OK, platform and all that aside, how long until your prototype front dash is operational? Are you willing to go that extra mile for the side panels, specifically the left side, or radio side? Both sides would be worth every penny as most people including myself, cannot fathom the wiring required for any U.I. let alone a simulated radio stack. I would like to jump on that bandwagon first and request directions to your thread as to invest and request.
I must assume that any form of metal would be just too cumbersome. The best results I have seen for any fairly inexpensive control panel (from N Scale R.R. to F-15) turns out to be plexiglass of appropriate thickness' and the triple throw, double pole switches or whatever is needed. The later is procured at the electronics shaq and the plexiglass from most hardware stores. The use of spray paint on the back makes for a great reflective, colored (or mostly gloss black) surface. The perforations can be made without cracking the material. It can be cut to the proper angles. Adhesives are legion and the thin plastic cover is removed by the end user for that "shiny, new" look. Dont forget the adjustable backlighting to illuminate the reverse stenciled instructions for each switch (never fades as it is never touched).
In closing, let me know what your schedule looks like for the prototype. I would be happy to invest in your idea, but only to net as many pieces of a replica pit as possible. Not as a bussiness investment. I believe that it is such a niche market that the time and talent brought together just for completion would push the price through the roof. Not to mention any expressed or implied warranty. I do however wish you many fulfilled orders and no returns.
As a final note, I could REALLY use a set of covers... wife may just stitch them out of an old A.L.I.C.E., but I would love the logo or monogram and I don't care about the "Tag". It is a clincher for some, but I just need to keep the Maui silt and burned cane out of my throttle quadrant.
