I'd like to see custom molding services, similar to custom decals, where you provide basic CAD or drafted and dimensioned drawings for parts (say, like window castings) and an entrepenuerial CAD-CAMM operator with some sort of laser-prototyping machine generates the forms then casts your parts. Truthfully, all the technology is already there, but the machinery is expensive to own. Once a service like this became available, the library of detail parts available would skyrocket; I, for one, need high-nose bell mounts for my N-scale Norfolk & Western diesels. Once I draft up the basic form and have it produced (likely at not insignificant cost), the pattern or mold would exist for anyone else to order units as well, and computers & the internet are very good at keeping a comprehensive database of such unique items. <br /> <br />The only trouble is how to structure it financially, since the prototyping machine would be costy, and the volume of parts needed by any single client would be small. Perhaps a royalty structure would provide incentive, as the initial setup cost would be borne by the designer of the detail part, but then all future sales of that part would line the pockets of the original designer. Then we'd start seeing deisel shells with winterization hatches or modified grille arrangements or other minor prototype variations, all specific to a railroad or era, filling all the gaps in current production runs, not to mention how many other things you can think of that you wish you didn't have to scratchbuild. You could design your own custom building kit, even. <br /> <br />What else would I like to see? Norfolk & Western H-10 and H-2a hoppers in N-scale (with the right panel count and stake spacings) and N&W Class CG / CH / C2 cabeese in N-scale.
