2003 Drill Motors Good or Bad?

And if I remember correctly, beryllium can be used to make extremely strong and light alloys of aluminum, at a relatively small cost compared to making other alloys. And it isn't radioactive.

So that's why they made Beryllium illegal... I'd been wondering why anyone would want to use it. It makes sense, I suppose.

Teams want more drill motors because they are very easy to mount compared to the Atwoods, they have a shaft that can easily be coupled to another shaft with gears/sprockets on it, and they can be shifted with fairly little fabrication of other parts

I'll give you the shifting but I find the other two points rather untrue. The Chia can be mounted to a 3x3 angle (or other vertical member or plate) with two 10-24 machine screws and 3/4 clearance hole for the projection in the center of the faceplate of the motor. As for adaptation, with the provided couplers the Chia was just as easy to adapt this year as the drill (2002 was hard though).

A couple more points in favor of the drill and gearbox:
It can often be used with only a single stage reduction (using the Bosch gearbox). The Chia requires a lot more reduction since it doesn't have a gearbox already. Another thing is, this year's drills were more powerful than the Chias in terms of wattage.
