Talbot Sunbeam Rally car Brake fix

Malc had taken the car out a couple of months back and had reported that the brakes weren't working very well and that the handbrake wasn't working at all. As it will be in action at the Lombard Classic event at Revesby abbey this weekend we figured it was time to have a look and see what was what. It was easy to see that the master cylinder on the handbrake was seized, replacement or rebuild was the only option. As soon as I looked at the footbrake master cylinders I noticed some seepage so decided they would need replacing or rebuilding too. I looked up prices and found the price of 3 new cylinders was about a fiver more than rebuilding the original Girling items so we just bought new. Two of them were 625 - 5 /8ths of an inch and the one for the fronts was a .75 or 3/4 inch one.

DIY Paddock Starter Petrol Version

Those of you that followed my paddock starter exploits may well be wondering how well it went, well the answer to that one is - pretty badly. After having burnt out yet another starter motor I came to the conclusion that none of the top race teams were going to be coming to me to purchase my dodgy solution and that perhaps a change of approach would be the best course of action.

Honda RC163 Project - Painting the tank

I finally received the decals had been waiting for and applied them to the tank, I am very happy with them but wish sellers would keep their customers informed, I was sure they were not coming so ordered another set that I now don't need - all a bit annoying. Anyway, having learnt from my earlier experience I stayed with the Motip lacquer, I knew it didn't react with the paint I had used and that it went on nicely. It dried out in the sun, I am quite pleased with the results, it will look even better once it's flatted and polished, I will leave it at least a week to go fully hard before I do that.

Making the tapered muffler

OK, calling it a muffler is pushing the truth, amplifier would be a better description. There are no baffles in these exhaust, this is how they were back in 1962 or whatever, just straight through pipes that produce an ear splitting exhaust note, it really has to be heard to be believed. Anyway, I had watched a video of Allen Millyard being a genius making the similar exhausts for his RC166 replica, he made it look so easy. Except it really isn't easy, it was an absolute bastard of a job. It may have been better to have done it in less than 35 degree heat but the fact is bending a steel sheet of that size requires a surprising amount of force and you have to do it without denting or scraping the metal, it's an absolute pig. I have to confess to not being 100 per cent happy with it but without having proper rollers to form the metal I have done my best with it. If I ever find some better ones I will replace them.
