I popped back in the garage this afternoon for some gentle dashboard work. Or gauges, if you prefer. But today of course was one of those days where if anything was going to go wrong, it would. Allow me to elaborate.

The rev counter I now have has no needle on it. I figured I could easily fix it by removing the speedo needle from the clocks I already have. SO out came my gentle plastic trim removal tools and I started gently persuading it out. It was very tight and very stubborn. Eventually, it gave up and let go. Or so I thought. Nope, it had snapped the little prong that the needle sits on. Great.

I managed to get the prong out of the needle with some gentle work with some needle nose pliers, then set about putting it on to the rev counter. And I ran into yet another issue. At some stage Austin / Austin Rover / The Rover Group or whatever they were called that week had changed their design oh so slightly. The outside diameter of the old-style needle? 3mm. The diameter of the hole it had to go into in the newer-style clocks? Yup, 2mm. I thought I would be clever and gently file it down using a needle file (geddit?!). Did this work? Nope. All it did was collapsed the plastic so now I can't use it at all. It was at this point that I shut the garage door and walked away.

Anyone got a 90s Cooper-style rev counter going cheap?

So I thought I would be clever, and use the needle from my other speedo. Instead I broke bits and got frustrated.

any chance of doing something creative with a cocktail stick, araldite (or epoxy putty) and your old needle .
I am old enough to remember tales of rotor arms being replaced with a cork and a pin

I would have to be pretty accurate - my hands are more accustomed to nuts and bolts than tiny pins I can barely see. I have put the feelers out for another rev counter.

I have decided that I do not like gauges. Or, more specifically, old gauges in various states of "Nope". I have decided to revert to my initial plan of the two-gauge pod in the dashboard, as I have had enough of man-sausaging about with trying to sort a working 3-pod rev counter. I do have a 52mm rev counter, which has never been used. I just thought that perhaps a 3-podder would have been easier. Sadly, today they are not as easy to come by, and when they do turn up they're often silly money. I can practically buy a digital speedo for some of the prices asked. I shall leave those overpriced Cooper items to the originality fans. Also, with the youngest being 20 years old, condition is not always going to be the best, especially with the ones I don't have to give my left plum for.

I thought that it would be pretty easy to simply transfer the innards of a GT rev counter into the pod of a 90s Cooper rev counter. Sound easy? it isn't. The plastic pods they mount in are different. The actual body of the rev counter is different (and by some margin). And, to all insult to injury, the printed circuit boards are massively different. So I will continue with a 2-pod set of clocks and use my smaller rev counter.

I turned my attention to the two other small gauges I have. The voltmeter I have (which looked great cosmetically) was not so great inside when I went to clean it. In fact it may have been stored in a small pool of water for some time. So that's in the bin. I am also not keen on the oil pressure gauge I have acquired. So I am once again on the lookout for some different items, and I have got no further with my dashboard. Nuts.

1275GT casing is similar but different enough to 90s Cooper casing to make it unworkable.

Cooper Rev counter innards extremely different to 1275GT innards. PCBs are different too.

Even the two smaller gauges were no good. Don't like the look of the Oil Pressure Gauge and the Voltmeter, although cosmetically nice, was scrap inside.

Well as I was so annoyed with the dashboard work, and I'd got an expenses claim approved at work (a rare thing in my job...), I did a bad thing and ordered a few things from Mini Spares, because, well, you know, THE EXCITEMENT OF GETTING A BIG BOX! One thing that's bugged me was the lack of an exhaust. The original Midas exhaust from the factory from what I understand is a bit of a pea shooter and the likelihood of finding one is somewhat small. And having waited for a secondhand exhaust to experiment on for FAR too log, I figured it was time to do something. So I bought a twin box RC40. Now, I know this is not likely to fit properly, but I figure that with a little bit of adjustment (cutting and welding here and there) and maybe a couple of extra bits of pipe, I should be able to sort something that is perfectly usable and isn't a complete Frankenstein of a system.

Other things in the box were an oil pressure pipe and adaptor, an exhaust fitting kit and a pair of 3mm spacers for the rear wheels - if I go down the route of 165 tyres I want to be sure of clearance. Finally, Tink gave me a special prezzie - an aircraft-style switch, which I will probably use for the fuel pump. Epic.

Voltmeter bolt was so rusted on to the stud, that instead of it coming free, it ripped the inside out. I thought it was undoing too easily...

...and a pair of 3mm spacers for additional clearance without the need for new studs.

Plus Tink gave me this awesome switch. I think I should put a transfer on it. But what???
