no if you just wrap it tightly around the terminals it should work fine

Don't just twist or wrap the wires. It works fine for temporary use, but it's probably going to slip apart on you at the most inopportune time.

If you're attaching to contacts on a component, either solder or get an appropriate sized crimp connector if possible. Some contacts are the correct size for crimp-on connectors, others are designed just to be soldered to.

Just food for thought. I know that iron can conduct electricity and threaded rods are made out of that (right?) So what if you made a same breaking system as scrambler and have a gap in the threaded rod so when it spins over to the other side of the gap it hits the braking wall and the motor stops I'll make a diagram and post it.

i have a feeling that would be hard to get to work right because you would have to make sure rhe axle cannot move making it so that it wouldn't finish the circuit
i feel it would be easier to just have a limit switch that gets activated when your wing nut locks to stop the axle but if you can get this system to work right i would love to see a picture or video

Yeah It'll be difficult but once you got it down i think it will be great! As for a limit switch I was also thinking about that. But wouldn't it be easier to have to flat pieces of metal to complete the circuit. (maybe a using a spring to keep them together) and then the wing nut will separate them after a certain distance? (is is that what a limit switch is??) I'm so clueless sometimes :?

this is a limit switch Image

you could make the arm wider/longer by gluing medal to it i guess

Oh thanks. My design won't really have any switches, except for the main power but that's bout it. Any other thoughts on how to shut off power or to cut the circuit?

And how are you possibly going to stop without switches then?

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.

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.
