I guess it’s the blades that are wrong for the Hurricane – pedantic point, but the hub is probably right – hence my follow up question to check – 23E50 on the Hurri, just like on a DC3?
More pedantry, Camblobe – the P-47 would have a 24E50 (four blades)
Thanks Camlobe
So it’s fair to presume from this that the CCF Hurricanes, having Packard engines, used 23E50’s?
Oh, and it’s also fair to say that our Whirlwind (having 4,000-series RH rotation DH CW props on a RR fine-spline SBAC4 shaft) had a licence-built equivalent of the 3DX40?
Hope you’re not serious, Bruce!
Suggestion
Why not have a sticky thread called ‘idle speculation – warning, may contain nuts’ into which theorists can throw all ideas and satisfy the desire (which we all have from time to time) to throw in theories based on what we know.
This thread can run forever, can be ignored at will – and anyone tempted to do their speculating on a thread like this one can be immediately directed there.
My guess at the hub type would be 23EX.. 2 = hydro, 3 = number of blades, E = shank size X = accepts a ‘foreign’ (ie UK) shaft size.
Any takers? Anon? Anneorac?
..cue debate over who has the bigger shaft sizes!
Thank you Eddie, that was staring me in the face but it takes someone who knows stuff to point it out!
According to William R Dunn (who flew CCF Hurris), in his autobiography ‘Fighter Pilot’, Hamilton Standard wouldn’t guarantee these props when enclosed in a spinner.
So, next question is – what was the hub type / blade number? :diablo:
Actually, I completely forgot – if you go on the Whirly site as per my signature, there’s some Hurricane woodwork that might be of interest to you.
Gas patches?
Thanks for the background – sounds like an interesting project. WARNING Hurricanes are fiddly!
I’ll see what I can come up with next time I’m up at Gransden 🙂
It’s true, the circumstances of Robs escape still amaze me weeks later.
Surprised to see a s***e paper like The Guardian running such a good article, thought they’d be too busy blaming the Tories for the riots:dev2:
So.. you thought wrong. I suppose the moral is read the paper before calling it names – especially when it means bringing unecessary political prejudice into a forum that is better without it.
Thanks Andy! 🙂
Hi
As an apparent ‘newbie’ – can you tell us more about your project? I am particularly interested, for reasons that might become clear if you look at my previous posts..
We might be able to help.
Cheers,
Matt
Hi Andy
Good stuff – funnily enough I was looking for somebdy to talk to from that project! I have PM’d you some prop hub questions.. can you guess why?

Excellent idea. It’s not all about expensive ‘aviation grade’ materials or components either. There are savings to be made (especially, but not uniquely) by going elsewhere for bits and pieces outside of the aviation world. For example – buy protective tape to put under fabric from Staples, and not a ‘well known aviation stockist’ and it’s less than half the price. I’d go further and suggest that tips like this, as well as guides and ‘how tos’ are also put onto this database.
PS – Mike, can these dished holes be up to 5 inches across? If they can, I am VERY interested as well.
That’s a fair point. ‘Cottage Industry’ was the wrong term for me to use.
