Re: Questions about crab/swerve drive.
I seen the mcmaster one's but didn't even look at the size after i seen they were over the 1 item can be no more than cost factor.
Idealy you would want a through bore type i think so that you could do the coaxial setup with it. And If I'm right about the US Digital encoders they are a 4 conductor.
So anyone know where to get a 1/2" ID through bore 4 conductor slip ring and keep the cost down on it. Most of the ones i've found searching show them being able to handle RPM's in the hundreds which would never happen.
