The printer has finally printed off the fourth of the four coach body parts and is now rattling off the end sections with the steps and corridors.
I have some Tenmille bogies which I was going to put underneath it on the basis they're GWR too, and the only things I have to hand.
I need to canvas suggestions for the chassis and roof though. Particularly the roof.
Printing this part off just isn't worth it - it's the most obvious part, takes ages to print as it's huge. More so at a very high resolution in order to keep it smooth and well detailed.
Given the shape, I think some balsa or styrene sheet over some formers might be a better approach; certainly a better end result and without days of printing. I can then add detail such as vents and rain strips.
I've scaled some roof formers to accept a 2mm sheet and am wondering which would be best? I'm leaning towards styrene as it'll be more durable I think and require no sealing?
As regards the chassis...maybe 2mm ali plate to epoxy the body sections to, to provide some weight and to allow underside details and the bogies to be attached to?
There are brighter minds than mine on here and having been so close to it, I'd welcome some fresh ideas and a sanity check
