Definitely true Eric, every model is unique and would require it's own version. Ask Mario, even making the Kadee mounting shims..... there is no one size fits all. Everytime I buy a new Atlas car, the floor is different, or the thickness required has changed.

Very, very nice work. I will definitely be interested in your SD90 project; I've got one awaiting the treatment, but only so much time. Trust me, I agree with Doug, about the variations in doing these things, but on the other hand, some MTH models use common pilots (for example the SD90, SD60 and SD70s all seem to use the same pilot), so I expect that parts like these will ease the job. And those are very nice parts.

Yeah, there are a lot of ways to get it wrong and end up with something ugly or useless, that's for sure. To be honest, it's not so much managing multiple configurations of the parts that worries me (within reason, lol). If, for example, an Atlas chassis is 0.050" lower than an MTH chassis, that's pretty easy. The trick is getting all the measurements in the first place - that's the real key to having everything fit and work well in the end.

I think what might work is if I put together a more general model of the things, for starters. Then I can throw a drawing up here with the critical dimensions needed from the chassis. If the interested parties take that drawing and mark it up with measurements of their units, along with some pics, parts diagrams, and whatever else for reference, we might be able to make that work.
