Following six months of not being able to work on Lancias due to mental incapacity and other commitments it is time to get one of my Lancias back on the road. The Y10 is the most useful everyday car so it is up first. Y10s are prone to damp under the floor mat in the boot and consequent condensation internal misting up. Over the years theories have been bandied about ranging from leaking rear washer unions to condensation caused by the exhaust heating the floor. I'm pretty sure in virtually every case it will be the dreaded rot even if you can't see anything amiss. This is what is left of the rear corners of my apparently tidy Y10. A rebuild is underway involving extensive use of CAD technology (Cardboard Aided Design).

Whatever the cause the solution is the same...

Keep the photos coming - and hope you can hear me cheering you on.

Fingers crossed for long warm evenings and clear dry weekends when you need them...

Chopping out has begun. It's a devilishly complicated conjunction of panels.

Over the weekend cardboard aided design continued, some patches were cut and today I started to dial in my welding. The seam at the bottom is where I ended up which I think will do. The challenge is to repeat it consistently.

Some funky curves.  What are you using to cut?

I'm using an electric jig-saw with a metal cutting blade for those bits David. I decided the lower part of the inner reinforcing moulding needed to come out to allow access to attach new metal behind. I now have patch 1 and patch 2 in place. Next that reinforcing moulding has to go back in.

Complicated...I expect very gratifying.

Looking good.  The sort of job that can only be done for the love of it.

Here is a picture of the jig-saw and another of all the tools that are in service for this job. It takes rather a lot of clobber!

Today's work has seen the boot inner panel and the inner wing patched. It would be much more satisfying if I could get the knack of running consistent, even welds but hopefully practice makes perfect.

The thing with ugly welds is that you can always grind them back to something pretty...and if its still ugly add a bit more...(etc, etc, etc...)

Rain has stopped play this morning but I need to shop for more consumables.

I am trying to preserve the paint finish outside what will be covered by the rear lights. It occurs to me that there is so much steel in the back corner with all the different layers of panels coming together that the outer panel isn't really structural. That has made me think of gluing a cosmetic repair patch in place. Has anyone any thoughts on this?

I'd trust your instinct.  Go for it...

(if outside the MOT "must be seam welded" zone)

Saw Landrover Velars being built over the Easter holidays and its all that holds them together.  The surprise was that they've VERY similar to a Jaguar F-Pace, which is built in Solihull on the same line.

There's a link to the regs in there, and discussion of seams and spots etc and what items you need to be 30cm away from.  Eg seat belt mounts.

Thanks David, that makes things much clearer. Patches must be seam welded to restore continuous metal in the panel and spot welds (or substitute plug welds) used at original panel joints to preserve the same panel deformation characteristics and ensure proper performance of crumple zones.

I did do some work today by doing most of the work on a new bumper mounting bracket.
