Hello,
I have made a bit more progress.
The inlet and exhaust manifolds are now done.
They took me a bit longer than I anticipated.
I need to think what the next steps are.
There is still plenty to go at, but every part is a step closer.

Hello,
Again it has been a while since I posted any progress.
Progress has been steady.
It is probably about 90% complete now.
All the internal parts are made apart from the piston rings.
I have been following the post on the Westbury Seal, I am struck by how similar that engine is to this engine.
Lots of the parts are made almost to the same design.

Hello Tony,

I have been following your Austin seven story since you started it all those years ago. In fact it was one of the inspirations for me to build the Westbury Seal. You are so fortunate to have a full size one to copy.

Your workmanship does you credit, it's a good looking engine, and well made. As gbritnell and Nick say ' would like to have seen more build information'. It's not too late to post more photos.

The side valve Austin Seven was immensely popular (and affordable) in England during the 20's and 30's. It inspired enthusiasts to build homemade 'specials', there was also the very popular '750 formula', which was the breeding ground for a number of big names in motor racing in the years to follow. So it comes as no real surprise the Edgar Westbury borrowed much of the 'Seal's' design details from the Austin Seven. At the time, it was how auto engines were designed. Pity he did not incorporate the later centre crankshaft bearing

Keep us posted as you proceed to the finish line.  :ThumbsUp: :ThumbsUp: :ThumbsUp:

Mike

How are you lubricating the crank? Will it be splash or jets?

Thanks for the comments.
I will dig out a few more pictures of the build.
Mike, this engine has a two bearing crank.
It is simpler and the engine in my car is the two bearing type.
Apparently the three bearing cranks are more prone to breaking.
I think there was too much material removed to incorporate the centre bearing.
I am trying to make the engine as close as possible to the engine in my car.
It is close but there are a few compromises.
There were a few different variants of the engine over the years.
Mine was made in 1932.
I think I will remake the inlet manifold, it is ok as a manifold but the shape is not quite correct.
Bert, the lubrication will be splash.
I thought for a long time about fitting jets as the original.
There isnít much room to fit the gear on the rear of the camshaft.
I am fitting dippers to the Conrods, hopefully to create a bit more splash.

wow most parts looks from casting. all with turning the wheels on the mill! Great job. It would be nice to see how you build the new inlet manifolds!

I remember reading someone's book on their 750 special where they noted that the middle pistons were machined a little shorter to allow for the whip in the two bearing crankshaft. With a 750cc side valve special they were happy to reach 75 mph  :)
Best regards

Thanks for the comments.
It is coming along slowly.
I have been making a list of what is left.
There isnít that much to do now.

Tony,
That is quite an amazing project you have going there. A quick question, is that the generator between the engine and the distributor?
