Hi all,

Well I decided toweld my Series up on the chassis like some of you
suggested. I have used 3 mm plate and seam welded it, it looks fairly neat.
However I have a question.

I blew a little hole along one seam and so simply very carefully filled it
with mig wire, got a big pool of weld and gradually extended it over the
little hole, will this be strong enough? The pool of weld in the hole is
probably something like 5 mm.

I suspect the 3 mm plate will be strong enough for the MOT .

Yours Andrew

Yeah should be fine... I normally manage a few more holes than that on older
pannels / material.

OTT, in fact, the original chassis is about 2mm and that's before it rusts.

if you blew a hole, you didn't extend the plate far enough. The MOT type
probably won't fail it provided there are no actual holes.

When patching chassis, I tend to apply a smallish ball-pein hammer (about a
12-oz), ball-end-to, to the chassis around the visible hole, quite
vigourously. Often, the hole gets bigger, and any surrounding metal that
you can dent is too thin. especially with holes low on the chassis tube, go
along several inches around it, and hammer away 'til you're convinced you've
found all the weak spots, then patch all over the affected area.
