Brings tears to the eyes that kind of commitment.. I have seen plenty of nicer shells get trashed. On the subject of spot welding you can do a fairly good spot weld with a Mig welder with a bit of practice. IN fact there are tip shields designed for the job and the flasher welders have a spot timer build in to set the arc length time. Drilling a hole thru one panel thickness helps wih the smaller low amp machines.

Anyway, enjoy

With one of these, you could really do a number on all accessable seams like the racers do, & stiffen up any possible sucpect part of the body.
It's good to see someone doing the whole thing right,... right fron the start.
I liked the 'action shot' with various coloured sparks flying too, & i just LOVED the callendar.

Edit. I just realised, i can see the front sheet metal & the chassis rails, but where is the rest of the body, or are you building one car from two or more bodies?

WOW, thats keen!
