The stepper that came on the Rino is a 166 oz-in NEMA-23 motor, but with 30:1 reduction / torque multiplication, I think a NEMA-17 motor could do the job. It has an 8mm keyed shaft, and a couple rings with grub screws keep the shaft from sliding out of the gear box. I am running the motor at 1A, driven directly by the smoothieboard, and it doesn't even get warm.
Here's the Rino I bought- looks like he is still selling them: [www.ebay.com]
Here's the data sheet: [www.ondrivesus.com] These are the PF30-30ANM parts on page 3.
I don't know why he doesn't have the word "Ondrives" in the title somewhere- I was looking at these things on ebay for a couple weeks before I found his listing. "Rino" is used for a lot of different products.
This guy sells the shafts: [www.ebay.com]
I asked him to make me an extra long one (I could have done it at the makerspace, but I don't know that it would have been cheaper by the time I acquired the shaft and key stock, tools, etc.). IRIC I paid him $20 or 25 to make the longer shaft.
My measurements of belt stretch include the shaft torsion, of course. I put the motor at the middle of the shaft so the torsion would be equal at both belts.

Why make a 3D printer then ? just put an extruder/hotend (or even a plasma torch) in the chuck and a heated bed on the mill table "et voila" !Quote

hah! Making chips is fun. Too bad the tools don't make the printer.
