help in forming roof
Posted: Thu Feb 01, 2018 8:48 am
Hello,
I'm looking at forming a roof for my boxcab electric in 1" scale ride on railroading.
I've attached the following diagram. I have several thoughts on how to do this.
I will say that I am OK with having ribs welded to the roof, for structure/rigidity.
For that reason, one option is to calculate the arc length of the 30 inch radius, then position my 3/4" radii accordingly. Then form/force the roof to the ribs, and tack weld them in place. This might be something I can do with minimal tooling. Perhaps a piece of bar clamped to the table.
I'm not sure what my other options are, yet. Thoughts? I have access to a sheet metal brake if needed.
Thanks,
Mike Walsh
