I messed up my cut on the spinner gap seal so I had to lay up some fiberglass and carbon to build us layers for a new part.

After it cured.

Then I traced the outline of the opening

Cut the piece to the correct dimensions this time

Clamped and drilled the gap seal into place.

Then I trimmed all the way around the prop for inferences and making at least 1/8 gap at all pitch settings.

I am having some issues with the alternator alignment and have measuring and looking at it. The alternator seems like its 1/32 of an inch aft and tilted down in a different plane from the main spinner ring. Not sure what to do here. tbd.

Front and rear bulkhead are installed. I marked them with an X to keep there orientation after drilling the spinner.

I measured the drilling line and used the pre marked location on the spinner for the rear bulkhead, for the front I put magnets inside and used magnets to locate the drill location on the outside.

Made a small cross under the magnet and drilled hoping for the best. Some of my underside magnets had moved and my drill holes were a little off. To help this not be a problem I drill with a 3/32 first, then make sure I find the hole and then drill with #30. This way any off center drilling will be taken up by the #30 hole or the #19 hole later when drilling for a #8 screw.

All the #30 holes drilled.

Final drilled the #19 for the #8 screws.

Marking the prop gap filler.

After cutting out the prop gap filler I didn't like the fit or my cut lines.

So I decided to lay up a panel of fiberglass on the spinner to make a new prop gap filler. I put down packing tape and then waxed the tape. Using the spinner as a mold. The spinner is really thick so I went with 6 layers of cloth and figures I can sand down to match.

Making the prop gap filler baking plate.

Adding a slight bend to the backing plate.

Drilling the bulkheads for nutplates.

Starting off this section is fairly easy. You make the rear spinner bulkhead by match drilling and then removing the center of the plate. I used a jigsaw, drill bits, and sand paper of this.

Match drilling

Primed and assembled.

Next I made the cutouts on the spinner of the prop blades.

Cut and sanded. The cut lines came marked on the cowling

Installing the rear spinner bulkhead. You can see on the prop hub the bold closest to you doesn't have a recess around the bolt, this is what orients the prop on the craenkshaft.

I didn't get a picture but the prop can only go on 2 ways. Around the studs 2 of them don't have recessed areas and they match with the crankshaft. Working alone today to engine hoist to do the heavy lifting and alignment of the holes.

This prop wrench from AntiSplat is amazing!! Pricey but well worth it.

Prop is on. By myself this took about an hour to do. I did add 120lbs of sandbags to the luggage area to help with the balance.

Marking the distance between the rear bulkhead and ring gear. All mine are within 1mm

Pushed the spinner on. Marked where the front and rear bulkhead are, sanded out high spots, and added a layer of epoxy. I died it white so I could see where I was putting it better.
