Just goes to show that all the rusted bits are the very bits you cant get at with the body on! First job for me when I start restoring mine.

Nice chassis, still deciding on the chassis prep and final coat? Galvanising or hot zinc spray. Would preferably like something that would also coat the inside of the chassis asset as the outside.

Chassis update

Chassis repaired, both outriggers replaced and some light welding in other areas. Managed to source the exact some outer-diameter tubing as the original but with a 3mm wall. We turned the tubing down on a lathe and slotted it into the existing frame so there is a seamless finish. Most of the metal plate was also replaced.




On its way for the repair work, welded etc.



We fixed it to 5mm steel plate and used this as a jig.

We sand blasted the small bits which looked like there could holes or excessive rust and repaired were appropriate.








after the repair work, we shipped the chassis to the blasters.

decided the best combination route was blasting, zinc plasma spray, epoxy under coat and 2k gloss white top coat. All the processes were of a high standard, the company I used carries out a lot of work for marine type applications.

The drop off at the blasters.

epoxy primed.




2k top coat finish.

Any updates?

[Jonbouy]

Well firstly there have been a lack of updates due to new baby and recent developments on my house have set me back a bit. Any how I have made some reasonable progress which I will post over the next week or so, starting now

Once I received the chassis back I felt that the finish wasn't upto standard so I decided to repaint the chassis, so I re-primed the chassis with two coats of primer and a further three top coats, in total seven coats in total plus zinc thermal spray. I also had all the wishbones, hubs, anti-roll bars etc shot blasted and thermal zinc plated. These were also painted at the same time as the chassis.

After many emails back and forth to PPG paint system Laboratory I final decided on using Sigmadur 550 and Sigmacover 456hs for both its gloss finish, hardness and durability.

All the parts painted, and brought back home ready for the rebuild, all new standards bushes etc.

more updates tomorrow

Time to order some parts, most of the parts came from TVR parts.

I also intend to replace every single nut, bolt and washer removed for new.

While I would have no qualms fitting Delphi track rod ends (which I think I can see there) I won't be using Delphi Ball Joints again - Lemforder only for me from now on.

One word of warning is that where you have painted mating surfaces such as the uprights the paint may need to be removed or it will gradually squeeze out and allow the joints to go slack. At the very least you may need to go back after a month or so and re tighten everything.
