Working main gear alignment. I moved the Cleveland brake calipers to the rear now, so that I can run the brakelines directly down to them, The plane had extenders on it as received, and I removed those. The brake lines that were on the plane are abit longer to have reached the calipres with those mounted, so I will be able to run those lines directly down to the Cleveland's, and wont need a flex hose from what I can see.
I started off aligning the mains from the Cessna manuals, but through inputs from a number of very qualified sources, that wasn't going to be good enough. The better methods suggested were to drop a C/L from the fuse and align each wheel to that using the compound shims. So far I have the left main in pretty good shape, and am working the right main.
Pictures show the simple setup. It's an iterative process, and if I took some time I could probably work some math to guide the selection and orientation of the shims to achieve alignment faster, however it's good exercise to get up and down from the cold concrete slab of my shop (air is warm, floor is cold), I figure!
- A 3' length of alum angle is lightly clamped to each brake rotor. and the string tied to the jackstand touches plumb bobs dropped at the front and rear. Toe is measured to the string. Camber is measured with a race car bubble camber gauge.
