Chassis Refurb

[Jon12345]

So it begins

[AdriaanB]

Very interested in your progress - pictures of the process would be much appreciated I'm factoring in a chassis refurb of my 'still to be bought' TVR, so hope to learn as much as possible here!

Good luck, it's a big job!

With any luck my body should land back on it's refurbed chassis tomorrow. It's only been (exactly) 11 months since it came off!

[Jon12345]

Yeah it's going to be an eye opener, I have been collecting parts for the last 6 months. If there is anyone up north who has any spare time on their hands to help a fellow yorkshire man out, the doors open with the kettle on

[Jon12345]

Boatbuoy how did you treat the chassis, I have been reading many topics on por15 vs 121epoxy vs powdercoating, can't make my mind up which is the most durable and lasting finish

I would love to help but I am a mechanical numpty. However, when mine comes back, you're welcome to come out for the odd motivational run to keep you motivated!

Hello and welcome

Where in South Yorkshire are you?
I'm in Doncaster, there's loads of spanner holding Cerb owners in Yorkshire!

POR15 is not designed as a clean metal finish, the name is from Paint On Rust. Regardless whether you go for an epoxy or powder coat finish, I strongly recommend you investigate zinc metal plasma spraying to protect the metal under it. It has all the advantages of hot dip galvanising without as much added weight or the risk of heat distorting the chassis. I had mine treated with this before powder coating along with all the suspension arms and brackets. I also had as test plate plasma sprayed (without powder coat) which has been hung outside for nearly 3 years now and still has no sign of rust what so ever.

Thanks, I have read about this before, where did you have you done and did it cost the earth?

I had it done by the powdercoaters that did my chassis ( www.nspcoatings.co.uk in Gravesend Kent) and as far as I recall it added about £150 to the cost of the powdercoating.

Got the stripping underway today, found some suprises already. The air box connections have been repaired previously and have been crushed due to over tighting. Also there is a drilled hole on one of the air boxes any ideas what's it for?

For the atmospheric air pressure sensor (a rubber pipe).

[Jonbouy]

Thanks gazaab, where does the other end of the pipe connect? The was clearly nothing connected to the air box when I removed it

Hi Jon,

Sorry it's taken so long to respond. Saturday was a busy day in the workshop, followed by too many beers at a Burns Night party. Today has been a day of recovery and I've only just looked on here! As Tanguero said, POR15 isn't really the best way to treat a 'body off' chassis refurb. Mine too was given the zinc primer and powder coat treatment. I stripped the chassis of all its components and sent it and all the associated wishbones and brackets to RT Racing in Sheffield (as seen in the Wheeler Dealers show), they shot blasted the metalwork, made the required outrigger repairs and sent it to the powder coasters, who then bead blasted, primed and powdercoated the lot. I think the total bill was two and a bit k, but RT won't quote until they've assessed the blasted chassis. I'm very impressed with the results, it's just a shame the hard work is now largely hidden from view. My advice would be, that if you've gone to the effort of taking the body off you really shouldn't scrimp on the work or materials. Do it right, do it once! Anyway, good luck and stick with it!

I'm pleased to report that my car's body is now back in its rightful place, and hopefully on target to re-apper at this year's Burleigh House meet.

Some pics from Saturday to fire you up:







Regards,
Olly

Looks great ! Just looked at RT's jig on their site and assume its not a Cerb one? Do they offer brand new chassis for Cerbs?

Edited by OutlawFlat4 on Monday 26th January 11:30

As far as I know the jig at RT is from the Malaysian Chimera factory. New Cerb chassis are available from the Bulgarians I believe.

Although not brand new, its likely RT will have a fully refurbished Cerb chassis in stock. Give Richard a buzz.
