Another outrigger post

[S2Mick]

Hi all, new member here.
Recently acquired a 1989 S2 in need of a body lift refurb.
I've cracked on over the last couple of weekends, seat / seatbelt / tub bolts all coming out whole (surprisingly) with only one requiring the attention of the noisy hacksaw and about a gallon of duckoil.
The tub's now off and I should have the engine out over the next couple of days.
Does anyone know where I can get my hands on the chassis dimensions or a schematic diagram with measurements as I fear the thing that returns from the shot blasters may hold little or no clue to how it needs to look when repaired ?
TIA

Have a read of this - it answers most of your questions

How about pushing some slightly under size tubes inside the shredded ones? They will survive the blasting and give you some reference points to work from.

[S2Mick]

That's a great idea. I'm lucky to have access to a good welder who hasn't done an S2 chassis before but is a first class tube and profile welder. If the chassis was any worse (and I'm encouraged by what I'm finding) it would have been straight to a specialist but so far it may just be both front corners. Guessing once it's blasted it may be a slightly different picture.
Thanks for reply, much obliged

I replaced the outriggers on my S1. The steel is quite cheap. Once cut and tacked in place I paid a welder to complete. There are a couple of good threads on the Chimp page by Classic Chimp and Chimpongas regarding the recording of the chassis. Look at marine paint. 8 years ago I painted the chassis with smoothritwo. Several layers of different colours. Last year I inspected and found no rust. Check out my post on here.... Cosy sold and Jag bought......

Cheers Mick, just back from the shed and finished by running and clamping a piece of angle across the underside of the chassis to get a reference point re height of the outrigger.
I've now mapped the reference point you point out in red for the rebuild thanks.
Nice RS 200 by the way

I sold the RS200 10 years ago for less than the cost of the parts now the prices have sky rocketed - the monies allowed me to purchase the crap S1 I rebuilt with a Cossy engine, I have just fitted a Jag engine.

I’m doing my outriggers at the moment. it’s an 1988 S1. So will keep a record of the dims if you need them, but try and get your dims, all TVR are different.

Please note tube in your photo, the one from the chassis to the outside Is not level and different heights from the floor, it’s about 15mm (I think) lower where it exits the chassis to the outer height. You will notice that this tube runs right across the car, it’s actually 1 tube with a kink in the middle (so one long very slightly V shaped tube)

[88S1]

Got my tube off eBay. 1.5” x 1.5mm ERW tube. It’s £25 for 3M length but you can choose what length you want.

Thanks Lee, tidy job that.
Yeah, I'll post later but have run a piece of angle across the chassis using the middle rails as fixed points and measured how high above the angle the outrigger leg fixes to the rail and how high above the angle it is at the outside (if that makes sense).
Hoping to post a pic with all the outrigger dimensions on here once my IT expert (16 year old son) has downloaded the pics and drawn the dimensions on them.
Great job with the refurb by the way, loving your posts on here

Sounds like you’ve got everything covered, look forward to seeing the end results.

Check thoroughly for rust

You can always modify to tuck the exhaust up to give better ground clearance
Every mm matters when 'slammed' as youngsters say

don't forget to apply a good protective coating

@Magpies. It’s hard to see what you’ve modified to raise the exhaust, but agree the “slammed” look does look good. I love your wheels and mods you’ve done, car doesn’t look like it’s 30+ years old.

I notice you have additional plates on your outriggers, what are these for?

[Bercilac]

Looks like a plate for a roll cage maybe? Love that look, very purposeful. I've left mine at the regulation height and it still grounds out driving down the 700 metre dirt track to go sailing :-(

18mm plywood, 19x38 battens. Make up jigs on the car. Then send off for blasting. Personally, I would pay extra for CDS and go 'up a thickness' for the new sections. While you're at a chassis refurb, add some chassis sections to fix the seats to. Cut some tube of the next size up in half and add them over the front rail of outriggers for jacking protection.

Good call. Have you seen how flimsy the seat mountings are? It's possible to add bolt-on braces without taking the body off, and it might be easier to get them to fit the floor profile if you do that rather than weld them with the body off.

yes added plates for cage to bolt to

rear chassis in front of the fuel tank relocated a couple of inches higher.


56 extra plates welded in for strengthening - edited as uploaded wrong photo

I do run my S a little lower than others - as the exhaust has been raised, the car does not bottom out as much as the standard ones.
