As promised, I have tried my idea and deemed it adequate for the job at hand. My I present my oh-so-clever 
solution:
Yes, that is a Harbor Freight special. 12v Warrior drill driver. Supposedly 550RPM max, but I don't believe it.
And while I'm not being serious, it is, in part, my solution. I will disassemble my brand new drill (which cost a whopping $14.99 on sale), and use the motor and planetary gearbox within to make my power feed. I also bought and tried the 18v version, which is faster and more powerful, but decided I could live with the slower speed because my power supply is 12v, and I didn't want to buy another one.
As shown, the 12v version moves the mill table from one extreme to the other in about 25 seconds. The 18v version did it in about 16 seconds.
I will now perform my motor-ectomy and figure out a way to mount that instead of the wiper motor. All the rest of the project will be as I started, unless I run into some problems.

Full of ideas, but slow to produce parts
