90 deg drive

[FlyingBeagle]

I dont know how big of a right angle drive you need, this may be too big, but I bet it would never fail on you.
I know a lot of guys over here buy cheap chinese knock off right angle drills and angle grinders just for the purpose of stealing the gearboxes. I dont know if you guys have anything like Harbor Freight, but I signed up for their email list and I am constantly getting coupons for 20% off and more sometimes on top of the sale prices.
