If you get something figured out I'm sure you could get a nice list going of people who would jump on buying a ramp set from you, myself included! Most tmnt owners ramp sets are in pretty bad shape, someone else had started a thread about making some but it never happened. I purchased a reproduction pinbot light bar topper a couple of years ago and the results were great. The maker used vacuum form I believe. Another pinsider made and sold reproduction sof and space station ramps. If you get something going, I'd buy one from you.
