Trying to find a technique or information on scaling up from a 1/18 diecast model of a car to make a life size car body. How to make the”buck” or “plug” then the “mould” and finally the body
That would be difficult. Many scale models will “cut corners” to make a cost effective product. Plus, the error factor on the size of the panels would increase. A panel which measures 0.10 ft and +/- error of 0.01 ft would be 0.10 x 18 +/- 0.01 x 18 error. You would be better off trying to find blueprints or schematics of the original vehicle.
