FWF Section 44 Spinner and Propeller

RV14 Build May 21

Spinner and Propeller

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.

FWF Section 47 Baffle

RV14 Build March/April/May

Baffle

I knew I wanted to anodize the baffle it just took some time to find a local place. Once I did, I started to prep the parts. Cut, drilled, and bent everything I could find in the plans.

Using the template to make bends.

Did the same on this part. Trial fitting the whole time.

Stack to drilled and finish parts.

Drilling the air filter box

32 parts headed to the anodizer

Got the parts back and started to assemble. Some of the clearances are tight so riveting was harder than expected.

Coming together.

Applying RTV

Looks good!

Cutting the air filter box to final size.

RTV the screen in the alternator fresh air vent.

Just a cool pic.

Test fitting on the motor.

Finding and trimming he clearance issues.

Getting close.

Some more trimming.

FWF Section 45 Cowling: Bottom Cowl

RV14 Build April

Cowling

After waiting months I finally have the bottom cowl and I promptly made a mistake. You aren't supposed to trim the side of the cowl just yet, you wait until the top cowl is on to help with the alignment. Hopefully this doesn't mess me up in the future.

Taped the trim lines to make them easier to see when cutting.

Trimmed to the lines.

Just a cool shot I think

I spent WAY too long trying to get this to line up to drill 2 holes for clekos. Im not use to reading the instructions again after free wheeling the avionics.

Bottom Cowling 4.5 Hours

FWF Section 44 Spinner and Propeller

RV14 Build March/April/May 21

Spinner and Propeller

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.

FWF OP 62 Kit mods for EXP119

  

RV14 Build March/April 21

Exp119 Mods

Starting off with the mods is the cowl flap or exhaust tunnel flap. Simple enough, gather the parts, prime, assemble.

Prime

Assemble

Adding nutplates and cushion clamps.

Time to drill the nutplate locations.

Drilling. The hard part is how do you dimple the skin. I pruchased a bit that fits into the rivet gun that will hold a dimple die and if I drill a hole into a bucking bar to hold the other end of the dimple die I can smash it into submission. Or I bought some oversized rivets/oops rivets for AN-2 with smaller heads than -3 that will just night a slight countersinking. still TBD.

Nutplate loctions.

I was back and forth on adding another firewall pass through like the one above it or the special one that hold 2 cables. In the end I decided to use the special one with the kit.

Fitting the snorkel is detailed in the whole baffle section but here is the part that is OP62.

The snorkel interferes with the cylinder 2 oil return line. So disconnected it for now.

After I fit the snorkel I realized the baffle was pushed out by the cylinder heater elements. So I removed the baffle and trimmed it. of course I had to start from the beginning on fitting the snorkel since everything shifted.

Finally a good fit.

Drilled holes for clekoes and I fluxed the top abne bottom of the snorkel parts together. 

The fuel flow sender mount plate.

I had to add spacers under the plate before the cushion claps. This allowed the sender to sit away from the oil sump a little better.
