Ok Joe,
Here is how I'm doing my linear motion. The timing belt is anchored inside the slot, then rides up on the delrin rollers up to the pinion gear. It's about the cheapest form of linear motion I could find and has no noticeable backlash or play. I'm very happy with it. The back side just has two more rollers to act as guides.
