I found another couple of battery drills being thrown out last week. One Power Devil and one McKeller.

The Power Devil is the usual bottom-rung battery drill, though looks like it’s been fitted with a replacement chuck.

I opened up the battery pack, and it was pretty much what I expected.

Mostly empty.

The McKeller on the other hand was much nicer and more powerful. However neither drill had a charger unit, so they’ve both been stripped down to motor and gearbox. I’m thinking they could be good for making a reasonably powerful robot arm.

The chucks on all of them attach with a 24tpi UNF thread. I might have to belt-gear them down, but then again PWM control would probably be fine and simpler to attach.

The little Unimat 3 circular saw just made a *bampf* noise and stopped. The fuses are still good, and the breakers haven’t tripped.

I think the motor just blew.

This is troublesome.

Just a little something recorded with the new digital camera. The one that you get the video off via USB.
