Replacement spring hangers I made compared to corroded originals (I made the new ones 6mm wider then inserted 2x3mm washers) this was to allow adjustment of the leaf springs from side to side by shimming should I have got the measurements wrong. As it was I hadn't.

I had the chassis shot blasted to basically give me a clean base to work from and also identify any corrosion.
On it's return numerous areas of corrosion had come to light. Now rightly or wrongly I decided to basically plate over the affected areas with 3mm plate. Each surface was first treated to weld through primer, I then seam welded in plate on both sides of the chassis so I ended up with mirror image repairs.
I approached the repair in this manner for two reasons;
1) By doing the repairs exactly the same to both sides of the chassis means even weight distribution.
2) Due to the repairs being seam welded and leaving the original metal in place the chassis should be more rigid, and therefore be more taut on the road.
The downside is I've added additional weight to the car and the possibility of corrosion occurring between the metal let in, and the original chassis. With regards to the additional weight I don't think this will affect the day to day driving of the car to such an extent it will take away any pleasure. As to the corrosion the weld through primer should eliminate any problems along with injecting the chassis with waxoyl.
I made up new spring hangers and welded them into place.
As the Daimler will be driven by both myself and my wife, Anne, I decided to incorporate other modifications to the chassis. These include conversion to rack and pinion steering and telescopic rear dampers.
I purchased a damper kit which includes a frame which is bolted down onto the chassis near the spring bump stops. The instructions suggest drilling and tapping the chassis to mount the frame, which in turn supports the top of the shock absorbers. As the chassis is only about 2mm in thickness I thought it would be a bad idea to tap a thread into such a small surface area. I decided on a belt and braces approach by first drilling the chassis, then welding in nuts to accept the frame securing bolts. I then plated over the captive nuts to prevent them from being pulled through.   
The next stage was to fit new chassis sills ( my car is a 'B' spec), these were purchased from David Manners. As the sills were only constructed from spot welds I again seam welded these items and capped of the front of them. This is to prevent debris thrown up from the front wheels entering the sill sections.
The chassis was then treated with paint obtained from a ship yard. This consists of a primer (silver in colour), an undercoat (matt black) and a top coat (gloss black). The first two were hand brushed on with the top coat being sprayed. My logic for using this paint was that it is designed for use in salt water, and so should be okay for road use. The finished chassis will be eventually sprayed in a waxoyl type product which should take the sting out of road chips.
I have since managed to trace a sizable amount of history relating to the car. If anyone wants advice on how to do this I'll only be too happy to advise them. I'd also appreciate any feedback on how you think I'm tackling the restoration whether it be positive or negative.
