To do these parts easily and cost-effectively, a mill, a lathe, some fixturing (you will need to fabricate jigs to hold the parts for easy parts changing), and a lathe with a couple of different chucks would be useful. I have had no luck using a drill press for much of anything fine like this, either I get broken bits, holes that aren't centered, or that sort of thing. A lathe with a 4-jaw is what you need for that to get a pro result (as was mentioned earlier). Part of getting that is facing off the end properly.

If you have a mill with either digital readouts, CNC control, or a quality indexing head or rotary table you could be in the capsule backplate making business too...

A local machine shop is almost certainly going to be cheaper than emachineshop, and if they are doing less than 20 parts they may well do them on manual machines. Make sure you tolerance the drawings, though.

You better believe it! I got quotes for the bodies themselves from emachineshop and from two machine shops near my home... emachineshop wanted about $65 per body, while the other two places quoted me about $45!

45 bucks is still a little on the pricey side for a piece of brass pipe with two square cutouts, though... I'd rather use the dremel-and-file method.

Come Monday, I'll call a bunch of machine shops and get quotes...

Peace,
Al.
