Well things took a different route !! As is the way
I gave one of the engines and my bigger lathe I can’t realistically use to my friends son to get stuck in!
He’s at a good stage to finish the engine and I’ve completed my one first so as to provide dimensions…
Like with most models you find out what you have just at the end !! It’s a Reeves 2000 popular I think they call it , designed as your first engine, I’d recommend it as you won’t get away with sloppy work to get a runner!
