A bit of a How To on making van roofs removable. With some scrap etch mark it and cut it to the profile of the roof Once you have as many as you need - in this particular case (an ex GCR CCT) I needed three but usually you only need two. Clip them to each end Then solder some strips of scrap etch in between them to create a framework that sits inside the ends. Bend your roof to shape Then solder the frame to the underside of the roof and you have a roof that's removable. You will note that I added a strip at each end and in the middle where the former was going to fit? This was because the roof appeared much thicker in the photo that I was using so I beefed it up a bit.
