Thread: Monster in Box HELP!! WIper motor connection

Tweet

Have a wiper motor to lift the lid, the problem I run into is the motor has a "threaded post" which does the spinning, what do you all use for a "shaft" to connect the motor with the cam??

Damn, Im stummped!!!

Check this pic of my tombstone popper. The flat aluminum bar connects to the crank arm provided with the motor. I used a 1/4-20 bolt with a stop nut (steel nut with a nylon insert) to attach the bar to the crank arm. The stop nut prevents the linkage from tightening or loosening itself when it moves. Another way to get the irregular motion would be to attach your cam directly to the motor shaft. Here's an example:
Cams and cam followers

Exactly what I needed!! WONDERFUL!! TKS OTAKU!!

I used a threaded rod coupler to extend the rod coming out of the motor and a small piece of copper pipe as a spacer between motor and cam.
