Cowling at 95% done

Postby bruceh » Sun Jun 02, 2013 8:13 pm

Its been pretty quiet on here lately. Here's what I've been up to the last couple of months. Got the last of the cowling interior sealed up with epoxy, so I riveted on the hinges.

Image

Just a few more things to do: fill some places on the inlets, add the nutplates to the inlets, fill around the oil door and side hinges with some micro. Sand (repeat ad nauseum), then seal and prime for paint on the cowling exterior.

Next up is the Filtered Air Box, engine control lines, fuel lines, engine wiring, alternator, starter, and a prop. After that it is instrument panel and interior before we go find a hangar at the airport. Hoping for the end of summer to be at the airport.

I got rid of the pink, but now the dust is white (and everywhere).

Image

I put a couple of coats of UV Smooth Prime on the cowling, then sanded it down fairly smooth. I rolled on a couple more coats and now I get to do it all over again. This filler/primer is easy to sand, but it creates lots and lots of dust. I'm probably at the 98% done point now.
I haven't decided on paint, so I'm not going to shoot any epoxy primer or paint on there just yet. I also have to get the reflective heat shielding added to the interior of the cowling.

In other progress news, the engine is almost completely wired up. Just a few more wires tonight should complete that work. I did the P-mags last night.

Firewall forward work left is down to installing the fuel hoses and getting a propellor.

Instrument panel is on deck!

Done with the endless priming and sanding! Smooth as can be now.

Looks like it is ready for the propellor.

My wife had a total knee replacement. She has moved to a cane to get around.

Bruce, We hope your wife's progress is good and complete :!: Your cowl is really smooth 8) Progress on your project is great :!: I found that painting my airplane before final assembly has merits.l People who fly their airplanes nude(with out paint) usually end up flying for a year or more and then have three month or more period of down time for painting. I have to believe in the long run it is cheaper to paint before final assembly 8) You are supposed to use new wing bolts if you fly it first and that costs something. There are probably some other parts that you end up replacing in the process of dismantling for painting. I was really glad I got my paint before first flight. My wheel pants, gear leg fairings. and wing tips were all bare. It wasn't a bib deal to take those off and take them to a paint shop 8)

Nice work, Bruce! I've been following your progress, and it all looks really great. Tell us again, what do you have in mind for a prop?

I've decided to get the Sensenich Ground Adjustable prop that just came out for the IO-320.

Another -9A owner here at Ramona just put one on his plane and is getting some good extra speed from it over the metal Sensenich which was limited to 2600 RPM.

I like having the ability to fine tune the pitch to meet your needs for speed or climb and to get the most RPM out of the engine.

Bruce,

Will you do my hinge pin covers too?

They look great!

Another way to do the hinge pins for the cowl sides is to run the hinge pins in from the cockpit and fasten them in the cockpit. It doesn't work on the RV-4's but is great on side by sides.

I thought about the interior pin concept, but after looking at it I couldn't see how to make it work without a lot of design and effort.

Making the hinge pin covers was not that hard. I put a bunch of photos of the process up on the web site. Hardest part was finding the right shape to use. I ended up using a guitar pick shape. I wanted some sort of triangular arrow, but having enough space to put some nutplates behind it dictated the overall size.

BSwayze: How is your cowling work progressing?

I have a good friend that did the internal hinge pin and after 7 years or ownership or so he has decided its a PITA.

Your cowling looks quite lovely :thumbsup:
