Rolling a roof
Posted: Mon Jan 13, 2020 11:49 am
Can any of you experienced carriage builders help with a question of technique for rolling a roof?
I am scratchbuilding a small boxcab diesel in P87. It has a three-arc roof profile, with tight curves down to 2.7mm radius at the gutters. The bodywork and roof have been etched in 0.3mm nickel silver, with the roof being half etched to create the beading around the edges and the lines of rivet detail. That means that the majority of the roof area is around 0.15mm thick.
I had assumed that the initial roll should be at the larger radius (around 33mm), but creating the tighter curves at the edges would seem to be beyond the scope of the rollers.
Does anyone have any bright ideas as to how I should do these please?
Many thanks,
Geraint
