I initially started doing the chassis repairs in situ, but when I started cleaning the underside decided I couldnt do a proper job with the chassis restricting access to the underside of the car

The chassis wasn't in too bad a condition, but water had got inside, I think through the two front horns ( Jacking point members. The chassis is a fabricated construction using 2mm plate throughout ( SWG 14), the plate on bottom of the flanged "U section " is spot welded and on the jacking tubular section it is just tack welded ( see Pics) and I think this is where the water got in .

It was always my intention to replace the plate on the bottom of the two main rails as this had been indented over the use by indiscriminate use of trolley & bottle jacks . I found corrosion pin holes where the flange was formed on bot sides of the main rails, as the rails passed up to go over the rear arches, to where the flange disappears . Also on the internal flange forming on the N/S rail about 2' back from the front X Member for about 2'

I used plug welds instead of the original Spot welds, these were at 1" centres , 5/16" in from the edge of the plate utilising 7.5 mm holes

This photo shows the welds before & after grinding off . The chassis has about 1 days work prior to being shipped off for blasting & painting. I forgot to mention . Where the Jack horn tack welds were , I replaced this with full seam welds to prevent further water ingress

Alan,

Are you doing the work by yourself? Any idea of the cost to date?

Well done,
