This is a lathe project that tests the limits of a 36" swing lathe. What I needed to do was to change the guage of some wheels that were originally on a Drott 80R so that they would work on an Allis Chalmers TL 30. We have junked some of the Drotts but kept the tires.

The project was fairly straight forward. The bolt circle that mounted the tires was such that it would bolt on the TL-30, but because the tires were wider by a few inches, the wheel gage was such that there wasn't tire clearance, so it was necessary to cut the weld out that held the bolt circle in the wheel and reweld it establishing a wider gage. This is not technically complex other than you need a large lathe (big and strong enough) to hold the the wheel and a boring bar. As the wheels are about 30 inches long and weight several hundred pounds, I chose to not only hold them in position with the chuck jaws but also bolt them to the chuck. The internal bolts were the most sure fire. Using T nuts in the slots on the chuck and 3/4" bolts through the lug bolt holes, the wheel couldn't go anywhere. With those bolts slightly loose, it was actually pretty easy to center the wheel as you could take the chuck jaws loose and retightning them would slide the wheel around on the face of the chuck.
