thanks Travis, I was going to make the block that travels the screwdrive with a couple of different mounting points. I understand why it has to be lower at the screwdrive, so it pushes up instead of wanting to just push it forward. Again thanks alot for the advice I need as much as I can get due to not ever building one of these before.

I do have a question about the motor that drives the lift arm. Do I have to install limit switches to stop it in the full up and one for the down position? If so how do you wire them into the motor/ speed control?? Or do I just use a 3 position switch on the remote??
