Portable cordless drill press

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!

Gui,
The pictured drill press above with the Dremmel works OK for very small diameter drill. As you increase the size of the bit the speed must go down and the power(torque) must rise. The speed is in the 100's for RPM not the 1000's so a reduction of the shaft speed is needed without reducing the electrical input to the CIM. We all know that the CIM is pretty powerful so a gear reduction should work fairly well.
On the controller, I can't give you a good answer on whether it will work at 12 volts. The components are price sensitive as to voltage breakdown and when you are making a run of 1 million, a few cents makes all the difference. A low voltage part may have been used. It will take some research to find the part number and then the breakdown.
