1. Try to machine a groove in your idler wheels to keep the track in.

2. We made small guides to keep the treads aligned. They are pretty simple.
We used lexan as a plate, and the cantilevered 2" long bolts (like #10's) from them, with metal sleeves over the bolts to act as "rollers" for alignment.
We have one set placed at the front and back of the drives.

These roller guides are spaced just a little bit wider than our track so there is not much friction. The bolts and sleeves came from Home Depot so they should be easy to find.

If the description doesn't make sense - PM me with an email contact and I will try and send a power point picture.
