Dean,
If you can TIG or
have access would be the best, less heat with less distortion. Plus, you can
find some good how-to-videos on Youtube and
others.

sheet metal
Dean,
I would not braze;
its twice the work and heat input.
A good mig weld is
not porous. A lot of welding mishap occurs due
to:
--corrosion or scale
on material or wire
- Water and/or grease
on material or wire
-dirty or leaking
pistol/hose
-wrong gas (should be
CO2 with 20% Agon 8 litres/minute)
I experienced with
welding the KSS that the half finished hull acts like a funnel. The created
airstream blows the gas away!.
Good luck,
Emile
