| Subject: | Fitting The Spinner To A Hartzell |
Listers,
Hartzell recommends a minimum .1" clearance around the prop blade for the spinner.
I did that exactly, but the prop would still bang on the spinner at full
pitch. I had to hog out to .25" to keep the clearance at .1" at full pitch.
It looked stupid having such a large gap in one area only so I evened it up to
.25" all the way around. But now it kind of looks like I made the holes too
big. I just can't recall seeing other installations to know if my .25" is "too
much". Anyone have any pics or thoughts on the clearance using late-model Van's
CS spinner and a Hartzell, particularly the 72" paddle blades I've got?
Thanks!

That is an important consideration. To mount the cowlings, though, you have to
have the spinner on. With a CS prop, the spinner mounts directly to the prop
and not the crankshaft so you have to mount the prop to the engine to get the
spinner in the right place.
Now I've just got all that much more incentive to get it in the air!

Matt,
I've seen others who made a backing plate mockup out of pvc and plywood. I
didn't go to that extreme, I just was very careful while massaging the cowl,
and then immediately removed the prop when the cowl fitting was complete
because visitors to the shop, for some reason just can't resist the
temptation to wiggle the prop.
