Title: FP 35 head shims
Post by: Paul Allen on January 05, 2025, 05:14:38 PM

Would someone have the dimensions of an early FP 35 Steel piston/liner head shim
inside and outside sizes, what to make some shims for a flying buddy, but he lives a long way away
so I cannot get to the engine. Thanks

Hi, Paul, for the rest of us, what dimensions did you end up with?
Thanks, Mike

Is that a metric grid on your cutting board?

Are ye sure such a search wouldn't turn up a photo of that Air Ministry bloke? Sorry, couldn't resist the opportunity! LL~  :-[ Steve
