Not true Mr Towed - rotors manufactured to original spec last extremely well, I have never had one fail on me in thousands of miles motoring with these engines.
Unfortunately there are many cheap reproduction parts that do not hold up so well - so my advice is, spend just a couple of quid more and be sure to get an original spec part (but you can always carry a spare for peace of mind of course!)

I've had three of these fail now - the one the donor came with broke in two while I was still trying to test start the engine for the first time, a cheap one that came with the electronic ignition module also broke in two after a couple of test runs, and now this one's sheared off its drive peg (that keys into the slot in the distributor shaft), so I'm beginning to think my distributor might not spin true, putting undue strain on the rotor arm. Will have to check the shaft for run-out methinks...
In my distant memory there were issues with pattern dizzy caps having their pins too close to the rotor arms as well as wear in the shaft/ advance retard.

Yep, that could be the problem. It looks like the business end of the rotor arm might be fouling the contacts inside the cap - they're supposed to skim past without actually touching - so I think I'll pull the distributor with the cap and a new rotor arm fitted (when they arrive) and turn it by hand to see if I can feel any restriction.
Surely if that fouling was happening, you would hear some sort of "ticking" sound?
It certainly seems to be some sort of physical problem causing so many failures.
Some years ago, I had a problem with my GT6, at speed it was fine, but at tick-over it miss-fired terribly.
Turned out the bearings in the dizzy were very worn and it flopped about at slow revs, but centralised at high revs.
However, it never damaged the rotor arm at all.
Cannot imagine what could cause your kind of damage.
Well, having visited Stoneleigh, and been totally blitzed by some of the exotic creations I was bowled over by, I realised I needed a "bling-ring" for my new Monza petrol cap.
So I quickly knocked one out, made out of?
Stainless steel of course (as it's so cheap and plentyfull), bit fiddly cutting out. filing, sanding and polishing, but it's done now.
Then I realised I would have to make one for the gear lever, and one for the handbrake. Poosticks!
I must try not to get carried away and overdo the bling!
When I put the louvres into the bonnet, it somehow slightly warped the shape of the curve at the rear near the windscreen end.
I was not happy with that, so I slit it, re-curved it, and got it wrong.
I then did it again, knowing it had to to come up half inch on the left side, quarter inch on the right, and so on. I clamped it into a jig I had made for that purpose.
I made it worse!
It began to dawn on me that the jig would have to be much more refined and perfect, if I was not going to have to do it a fourth time.
So that is my job today, (which for obvious reasons I have been avoiding like the bloody plague.
I have just bought a new toy, a sheet metal cutter.
I have owned hand nibblers, air nibblers, air shears and all sorts of like stuff, and still have most of them.
They all have one thing in common, they work, but only on really thin metal.
Give them some thick beefy steel and they are not really up to the job.
My new toy was chosen with care, it was not cheap, and is top of the range.
It will cut up to 4mm thickness of mild steel, 4mm of alluminium, and 2.7mm of stainless steel.
And it does all this in real style!
It absolutely batters it's way though it all,really quickly, and more importantly, does the cutting with no distortion.
It is 240v electric, and has a 625watt motor.
I just wish I had got one of these earlier. I can now plan more exotic stuff for the car, like stainless steel headlight surrounds, which ought to be a doddle to cut out with such a machine.
I shall be inventing jobs as an excuse to use it!!
I don't have steel that thick to try it on, but that is what the sellers claim.
The way it cuts the steel I have, I wouldn't doubt it.
It's basically a large nibbler, a punch if you like, when cutting, it sounds like a machine gun and a shower of the punched out fragments fly toward the floor, really awesome!
