I just dug out an old test car I made some years ago as I was laying some track and thought I'd show it to the world. Okay, it's not too pretty but it does the job. In fact, I took it down to a train club once where everyone had a good laugh untill they saw how it showed all the imperfections in the trackwork!
The first photo shows the car going around a new curve on a grade.
The dial on top rests on a third truck that is weighted and passes thru slots cut in the car. The slots allow the shaft to travel one side to another, showing slight varients in track work. Usually there is grid paper under the dial to show where the curve needs tweeking. The car also has tuned trucks with IM wheelsets for a nice smooth ride.
The second photo has one of the side plates removed to show the third truck. A look at the double ended level above shows a two percent grade, the first line being zero and last being four percent.
The last photo shows the level and the position of the dial. Like I said, nothing pretty, won't win any awards... but hey it works great!
I was planning to do another unit with working lasers on a buggy someday, maybe this winter? Well, let's finish the trackwork first!
