We had the idea to acquire some vehicle scales so that we could weigh coaches at rallies. Carl P. on the GMCnet suggested a build-it-yourself scale kit from here and Frank Condos volunteered to make them. Frank planned to use materials he had on hand so we didn't expect them to be perfect for this first-time trial. The photo on the left shows Frank ready to begin weighing coaches.

We did have some issues with the scales initially but with Manny Trovao's help and (relatively) nearby shop we got them fixed and weighed 31 coaches over a two day period. Below are our results. Everything is pretty much self-explanatory except the "X-factor" which is my try at looking at the theory that a heavy side in the front might be caused by a torsion bar on one side being mis-adjusted and causing the rear suspension on the opposite side to make up for it. The number is derived by subtracting the total of a front and it's opposite rear side total from the other front and it's opposite rear side total. Comments are welcome.

Below is a list of the coaches in the order in which they were weighed - some people were suspicious that the scales were not correct and that their particular weights were incorrect. While this is possible, coaches that were weighed later were OK so take it for what you will. Here is a down-loadable version of the Excel spreadsheet so you can see the raw data if you want to.
