Looks great Matt. Won't be long and it will have air under it. Nice looking
airplane.

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!

Hi Matt,
I'm not sure where I got the idea, but I clamped a padded 2x4 to the prop
blade so I could rotate it through it's normal travel. Then I, cut'n fit,
cut'n fit, cut'n fit, until I had what appeared to be adequate clearance
between the spinner and prop blade. I didn't know about the 1"
requirement - sounds like a lot. Hmm...now I wonder if I have enough
clearance.

Ooops! I just now noticed the 'decimal' in your post - that changes
everything.:)

Matte,
When building my 10, I found out (after) that Hartzell has printable templa
tes to make this cut in the spinner.=C2- William Curtis has one listed fo
r the 10 http://nerv10.com/wcurtis/9XOther/8068D_Vans_Hartzell_Cutout_Templ
ate.pdf
and I'll see if I can dig one up for your application.
