It is. But the possibility of changing the prop by changing the shaft is a thought too. The reduction case is different in C series but it does not mean the shaft has to be different from engine side. I doubt it would be the same becouse of different gearing systems used by R2800. It is possible to overcome in theory, but I suspect it would need presise tooling as the shaft would have to be dismantled and rebuild and balance problems could have arise.
The real, real question is what was going on with CE P-47 props. I have 3 and let's say 1/2 types of propellers and five confirmed configurations.
I'll try to look for the guy. Thank You for all the help.
The prop shaft that is installed on the 2 types of R-2800 engines mentioned are the same for that series of engine.
In the case of the B engines, there are different gearing on different dash models. The 50 spine shaft is the same though.
It is the same for the 60 spline engines.
The C series could not have a 50 spline prop shaft on the engine AFAIK.
Thus the prop questions of did a 60 spline CE prop hub fit the same blades as the earlier 50 spline hub.
The Aeroproducts series of props used in the P-63, P-51D & H, and even the 2 blade T-28A had the same blade base. There have been Reno Racers that have used 4 T-28A blades on a Merlin.
The Ham Std uses a designation for blade ends such as D. 24D50-XXX is a 4 blade prop with a D blade and 50 spline mount, 23D50 is a 3 blade prop with D blades. The T-6 used a 12D40, 40 spline, 2 blades with a D base.
Wondering how the CE blades were built on the base to see if it is a similar system.
