dont bother just buy grub screws instead

how would i go about locking the gear boxes with grub screws?

you know there are lots(like 10 or 12) of little holes round the top of your drill motor screw them in there

**mattsdragons** · 12th February 2011, 18:26

so you just screw them into all the little holes?

what size screws would i need for a argos drill motor?

**harry hills** · 12th February 2011, 18:27

mine were m6 i think. i only used 4 in each drill though

and did you see any improvment with drive etc?

o rings have more chance of slipping and degrading. Grub screws work well. I used m5 on mine. You tighten them until the output shaft doesn't rotate in your hands. Be careful that you don't go too far as you will start to push the body of the drill away from the front plate on the motor.

Well it gives you all the torque the drill can muster unlike an o-ring or the standard torque limiter which will slip under heavy load, good if you want to protect expensive components but not so good in a pushing match.
