Your motor link shows that (i think that's not a good price for this motor):

Price: 899.00$ FREE Delivery...

;) SG

That's 899 Rupees, which corresponds to ca. 13 US$. I doubt they offer free delivery outside of India, though. :) Searching for the details given in the amazon description should turn up suitable RS775 motors elsewhere.

What is the drive screw called in the chuck and/or where can they be purchased?

Very cool, I'd love to try it! Any way you could provide the details/links to the PCB, on/off switch, and hanger/dowel screw?

Neat project! although I have to say the music on the video becomes painfully annoying after about the first 30 seconds ;)

Do you have a Bill Of Materials? I am not sure how long the 20X20 extrusions are and am looking for the size of the smooth rod. Also, what size are the nuts and bolts (although that I SHOULD be able to figure out...even if I'm not as able as I should be).Thanks!

The 20x20 extrusion lengths are not static, you can make them as short or long as your want (within reason). The same goes for the smooth rod. The mounting hardware should match the t-nuts that fit your 20x20 extrusions.

is that a 540 size motor?

It is a RS 775 motor.

I would suggest if you're going to be using the same size stock for turning that you'd want to lower the tool rest a little bit. The bevel on your cutting tool should be in the center, it's too high in the video. A slightly lower tool rest will let you have a better cutting angle, going in from the top is asking for kickback or massive chipping. Pretty neat design though!

Could you hypothetical build the base out of a piece of Plywood or something?

I would say yes just looking at it. Just screw down through the mount holes into a piece of wood or something solid.
