The original Marlin Roadster doors are pretty small due to the position of the running boards. But as I am going for cycle wings I thought I would take advantage of the extra depth. So I have removed the frame that the doors shut on. The picture shows a mock up of the new door with much better access. Should be much easier to get in now I am not quite so flexible as I used to be lol. I still have to add something for the door to close against at the bottom.
The original doors are basically a lump of 25mm ply skinned in aluminium. I plan to do something similar with the new doors although I will probably make the plywood more of a frame to keep the weight down. In my drive for a bit more safety I am planning to use anti-burst door catches from the series 3 Land Rover, as also used by Morgan. (Thanks to Peter for the suggestion.) More pictures once the catch arrives and I have made the first door....
