And a closer view.

After cutting the drive and idler wheels on a band saw and boring them out on the drill press I found that the wheels weren't perfectly true. So I made up this jig to true the idler and drive wheels to their shafts. The jig holds a shaft, and thus, the wheel parallel to the saw blade. The blade is raised about an 1/8" at a time into the piece which is then rotated around 360 degrees. Keep doing this until your done. Works great!

How I clamped the wheel jig to the tablesaw.

I made rubber friction belts out of rubber bungee cords. The ends were cut at an angle (scarph joint) and glued with Goop brand cement. I used brads and more Goop to attach the rubber to the drive wheels. We'll see how well the glue holds up after a few Tiger hunts!

Here's a close-up of my drive and idler wheels. I used the nylon spacers shown on the bottom as bushings for the wheels. The idler has two bushings and I used four in the drive wheels. They seem to work well but we'll see how they hold up after a season of battling.

This is a piece of prototype track that I built a while back with an idler on top of it. My track system consists of belting (treadmill belt) with inner and outer maple track pieces. Alternating inner pieces have those teeth that keep the track on the wheels, just like on the original T34. The wood is glued to the belt and then everything is through nailed (tell the wife air nailers and a compressor make for a great Christmas gift!).

30 year old seasoned Rock Maple in the form of an old butcher block that I saved from a kitchen remodel job. I'm making my tracks out of this.

Tablesaw! Another great gift idea! If your looking for a tablesaw in the $500 range, I highly recommend the Jet brand of 10" contractor saw. Dollar for dollar you get a much better tool when compared to the Craftsman brand and it comes with a decent fence. It even comes with a sealed fan cooled motor unlike the open frame motors on Craftsman.

T5 needs 52 toothed track pieces. You first mill out the angled splines and track pieces. After you glue and nail them together you get these neat looking items.

Step two in making the toothed pieces. A miter saw is used to separate the pieces. The blade is set to 10 degrees.
