Cleaning the crank case

Of course it isn't all exciting. Sometimes it's gently getting off years of accumulated baked-on Castrol R and filth without damaging anything!

Perot shafts finished

A finished perot shaft on a very dusty chassis. Also visible are a stainless steel hubnut, the dynamo housing casting and an unmachined block in the bottom right. It's great to see parts bought at different times from different people starting to come together.

New dynamo housing

This is the first new dynamo housing to be fitted since the 1920s. Nobody has ever managed to cast one since then. It took eighteen months to get the patterns and the casting process right, but they finally figured out how to do it. The first picture shows it clamped to the sump and crankcase after machining it to fit.

 

then drilling the first datum hole through from the sump

then after a certain amount of paper pattern making, then aluminium pattern making, then marking and drilling and measuring and checking and double checking and programming coordinates and centering....

Not mine, but the first new crank installed.

This is the first of the new cranks installed in a crankcase, not mine sadly, but my time will come!

Silencer repair

Annabel is going to need a new silencer, but in the meantime... A "proper" vintage repair, done according to long-standing tradition, in Halfords car park, popping in and out of the shop to get extra bits as required!

Rotax fusebox

A Rotax fusebox, I've never seen one before, not even on a car. It could be from the 20s but may be later. If anyone has another I have a good home waiting for it!!
