Found a machine shop on my way to work, if I can get the shaft welded and turned there for less than $100, I'll do that. If not I'll have to do it myself. That's my next step, put this motor together.
There's much that can be done with just a drill press, providing that the chuck is large enough.
It's not exactly the easiest way to go, but it is possible to drill a pocket hole into each piece that needs to be joined. A tight fitting pin is inserted into these holes which will align the two halves for welding. Be sure to chamfer the ends to be joined for better weld penetration and also, it will keep the weld from protruding too much beyond the surface of the shaft... then it's just a matter of using a hand-held grinder to smooth-out the weld, which is done while the shaft is spinning on the drill press.
You'll need to fashion some sort of jig for the grinder and fit it to the column of the drill press, which will give you greater precision when grinding the weld.
There's much that can be done with a cheap drill press that will mimic lathe work.
I suspect, that if Canadian machinists are like their American counterpart, once you tell the story of your experimentation, they'll give you a break and will do the work for 40 to 50 dollars. That's one thing about dumpster diving... you can't dumpster-dive for a machinist.
