: The last thing finished, in conjunction with fellow builder Terry McCauley, were two 2-1/2 inch scale Gramps tank cars (see photo below). I have several other projects, and one worth mentioning is, again with Terry, an automatic wheel lathe. Started with an old automotive brake drum lathe. Added stepper motors and electronics to follow the [[Wheel Standard|IBLS wheel profile standard]]. Some of us Texas narrow gauge builders got together and made a generic 2-1/2 inch scale freight car wheel pattern and had a local cast iron foundry cast 100 wheel castings. Turning that many wheels is a daunting task. The automatic wheel lathe takes alot of the drudgery out of it. Process is face off the back of the casting on an engine lathe, drill and ream the axle hole, clean up the rim, face off the front of the casting, and turn the casting to final wheel thickness. Then it is put on the automatic wheel lathe for turning the tread profile and flange. The automatic wheel lathe can handle any wheel up to about 12" diameter and 3" thick. To date it has turned well over a hundred wheels. | : The last thing finished, in conjunction with fellow builder Terry McCauley, were two 2-1/2 inch scale Gramps tank cars (see photo below).

Tom Bee
Shows the usage of Tom Bee's custom designed wheel turning fixture that he built for use on a lathe many years ago. This is a one of a kind! It can be used for any diameter or width, having a 3/16" tall flange. This is only the demonstration, without an explanation. Published on Nov 5, 2012
