EDIT: I don't really have room for a manual mill which would be large enough for this sort of thing to make the parts I want(the Grizzly would be really pushing its limits).

It's more idle speculation at this point in time --- I did save the electric motor from replacing the garbage disposal recently (cracked housing) and I also have a key duplicator I fished out of a dumpster (working!) and really, it should be workable to fabricate something given the tools I have.

If you did a writeup on making a lathe w/ 8020 profiles and a cartridge spindle (source?) I'd be interested --- what would the total landed cost be?
