Can’t believe I didn’t think of that! Was lying bed last night thinking about getting a bigger fan. Oh well, better welds or better lungs? Perhaps I’ll just be sensible and allow the fumes to clear before looking at the weld!
You can build the whole car with a handful of timber shapes and a light hammer, that's how coachbuilders worked. We do similar work building race cars, customising panels in the simplest method.
It will be a work of art when the car is finished!
