Hi everyone.
My first post here. Just wandering if anyone knows where I can find Griffith chassis diagram ( diamentions angles etc). Is it included in Steve Heath book? Just ordered one but waiting for delivery.
All the best
It doesn't or at least mine doesn't but if you manage to get that information I would love a copy. Welcome onboard. PeteMy first post here.

Not an engineering drawing but a lovely piece of work....

Doc Toad very nice drawings!
Well I come to an age where one hits midlife crisis( early 40's).To solve this I had several options to choose from. After a few months of weighing them all up I shortlisted 2 obvious ones.
1. An affair ( which would be just too easy in my line of work )
2. A nice sports car.
After few more monts I concluded that the second will be much cheaper and safer, as my wife swore to quote ( scratch that b......'s eyes out, and cut my b...s off with the blunt knife).
So there it is option 2 obviously.
I had a 944 turbo and an m3 before but I always had an eye for a TVR. I found one in Belgium but it looks like it needs some work to body and frame. I have an engineering background , worked as welder and machinist for nearly a year ( I can produce some quality work) before I decided what to do with my life. During my college years I did a lot of summer work in ship yard working and repairing composites. It becomes quite easy once you've messed up a few pieces.
I can pretty much fix a Griff from bottom up in my grarage. Now the only thing I'm missing is a frame diagram.
I am thinking titanium but for something that big it would prove quite difficult because it requires a controlled environment ie argon envelope, before you attempt welding. I will certainly do the suspension arms in titanium.
Thanks for your replies guys, and let me know if you find something.

+1 on your approach to mid life crisis - very sensible!
IMHO though - might be minus several million on building your own chassis...?
I suspect even something as exotic as titanium ain't gonna make a lot of difference on a chassis design thats quarter of a century old so why bother?
Stick to mild steel and blow the cash you save on go faster/louder bits and a lairy paint job/interior - thats the mid life crisis formula

Glide, I have a proposition. If you know somebody who knows how to do 3D Laser Surveying or whatever it is called, I have a bare chassis, sandblasted and straight (as far as I know) they can do the survey on. Probably won't go anywhere but just a thought. If you do know anyone, I am happy to share reasonable costs. PeteNow the only thing I'm missing is a frame diagram.

I'm sorry for delayed reply but I had a few demanding days at work in the aftermath of recent events.
I've contacted one of those companies , now waiting for the reply. I should know , I guess by tomorrow if they can map the chassis and approx cost. My only concern is that mapping the frame will inevitably include any misalignment errors however small. There's a possibility of magnifying it during reproduction. A set of original specs drawings would be A much better solution. I've also looked at sportmotive option. Their standard one " with in house improvements " is 4k , which I think is quite a good price. I guess evo would be at least twice that.
Any thoughts.

Why bother trying to fabricate a new chassis when the old one can be easily repaired, or if too fat gone, a new one sourced from one of the independent TVR specialists for 3k gbp or so?
Titanium will be quite difficult to work with and expensive and the weight saved not worth much since the chassis isnt that heavy in mild steel. Plus making a jig from scratch will take time and money.
Stainless will crack, eventually. Refurbing the original chassis is far easier, cheaper and more likly to be successful.
If you really want to save weight, stiffen the car and spend huge amounts of money, someone on here built a carbon fiber bodied griff. You will neec 25 to 30k plus though......

Glide, not a problem. When I first did my rebuild, I did quite a lot of searching for drawings, dimensions etc. because when I started my stripdown/rebuild I just assumed that I would need to weld on new rails. I couldn't find anything. As it happened my chassis rails are fine and as far as I can check the chassis is straight and undamaged but nevertheless for 'the greater good' of all Griff/Chimp owners a set of drawings and specs would be very useful.I'm sorry for delayed reply but I had a few demanding days at work in the aftermath of recent events.

I am in two minds here, perhaps we should be supporting the specialist suppliers like Sportmotive as without us they may go out of business but on the other hand I do like to do as much as possible myself and that would include chassis repairs.
The chassis is available, the rebuild is 'on hold' right now as I have the 'garden project' to crack on with so the ball is very much in your court. Perhaps Ste's idea of making a jig could be a good one. As I said before, I am happy to share costs or perhaps we should seek some sort of contribution from TVRCC out of our subs as this is definitely something they should be sponsoring. Pete
OK Guys, better late than never.
I was determined to get my chassis scanned before I got it galvanized and starting rebuilding the car. My vision was to have a 3D CAD drawing of the chassis, fully dimensioned so anybody could use that to check their chassis, rebuild, make a jig etc and generally add more knowledge to the Grief/Chimp fraternity.
On spec I rang up a local scanning company Sun Hill Surveying in Aldermaston and spoke to the owner, Pete Coffield. This was a million miles from their normal operations, they do scans for big road works/repairs and that sort of thing but Pete thought this would be a 'bit of fun' and scanned the chassis for me as a freebee.
So here it is:
Still looks a bit messy but I am cleaning it up to get rid of the 'noise', including the stand it was sitting on when it was scanned.
So two related questions for you guys out there. Does anyone have the knowledge/software to produce an accurate 3D drawing from the scan? I'm guessing you need something like AutoCAD and a bit of patience together with some accurate dimensions for tubing diameter, which I could give you using a pair of callipers.
Pete has said he would do another scan to see if we could cut out some of the 'noise'. Do any of you have the experience to guide us on how best to go about this to produce an accurate 3D CAD drawing?

Hi Pete, a question - what file format did they give you? It is quite possible that they could provide a suitable format that can be read by AutoCAD SOLIDWorks, which is the 3D rendering package. One of my clients uses this package for there bespoke vehicle design, so I could inquire? Just a thought!

Hi Pete, I thought you would pop up sooner or later, this is right up your street. The format is Recap from Autodesk, which is a freebie and enables you to take out the 'noise' from the scan. As AutoCAD is an Autodesk product it is probably in the right format but I am sure Pete will give me the file in any format I want as well as rescanning the chassis if need be.
Believe you me I have no other use for this than general curiosity and increasing the knowledge and data available to us Grief/Chimp owners but I didn't realise the process of turning a scan file to 3D CAD was so undeveloped.
Cheers Pete
