Nah chassis legs are part of the shell so lots of welding on my back. Got plans for a chassis roller so that will be the next major job

So subframe stays in place? unless of course the rot is round where the subframe attaches?

[davieboy0312]

in my case im unlucky. its right underneath subframe

[andyc]

Ah yes the subframe has been removed along with the trailing arms and diff. Nice little design on the Senator A and Monza is you can't remove the trailing arms without removing the whole subframe assy.

going to strip it down to a bare shell anyway for sandblasting

so im looking at 2mm for chassis leg and 1mm for everything else?

[Nick W]

2mm is far thicker than what's already there, and will be very hard work. Use 1mm(ish) for the chassis rails, and slightly thinner for anything that needs much shaping.
This will be easier to make, and to weld to the existing metal. Sheet metal monocoques get their strength from the shape of the metal, and so are made out of pretty thin stuff

[davieboy0312]

so one for chassis rail. would I be better removing the strengthening plate and renewing that to? pretty close to hole

I haven't seen an Omega B that rusty, but Omega As are mostly that rusty and the only real difference is the age.

just for reference, I'm just starting to weld a Vanden Plas Princess which has no floors at all, no chassis rails and no sills - indeed, the only reason the front stays attached to the back is that the doors are welded together.

Must admit that Omega does look the worst one ive seen , worse than the Triumph Herald i had that only had drivers floor pan holes .

[davieboy0312]

yea I didn't think it was this bad when I bought it. scrapped a W reg cause it had a massive hole at steering box about fist size cant get any worse though
