disassembled four of them now. 3 of them i cant turn by hand but 1 i can? does this mean theres something wrong with this individual motor/gearbox unit?

Re: £10 argos drills

Can someone please talk me through the grub screw method? I understand the threading , etc but I'm confused as to how deep the screws are going and if they are meant to touch the notches on the ring or the ring itself? I tried the o ring and it snapped one of the bolt holes on the motor mounting!

Re: £10 argos drills

The grub screws sit in the notches.

Re: £10 argos drills

As in between the raised points on the ring gear? So it basically stops the whole ring gear rotating yeah?

Re: £10 argos drills

correct 2 per motor is best don't go to far otherwise you will lock up the gearbox

Re: £10 argos drills

Would you say putting the screws either adjacent or opposite is best?
