Thanks for the info. The repairs are to rusted areas that have been
completely cut out. The welds do not have to be ground flush but I
assume if the new steel was flush with the old it be both neater and
stronger. How do you hold the new metal in place, also stopping it
from falling inside the chassis - while you weld it.

Thanks again

There are a variety of clamps & tools for this but the cheapest way is to
tack weld a piece of scrap metal onto the piece to hold it with then tack
weld it in place. It helps to have an auto welding mask or a helper at this
point. Since you are working on a chassis, the finished job doesn't have to
be beautiful, that makes the job easier.
Try a search for car (auto) restoration for a whole load of info on this
subject.
When you say the rust has been cut out, I bet it hasn't. You will almost
certainly find the original metal is very thin when you begin to weld to it.
Good luck.

John

Thanks for the suggestions
