Spinner nutplates ( 2 hrs )

Drilled #19 clearance holes for 6-32 attachment screws (AN526C632-R8).   Riveted on 6 nutplates to Front Bulkhead, then started on 14 nutplates on Spinner Plate.

Adding nutplates to Spinner Plate (bit more
challenging since remains bolted to Prop Hub

Spinner Gap Filler ( 2 hrs )

Completed Spinner Gap Fillers per Sect 44-06, Steps 1-8, and 44-07, Steps 1-2.  Created Backer Plates with matched curve to Gap Filler.  Riveted to fiberglass, then added nutplate.  Fits well - and looks good too.  Final clearance for Prop to fiberglass edges remains to be done ( need to clamp boards to Prop to move from min to max pitch angles)

Almost ready to rivet to Spinner Plate.

Next -  grind/file  fiberglass edges for clearance to  prop

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.

Canopy Harness and Spinner ( 2 hrs )

Laced wires and splices, then used spiral wrap to gather LED wiring.  Added clear silicone to hold wires to bottom of glareshield to complete Canopy Harness.  Confirmed all connections OK for  LEDs via 9v battery connected to Pins 7&9 (white) and Pins 8 & 9 (red).  Next, measured gap from Spinner Plate to Started Ring per Step 7, Sect 44-02.  Removed slight "dishing" in Plate and gap ranged from 3.033" max to 3.020" min  - so much less than .040" max variation allowed.  Completed Steps 1 & 2 at Sect 44-03 removing Spinner cut-outs.  Used thin diamond encrusted wheel on dremel (cuts fiberglass like butter !).   Trial fit on Prop shows more material to remove for clearance.

completed canopy wiring under glareshield.

Spinner came marked for cut-outs, but
 I used template Hartzell sent via email. 
Very close, slightly less at top.

Trial fit.   Some clearance needed, but close

Avionics

LED lights under Glareshield & Pinch Welt ( 3 hrs )

Installed "pinch welt" on edge of glareshield.  Pleased with fit (good grip) and appearance.  Purchased from Classic Aero Designs in 60" length for $7 - used approx 50".  Cut the Red LED and White LED strips to 26.5" (at designated cut line on printed circuit).  Purchased these from PilotLights.net.   Connected to Canopy Harness per Stein Air schematic (to work with PWM dimmers and Garmin GAD27 - see Jan 11 log).  Still need protection and retention of butt splices, but almost done with Canopy.   Temporarily mounted S-603 Front Spinner Plate to prop hub per Sect 44-02.

Red and White LED strips installed, connected via butt splices
 to Canopy Harness.    Bottom view "pinch welt" on edge.

Stein Air provided revised schematic to show wiring
 for separate Red and White LEDs

Propeller Mounting and Alternator ( 3 hrs )

Torqued Propeller Mounting studs to 65 ft-lbs per Table 3-1 and Fig 3-2 ( Step 1 = 40 ft-lbs, Step 2 = 65 ft-lbs) in Hartzell Prop Owners Manual #115N.   Safety wired and applied Torq Seal.  Adjusted alternator belt tension per Maint Procedures Sect 5, page 5-8 in Lycoming Op Reference Manual for IO-390 series.   Set by slip torque method to 145 in-lbs (midway between 132 to 156 in-lbs for New belts. Note: Used belts set to 84-108 in-lbs).  Safety wired lock bolt.

Works well, but wow is this tool expensive.

 

 

added torq seal

alternator belt tension set, so torqued and

Propeller mounted ( 4 hrs )

Safety wired alternator attach bolt per Sect 51-06 (waiting until after Prop installed to tighten Alt belt - so I have a lever to resist turning engine while using the torque/belt slippage process).    Re-opened Propeller box (rec'd late 2017 since ordered same time as Engine to get discount Vans offered) and moved to floor with wife's help.  Mounted Spinner Plate to constant speed hub - torqued to 21 ft-lbs per Table 3-1 in Hartzell Owner's Manual.  VAF has good recommendations from builders on how to remove plug in crankshaft (oil passage to CS prop)  - and it came out easily with slide hammer.  Used engine hoist w/ straps to lift/position Prop to install per Sect 44-02.  Tightened 6 places, but didn't torque/safety wire ...yet.   Reference data on Prop:  Model No. HC-C2YR-1BFP/F7497     Assembly Serial No. NS3530B    Blade 1 L82636,  Blade 2 L82641   ( Low pitch 13.6  High pitch 35.0)

Alternator  safety wired...
Belt tension not yet set for other bolt

"Thar she be..."

Serial No. NS3530B.   (Plate says A-2424 Rev 0 )

Prepping to mount Spinner Plate

Hartzell PC10 TC P920   HC-C2YR-1BFP

        Sticker confirms documentation:
Blade 1 Serial # L82636, &  Blade 2 Serial # L82641

B-2428-1  Rev AS   SN171765.

Confirmed O-Ring in place as mounting Spinner Plate

Torqued Hub Clamp Bolts to 21 Ft-lbs per Hartzell manual

Followed VAF recommendations to remove
plug  in front of crankshaft.   Came out easily...
with couple ounces oil spilling out.

Nancy helped secure Propeller. 
It's a lot easier with two people!

Yay!   It fit....

Tah Dah !   
Looks big since close to camera...
