(...) He probably means two clutch gears in a single axle, meshing with two other gears which also share an axle. That way (in parallel) they should slip at twice the nominal torque. (16 years ago, 18-Apr-09, to lugnet.technic)

(...) That's not a bug- it's a feature. The point is to protect the motor from damage. That said, I bet if you used two clutch gears you'll get twice the allowable torque. I don't recommend it- but you could try it and see what you think. (16 years ago, 17-Apr-09, to lugnet.technic)

(...) With the PF and NXT motors, i perhaps agree with you. Of course, you can get any torque limit you want by gearing up and then back down, it's just more awkward. (16 years ago, 16-Apr-09, to lugnet.technic)

(...) I think it's a non-issue for the most part. The torque isn't really "over a range" - it's different for different clutch gears, but for any *single* clutch gear it's pretty constant. After all, if it has a point at which it starts slipping, it (...) (16 years ago, 16-Apr-09, to lugnet.technic)

While the worm and 1x4 rack pitch are not the same and they do not mesh perfectly, it is still possible to make them work together in a reliable way. You may see one example below, (URL) Originally posted at TechnicBRICKs (URL) (16 years ago, 7-Apr-09, to lugnet.technic, FTX)
