Just thought i'd string up the 360VM Crank slider with some 30LB Fishing line and see what type of movement I could achieve with a basic battery powered Rotisserie motor. There are some great examples of these rotisserie motors being used on DIY projects like this one here and here.

It might look like things are standing still, but if you look closely the carrier is slowly inching it's way across. These very slow speed rotisserie motors are great for simple motion control on a slider because they can probably pull a full sized turkey. To speed things up I could possibly add a larger spool. The larger diameter will pull the carrier down the rail at a much faster pace. Or if you're up to it, start looking into servos or motors and speed controllers like the one Gordon has used on his Konova.
