Made some tests for roll cage design, only mock ups using solder wire and tape. The design will change but it helps gets the ideas coming and refining. Can't start the rear part yet since the wheel tubs are not there, and the tubs top part is where all the back tubes meet.
Front doors will have X and not just one diagonal, but did not bother for now. My reference pics are google search for group-4 escort mk2
I have received the brass tubes for the cage this week so that pushed me starting the design a bit
The solder wire is a bit smaller than the brass tubes which are 4mm but it still ok for design, easy to bend to shape. I made new calculation since I thought maybe 4mm was too small, but the wheelbase scales at 1:9.57, so the 4mm tubes scales perfect for the 38mm tube dimension I was targeting (38.28 mm). Though I just read sometimes the main hoop is 45mm.. but I guess I'll be fine
