This design is obsolete. I have a new updated version here:

This is a bracket and a few pulleys that you can use to motorize your ifootage shark slider http://goo.gl/ACu7xH (amazon link for slider)
You will need a 50 tooth belt that costs about 6 bucks on amazon, I got a few of these : Gates 100XL037 PowerGrip Timing Belt, Extra Light, 1/5" Pitch, 3/8" Width, 50 Teeth, 10" Pitch Length.
