Are you saying two wingnuts on the same axle? They'll both travel in the same direction. Unless you mean one nut on each axle? Which would be useless, as unless you adjusted them perfectly, one would not actually do the stopping.x_SOninja_x wrote:you could just put two nuts on the winged axle.
as they spin, they should travel in towards each other.
eventually, the nuts will get so tightly wound, that the threaded axle won't be able to move anymore, and the vehicle will stop.
Somehow I don't think you'll get accuracy from a rubber band. It's going to move around and the wingnut will move a different distance each time. Much better to use something solid. Generally the frame of the vehicle, where the axle passes through, is a good stopping point.or here's an even easier idea.
wound a rubber band tightly around a part of the threaded axle.
then get the nut on the threaded axle (position depends on distance that should be traveled)
and then have the axle spin until the nut is blocked by the rubber band.
i hope someone understood that.
Either way, you're going to be mechanically stopped but the motor will still be running, or attempting to run. That's not going to be good for the motor or any attachments, as it's still going to be trying to turn.
