This has been quite an eye opener. I don't have a gauge to tell me exactly what I need anyway and I believe that some threads are easily confused with others. At the moment I only need one tap to get a car back on the road, but will have to start looking at a more comprehensive collection.
Hi Mick, I do know of that car and I believe the owner attended the club event last weekend in a significantly more modern Volvo. From what I'm told the car would need a full restoration. There is an article in a recent Practical Classics about the restoration of "The Saint" car and it looked like a frightening task. Engine and drivetrain is all fairly simple, but the body, interior and trim is seriously complex and expensive. A restoration specialist company spent 3 months just putting the body back together :oQuote:

If you have any recent pics, the club would love to see them.
that said, they are pretty good for the price you pay for them and if you use a little trefolex or other cutting fluid they behave perfectly well for the average joe with an iq above 5 that doesn't attack stuff like a bull at a gate...Quote:

Thread charts are attached.
Sorry, the system won't let me attach them. Says they already are elsewhere. Search for thread charts.
I haven't seen the car except for the tarp for over ten years. I think you would be right, there would be a lot of work. A real pity.:( I think he enjoys driving the modern version though, and he does like the fact that the rear window is a throwback to the P1800 ES.Quote:

Might have been Citroen's own creation. Whilst taps are available, the size is not mentioned in any of the recognised guides such as Machinery's Handbook and Sidder's Guide to World Screw Threads.Quote:

Probably a few more I have forgotten or not yet encountered. My personal preference is NC, NF, NEF.
How many of those standards overlap? I can't see my self having to use a horological thread on the same thing I would use a Marine engineers one on. Trust the French to come up with two that probably do overlap.Quote:

I even managed to get that satisfying sensation of being covered in gear oil and filth by accidentally rolling in a puddle of the stuff.
Thanks for all the help!
I think the M5 x 0.75 is a very early metric "standard" pitch... Everyone started using M5 x 0.8 so they moved to that ............. Part way through the production of a vehicle :wallbash: Who does that ?? (it could be worse, bloody landrover appears to have mixed metric and imperial on the same vehicles ... bloody crazyness I tell you!) Yes I'm always using metric thread gauges to work out what the hell is what. On the one car I found these sizes. M5 x 0.75, M5 x 0.8, M5 x 0.9 and M5 x 1.0 ....Quote:

Is this the best project car you have ever seen? - Page 9
M10 x 1.0 anyone ?? sigh ... Lucky the majority of threads that I cleaned up were M5 x 0.75 and M7 x 1.0 (which I had taps & dies for ).
seeya,

If you have a late Series 3 Landrover, you will find that it has metric threads on the engine and a few other bits, mostly unified (UNF, UNC) threads on the rest of the vehicle, and a few BSF bolts where parts have remained unchanged since Series 1/2. Probably a few BA as well, although I can't think of any!
