The Large oil tank down tube Manx with leading link forks is definetly a Ken Sprayson Reynolds product.the picture of the Arter raceris the short circuit bike as Peter Williams used pannier tanks for the TT,Dave Hughes was working on the Racer in his garage and took off the beautifull tank that you can see and placed it on a blanket on the trunk of his car,he went round the back of the house for something,when he walked back into the garage there was no car and to his horror the tank lay dented on the road he said he was nearly in tears.his wife was lucky not to be around.
The Hailwood Honda has Colin Lyster Disc brake conversion,
peter james owen said:e Norton 650 that Phill Read and Brian Setchell rode for Syd Lawton were a mess,the bikes were built specially for the production races,and were very late in arriving from the Bracebridge street factory,When Phill was running them in on an old airfield,he found the handling to be very poor,I mean very poor.Syd said "dont be silly these are a factory jobs"with that he jumped on the bike in just a jacket and trousers no helmet and shoes he then gunned it down the airfields taxi way,the next thing he had been spat off at high speed,when on being inspected the frames were out of alighnment with the wheels laced up out of true,so much for being a factory bike it looked as though the bike had been built from rejected parts.And Syd was very lucky to get away with cuts and abrassions.
They ran a factory 88ss in one 500 miler in about 1962,it was very quick,as fast as many of the big Enfield 700s',factory Amc,triumphs and bsa's. they told Syd not to let anybody near this engine,it later came out that the engine was the development Dommiracer,the one that came 3rd with Tom phillis on board.
acotrel said:How do you stress relieve or anneal a frame which has been bronze welded without metallurgically altering the joints ? I can see real value in doing it to a steel welded frame while it is still in the jig - otherwise ?
lcrken said:I don't see how you could anneal a steel frame that is bronze welded. The annealing temperature for low carbon steels is around 1650 degrees F, and most bronze welding rods melt somewhere around 800 degrees F.
If you're talking about post weld stress relief, the usual soak temperature for steel sturctures is 1100 - 1250 degrees F, still way too high for bronze welded joints.
Rohan said:Tin-bronze melts at approx 1750 F, depending on the alloy % composition.
Assuming tin-bronze is even involved in featherbeds... ??
hobot said:The few old tube joints I've see done heated until the solder or bronze stick melted on joint contact to wick up inside the joint.
