Firewall Forward Kit - Propeller

Spinner ( 3 hrs )

Completed Sect 44-03, -04, & -05:  positioning and drilling for mounting.  Needed to trim some for clearance around prop, but template from Hartzell insured good fit (Spinner came with outline marked...slightly more forward than template, but close).   Since opaque (comes with pinholes filled) required use of spherical magnets to locate holes in Front Spinner Bulkhead.  Trimmed cut-out pieces to make Gap Filler behind Prop.  Positioned and drilled #40 holes for rivets.  Since not rotating prop (keep oil from being scraped off cylinders and cams, etc ) I had the pleasure of working from underneath Spinner - not fun, but got  'er done.
Front Spinner Bulkhead has 6 pre-punched holes.  Used
spherical magnets to determine hole location through
opaque Spinnner
6 Spherical magnets in place...ready to
mark hole centerlines and drill.


All holes drilled at Front Bulkhead, and
along rear Spinner Plate
Gap Fillers positioned and drilled for rivets


Working underneath was challenging.
