Instead of a right angle drive, how about a light duty T-drive?

Most people use a portable right angle drill drive to get into tight areas. Having a T defeats that. Perhaps if you told us what you were really trying to do it might get you better suggestions. A shaft ending with a 45 deg gear driving a second shaft that goes both ways with a 45 deg gear on it is not unheard of. Some simple self propelled equipment often has something like that.

Don't know how much torque he needs, but I've found this little guy *very* useful.

That looks handy but he's after something like a traditional car rear axle only smaller. I'm not sure his purpose is drilling at all.

Absolutely great!

Maybe he's trying to build powered roller skates.

There's a cordless out there that has swivel head on it that will run at any angle between straight inline and 90 degrees. Don't remember the brand, but seemed kind of bulky compared with the pneumatic. Usually, if you need a right-angle drill, the space you'll have is just a fraction less than the drill head.

Yes, some of Dufas reference looks very close.

I really like that, but (assuming it is strong enough) now I need to figure out how to rigidly connect the keyway shaft to a skate or a larger scooter wheel (same inner diameter). Some spacer has to slip onto the keyway shaft and fit into the scooter wheel (without bearings). If only I were craftsman...

FWIW.

Fascinating IMO, but probably not until motor and battery weight decreases with high technology. Making in-line skates cumbersome nukes their function. The gasoline engine stuff is garbage IMO.

Similar is a push stick for in-line skating. The closest thing is probably a bicycle pusher as seen on YouTube (mostly gasoline). A lithium-ion electric Trikke "Pon-e" is almost made-to-order (for

There is a drill attachment like that sold by McMaster, maybe the same as Milescraft 1300 Orbiter sold elsewhere.
