Hey folks,
I have a basic 3D printer, and a desire to spend my money buying coaches and DMUs from Worsley Works, and not on buying donor vehicles for inflated prices on ebay...
I have in mind to 3D print a jig matching the vehicle's roof profile, and use it to accurately and consistently shape a piece of brass sheet into the correct profile to form the roof. The roof could then be reinforced and further held in place with a 3D-printed ribs and spine glued underneath. Since no 3D printed part is visible on the finished model, the surface quality of the print should be less critical.
Has anyone experimented with this approach before? The only thing I could find about 3D printed jigs was an American modeller printing a jig for hand-built turnouts.
