I like the job my buddy does with the tig welder.
Another friend of mine has built a lot of race cars - and is building
one now with an aluminum chassis (a "clone" of a Lotus 7 - not an
abomination like a Locost, but actually to accurate lotus 7
dimensions, modified to make out of aluminum angle, and running a V
twin bike engine.) It is ALL being rivetted, as he says with welded
6061T6, unless you can re-heat-treat it (which is NOT a do-it-yourself
job) you have no idea WHAT you have after welding. So, he's building
it according to "aircraft standards" - all joints rivetted and
gussetted.

Does he have anything online about this? I'm curious about how he modified
the 7 chassis so it could be made out of angle.

Nothing online, and it has not been proven yet - but this guy has
repaired, rebuilt, and reproduced more sevens over the years than
likely anyone else in Canada. He's got all the jigs.

The "angle seven" is being built by his son, actually, (with Dad's
help) for one of the "formula grassroots" type races - something like
Formula 2005? where you get to spend up to $2005 US to build a car and
then race it.
He expects to also drive it on the street.

The seven is built mostly of square steel tubing (mild steel at that)
- much of it 1" square.

The "Angle Seven" is made of 6061T6 or 6061T651 1 1/2 inch (I think)
angle and will have the driveshaft tube fully triagulated into the
front bulkhead.

He estimates the material cost for the chassis, with some carefull
scrounging, to be about $200 Canadian plus rivets. Mostly stainless
steel Pop rivets
