Axle Flanges

The plans call for a piece of 1-1/4 x 0.120 tubing 10 inches long to be welded to the "V" at the bottom of the gear legs to be used as an axle. While I probably could have made this work with my wheels, Matco actually recommends using their axles. They're made from lightweight aluminum and already have the brake mounting spacer built in. The problem is that these axles bolt onto a flange instead of being welded. So after buying the axle tubing and discovering that it wouldn't fit my wheels without some machining anyway, I decided to go with Matco's recommendation. Although these look like engine mount "spools", they're a bit bigger. The tubing is 1 inch x 0.065, 3 inches long, and the flange is 1/8 inch thick and 2-3/4 in diameter. Using Matco's axles will give me another advantage, too. Since they are bolted on, it allows me to use shims to correct any wheel alignment issues I might encounter. With the factory-specified welded axles, I'd have to live with any misalignment.
