A new Big 7
#12
It took an interminably long time to find the necessary spares for this engine build. A set of +20 pistons came from Scotland after a chance meeting at the centenary, Tony Betts was able to find some shells andĀ valves, thanks Tony. The Big 7 register was able to supply some new parts but Robin has been in poor health for that last year or so the spares scheme has been operating very slowly.

However, just before Christmas, the block and crankshaft were dispatched to the machine shop and I had word today that they should be finished next week. In the meantime, I have been cleaning:

   

I also had to machine the water side branch, which the Register were able to supply but in unmachined format.

I have also made most of the gaskets, the Register has a few but not enough to rebuild an engine:

   

Lets hope the building can begin next week.

In the meantime folks, thank your lucky stars that we have all the spares that we need to keep the "Baby" Sevens on the road!
