yes, but not only that. Jigs need to be strong, even moreso when they will be used a lot, like production work. It also needs to be strong so it doesnt lose tolerances as its used. Milling machines can put significant side loads on parts being machined, and I need this jig to be as rigid as possible to get a smooth, clean, and repeatable cut in the housings, and to continue to have those qualities for as long as I use it.
FYI, the jig was CNC cut via waterjet, assembled and welded together. The jig alone weighs 40-50 lbs.
