Improvised Power Drill

[Straightliner59]

I bought this power eraser a while back, in my eternal quest to find an easier way to create engine-turned finishes on aluminum sheet. It doesn't really work, for that, so...Today, I needed to drill some holes in the surface of the wing for my Supermodified. I saw the eraser, and thought about how I could make a high speed bit fit in the eraser. Three layers of heat-shrink tubing later, I had my holes! It's high speed, and low torque, which is ideal for this application. The low torque doesn't snap the bit, if it binds. I decided to keep these all together, 'cause this is now a "thing"!

That's pretty cool.   The best tools are the ones you make.

I took a slightly different approach to the same problem.  A power supply out of an old desktop computer, a DC motor with chuck and a variable speed control from Amazon.  About $20 tied up in the whole (hole?) thing.

How about hooking the motor up to a light dimmer switch?????....

May or may not work, depending on the type of motor.

Sorry the eraser didn't work for the engine turned panels. I am glad you found a use for it. The idea of not enough torque to break bits is a huge plus. The wing looks killer!

 Thanks, Mike! That low torque is what makes this so valuable. I have a Dremel with a flex shaft, and a mill. They both have too much torque. This thing, if a .5 mm bit catches, the motor stops!
