There are a lot of knowledgeable folk out there and sometimes a quick question before diving in can avoid expensive mistakes...
My background is mainly digital electronics and PICs, I've always liked stuff that moves on its own so CNC hits all the right notes for me.
Hell of a learning curve tho, machining seems to have centuries of occult wisdom behind it and despite lurking and reading for probably thousands of hours I know I've barely scratched the surface.
Fun times ahead!
Irving; the motors I got are MY103H702 NEMA 23 about 160 oz/in.
Not great but my budget is microscopic. I got 4 for £35 + delivery.
Im knocking up some 3977 based drivers for them, got the chips free as samples.
Im going to use 2 motors for the main axis and one each for the others.
Marchant Dice trap. thread is cheap but their machining costs are crippling; looks like threaded rod till I can afford something proper.
When I start doing something constructive I'll take photos and start a thread - still got parts to scrounge.

Same motors i have, but i paid a tad more... it was £30 for ages then some b****r dropped a bid in at the last second and pushed it to £60 if memory serves.

I'm sure there'll be someone here who could machine the rod for you for some beer tokens. I would offer but my lathe not sorted enough to do my own yet!
