*--- UPDATE ----*
It's been a few months since settling into the new space and I finally was able to devote more time to my little project. It has grown quite a bit and I do mean quite. What started as a simple precursor to a half track is now something far bigger. Read on
Some years ago, I had some scrap aircraft aluminum that I was using to practice riveting techniques with. As I got to drilling and countersinking, I realized that if I am going to be drilling holes and putting in fasteners, it might as well be for something more than just some scrap bits and pieces. My scrap aluminum became a Go Kart and it went very well. With some Home Depot materials and stuff lying around my garage, I cobbled together a 2 seater that at half throttle was clocked at 15mph. Since then, I moved twice and the Go Kart is gone....well, the frame is. But the engine, wheels and transmission (a Torque-A-Verter torque converter) are still here. This project started out as a prelude to building a 4x6 Go Kart/ATV/Replica mini APV (I have these huge ATV wheels to play with), I went puttering around the Internet and found the plans from SpiderCarts (www.spidercarts.com
) and what intrigued me most was their 3 wheeler. Looked around my shop and lo! I have wheels, sprockets, bearings, chains, tons of nuts and bolts, cables.....Now if I can make the same kind of thing but NOT weld a darn thing....
As I got to work and I assembled my frame, I found that the use of a single back wheel posed some problems with the parts I have. Specifically, my rules were that I was not to use (or try real hard to not use) anything I did not already have, and if I needed it and couldn't make it, then and only then could I go buy it. In this case, the problem was the brake. I had these lovely disc brakes, but they were meant for a 1" shaft and they were meant to not mount to a wheel. After much trying, I found that the brake calipers just would not accomodate this concept, so I shifted gears. The first few steps take you up to the point when I realized my problem, and then I continue with the resultant design. Here's the thing though: the drive system as I have completed it allows my MMV to be a 2x6, a 4x6 a half track and by locking the steering, a tank, or a 4x6 skid steer. So follow along won't you?
As you might imagine then, this is a work in progress.
