I thought it might be a cover over an air cond. pulley off the crank, but I dont see the other pulley or belt mounted down below. I am baffled. Thanks ,, T.C.
You probably have little experience with spinners on your 985's or 1340's because you were using them as god intended (working them) and not dolled up for fly-ins
Am I talking about the piece you are refering too? Also - Jungle's answer, if different than mine is obviously correct.

Eventually he took the spinner off (Waco's look better without them) and this assembly came off.

My question is, what practical value to spinners have in the first place? I believe they are meant to facilitate cooling, but it certainly did not work that way in the Waco.
Also, Air Tractors have speed rings I believe - did that help cooling? Did you guys running the big radials ever experience cooling problems in your flying?

These "speedrings" on the ag planes were just that, A ring around the top of the valves. On the ag planes they were, to me, more trouble than they were worth.

Alright T-Cart - Jungle is screwing with our minds now.
I am pretty sure I answered T-Cart correctly. I have NEVER seen a spinner assembly like this. Jungle, please explain if I was correct, and also how and why this spinner assembly works.

I guess it is just personal taste, but with some exceptions (Spartan 7W, Staggerwing, Howards) I like the "naked" look with no spinner and the counter-weights hanging out. For spinners, I like the look of the larger spinner better than this - seems more substantial. Thanks for sharing Jungle - never saw a spinner like this!
