I just got my baby back from an annual. One snag that was found was the Hartzell C/S prop was rubbing on the spinner and the backplate when at full coarse setting.
At rest there is adequate clearance but no one has ever checked the clearance at full coarse otherwise the problem would have been found earlier !!
I will post a picture when I get home, but wanted some opinions on how to dress this area.
I've read posts on dressing the blades but nothing on the hub of the prop right around the spinner.
There is wear through the paint but no deep grooves in the hub, just looks like scratches on the aluminum. There is exposed aluminum though !
It wouldn't take much effort to smooth it out. My idea was to use 400 grit, 600 grit then 1000 grit wet/dry sandpaper. I could likely keep the affected area to the size of a penny.
This will smoothen things out but how to alodine, prime and paint ? I don't want to paint the whole prop. Can I just use a paint brush to do the applications?
Should I even fart with it or just suck it up and take the prop off and take it to a prop shop ?
Thanks,
Darren
