Portable cordless drill press

[Gui Cavalcanti]

In my engineering class, we've been assigned a final project, which is to invent something useful for your community. All we have to come up with is a semi-working prototype. Since most of the team members I know cannot drill a straight hole with a cordless drill for the life of them, I decided to make a cordless, portable drill press.

I'm making this from scratch, out of the remains of an old 6V drill of mine and a CIM. I have a couple of questions:

First, do you think that simply putting the chuck off of the drill directly on the output shaft of the CIM would do for a test model? The CIM would spin relatively fast for a drill, but it does have variable speed control, and it would not operate at no-load speed...

Secondly, I have the control components (squeeze trigger and directional control) from the 6V drill, but I was hoping to wire a 12V cordless drill battery through them to power the CIM. For the brief periods I'll be using this drill press for (very brief, just for 1-hole demos), do you think I need beefed-up components, or should the 6V components do?

Thanks!
