Hi !
No I dont think so, the designer of this engine was Karl-Erik Olsryd. He lived in Sweden
I think he was at least 70 years old 1996, when he did this castings.
He made a lot of engines the most known was a 9 cyl radial WRIGHT engine.

Very nice work! You are really making some headway.
 
Very nice work!

Can you tell me about your valve cages. Are they bronze? Pressed in place or held with adhesive like Locktite? I'm interested to see your chamfering tool & the valves when they come along.

ps - just for interest, a 1/4 scale Wright J5 9 radial of the same designer is being built in Japan. He mentioned he had the casting & plans about 10 years before starting.

Thanks.
The valve cages is made of bronze and held in place with a nut. Probably I will fix them with Loctite 271 when I assembly the engine.
The Wright Radial is very nice engine. I have the drawings but I never bought any castings. I regret that now.
I bought the castings for the Boxer engine at Christmas time 2016 from a guy that had them for many years, but newer start machining them.
