Hi I am planning to build a 2 seater coupe from scratch, mainly from Aluminium. I am just starting, as a designer and car lover the design part was not the biggest problem (I actually have it "build" in 3D in the computer, but now the hard part, actually building it The body I will probably build completely from fiberglass I just bought a 90amp mig welder but have no experience I want to start with the space frame chassis, any tips on how to start (which part first to avoid twisted parts...)??? Some questions What will be the best approach? -tubular or square tubes? -tube thickness? -what to use as a base so the construction will actually get out straight and strong? anybody has experience building cars / frames???
