Overhead Console, Brake Lines, and Fuel Lines

My last post was November 20th and since then work in the shop has been sporadic, not the steady pace I usually have. Visiting friends,Thanksgiving, travel, and all the holiday events create chaos in the shop schedule. We flew to visit Brian and Brandi over in Atlanta. It's a little over an hour flight for us, so not too bad. They usually fly over to visit us but their RV-10 is getting painted and we owed them a visit anyway. Departure was delayed due to nasty cross winds cutting our visit a little shorter than I hoped, but we had fun seeing them regardless. On the flight back home I lost the right vacuum pump, not a big deal since we were VFR. But I can't wait to finish the RV-10, it won't even have vacuum pumps!

We then flew up to St. Louis later that week for turkey and pumpkin pie in the rented Cessna. The trip up was with a 35kt headwind.....ouch. Of course, the winds died down for the return flight so we only had a 10kt tailwind. Baby Ayla slept both trips there and back the entire flight! I had to pick up an IFR clearance on the return trip and, when reaching our destination, leave the beautiful sunshine behind to descend through about 3000 ft of overcast. I was excited about possibly having to shoot an approach, but we dropped out of the clouds around 5000ft. So no luck.

My brake line and fuel line order from Bonaco arrived. The hoses look really nice. The brake line is the standard kit Bonaco supplies for the RV-10 and the fuel lines are custom sized per my order. All of my fuel lines are going to be flexible stainless steel to replace the aluminum tubing that are per plans. This makes the installation easier and should keep the fuel cooler as it travels to the engine. I didn't take any pictures of the brake lines yet...I'll try and remember to do that.

My fuel line measurements are:

QTY 1 - Straight to 45deg - 14.0in Total Length (Fuel pump to firewall)            

QTY 1 - Straight to Straight - 7.0in Total Length (Fuel selector to fuel pump)               

QTY 2 - Straight to Straight - 9.5in Total Length (Each side of fuel selector to Fwd Fuse Rib fittings)
QTY 2 - Straight to 45deg - 28.5in Total Length (Fwd Fuse Rib fittings to wings)

I think these measurements are going to work out really well, but I haven't attached the wings yet for a final fit so don't blame me if you order the same thing and it doesn't work out....: )

Dates and Times

November
Sat 23 -4.7hrs- Overhead fiberglass work. Curved fwd edge molded. Started Bonaco brake line install.

Mon 25 -1.25hrs- Worked on overhead console edge flange

Tues 26 -1.0hrs- same as yesterday, but the opposite side 

December
Tues 3 -1.5hrs- worked on brake line install

Wed 4 -1.5hrs- worked on brake lines and fuel lines

Sun 8 -4.5hrs- Riveted fuel pump mount, worked on fuel lines, cut insulation, laid fiberglass for lip on overhead. A buddy stopped by to help me rivet the fuel pump mount to the lower skin inside the tunnel. We also got some of the fuel lines torqued. Thanks Aaron!
Mon 9 -1.0hrs- sanded and applied layer of build up on one side of overhead

I wouldn't expect much more from me this year. Ayla is going to be ONE YEAR OLD in about a week! Wow already, I know. So were having a party of course and then Xmas, more traveling, food, holiday events, visiting, cold weather.....

Creating molding for where the overhead will flare out at the front.

I'm creating a lip running down the side where an LED light can be tucked inside and the headlines can tuck under.

I cut a piece of foam at an angle using the table saw and taped it into place. A small piece of the angled foam can be seen above. This forms the mold for the fiberglass lay up.

Beginning to lay the fiberglass.

Fiberglass and filler applied. More sanding and filling coming soon.

Torquing what I can on the work bench. I think the stainless steel flex lines are going to work out really well.

Working hard in the shop.

Overhead Console Work

This is only the first step to making the overhead console. There will be multiple steps and parts that need to be made before this thing starts really looking like a finished product. So far it's been a lot of fun. I have some cool ideas for this overhead which is what finally drove me to making my own instead of ordering one. I often have a very specific thing I want something to do or have and when I can't find it on the market I make one. The "I'll just build it myself" decision is usually a very quick one for me to make and I make it often. Most of the time it's furniture..."they want how much for that?!! Wow I could make that for a fraction of the cost and it will last a lot longer! OK I'll just build it" Yep the decision happens that fast and I'm off sketching plans and buying hardwood. Well, the plane isn't any different. If a product is fairly priced and it would be laborious for me to make on my own I'll buy it and not think twice. The overhead though, I had something in mind, some exact details I wanted. Details I would see on the jets I used to work with. So the decision quickly became "I'll just build it" and, so far, it's been a lot of fun!

Dates and Times

Wed 13 -1.5 hrs- removed cabin cover, drilled backup strips

Sat 16th -5.0 hrs- prepped cabin, cab-o-sil gaps, made foam mold and taped to cabin, spray foam filler

Sun 17th -5.0 hrs- started fiberglass for overhead console, two layers
(The times for Sat and Sun are estimates as I wasn't watching the clock. They also include a lot of planning and trial/error time that is normally not done in the shop.)

First I roughed up and cleaned the cabin cover and then filled in voids in the cover with West Systems Epoxy Resin with 205 Hardener and Cab-O-Sil Filler to thicken it up. After filling in voids in the cabin cover I made my mold for the console. The "mold" is made from foam insulation from Lowe's. It's tacked together with glue and then wrapped in tape so the fiberglass doesn't adhere to it. I also filled in the empty space of the forward door frame with spray foam. After the foam dried I cut it to the height of the rest of the structure and then cut out the area needed to install the visor mounts.

I then added a fillet of the filler mixture along the edge of the foam and coated and filled the empty/cut open cells of the foam. I then laid my first piece of fiberglass while everything was still tacky.

I put two layers on the overhead mold and one layer on the sprayed in foam.

Fiberglass laid in place and drying.....step 1 complete.

Ordered the Finishing Kit

Finally the day has come to order the last kit of the RV-10. Of course I still need an engine, prop, hoses and such forward of the firewall, an interior, avionics....but this is the last part of the kit! So last week I emailed my request form into Van's and made it official. The kit should ship out in January.

I requested a kit packing list from Van's that contains a list of all the parts and pieces that come with the finishing kit. I needed this because I knew there were some parts I wanted to replace with nicer stuff. For instance I've heard the wheels and tires aren't the best and should be replaced among a few other things. I started digging into what I wanted to remove from the shipment when I thought I'd ask Ed what he was planning on removing from his shipment. I've mentioned Ed a few times in the blog. He's the guy up north that is at the same point in the build as I am and we tend to share notes. Anyway, he already generated a pretty comprehensive list of what to remove from the shipment and what to replace it with and I am shamelessly going to copy.

What I removed from my Finish Kit:
2 U 15X6.0-6 MAIN TIRE 6 PLY RV-10  (Replace with Desser Retreads)
2 U 15X6.0-6IT INNER TUBE MAIN RV-10  (Replace with Aero Classic Leakguards from Desser)

Starting the Cabin Cover

Fiberglass! I am actually excited to start fiberglass work. I was productive last weekend. I cut out the cabin top and then had the first test fit. I found a lot of places that needed additional trimming with the test fit. With the top back off I trimmed up the noted places of interference and then tried to fit the cabin again. This time it slid right into place, success. On Monday (holiday off from work) I started all the match drilling and countersinking into the fuselage. All in all, the whole process went a lot faster than what I thought and was much easier than what I expected. Actually, it was a lot like wood working but without worrying about wood grain.

I also did a lot of brain storming about my overhead console and how to do fiberglass work. I got a lot of good pointers from a buddy of mine that stopped by Sunday and Brandi pointed me in the right direction to the West System's Website and their products. Most of their products can be bought from Aircraft Spruce and you can do a lot of research and learning on their very informative website. Instead of forking over $1000 for the Aerosport console, which isn't exactly what I want anyway, I want to build my own overhead console. With an order of fiberglass and epoxy from Aircraft Spruce on it's way I hope to start this coming weekend. In addition to the overhead console the cabin cover is going to take a lot of work filling voids and shaping the structure to actually look decent, but I'm ready to get started.    

Dates and Times
Sat 9th -4.0hrs- Cut cabin top
Sun 10th -3.75hrs- Cut and shape cabin top
Mon 11th -6.0hrs- Brain storming overhead ideas, drilling holes with helper Kris, countersinking etc


Marking the places to cut. The existing scribe lines are hard to see and usually not straight.

    Going into battle with fiberglass gear on.

The cabin top trimmed and ready for test fit.

The tools I used: Cut off wheel, Angle grinder with cut off disk, hand held belt sander with 80grit paper, drill gun with sanding drum and 80 grit paper. I mostly used the angle grinder with the cut off disk and the belt sander. The disks I used were standard metal cut off disks from Harbor Freight and it cut right through the fiberglass without a problem.

The leftover trimmings.

I used a pulley attached to the ceiling to hoist the cabin top above the fuselage. Then I would move the fuselage under the cabin and slower lower the cabin top into position.

The cabin top trimmed and in place.....looking even more like an airplane! 

Match drilling to the fuselage and countersinking holes. I used all the normal tools here, nothing special.

I drilled the attach holes for the center post.

Finished Upper Forward Fuselage

I have a lot of things going on right now so working on the plane has moved to the back burner. Building slowed to a near halt and I haven't gotten much completed. And if I don't complete much there isn't anything to write about, and this leads to a lack of posts. I did round up several consecutive hours last Sunday and finished the Upper Forward Fuselage Assembly. I had postponed building this part until I finalized my plan for the instrument panel and all the avionics installing behind it. Once I had the plan I felt comfortable finishing up this section. I hope to get back into the swing of things soon. I have another long weekend coming up, so hopefully I can make some good headway then.

Dates and Times
Sat 19 -1.75hrs- finished rudder pedal install except the brake lines. Installed more access covers and floor panels
Sun 20 -4.0hrs- Prep tunnel close out panels
Install fuel selector valve
Locate fuel pump install location
Make brackets for fuel pump install Measure for fuel lines
Note brake line requirements
Prep order for Bonaco
Tues 22 -1.0hr- worked on side panels
Wed 23  -1.0hr- worked on side panels
Sat 26  -3.0hrs- worked on upper fwd fuselage
November
Sat 2 -1.25hrs- worked on upper fwd fuselage
Sun 3 -5.25hrs- finished upper fwd fuselage

I borrowed this tool from one of our mechanics at work. I would say something like this is a requirement when installing the nutplates for the rear seat closeout panels.

Upper Forward Fuselage clecoed in place ready to drill out the holes.

All riveted together...section complete.

My helper reading the plans.

Panel Plan Rev 3

I rearranged the GTN and mini EFIS. I included a close out panel to lay over the instrument panel, this will hide all the screws and how the instrument panel lays over the lower rail. I also added a little design for fun. I think it's gonna look really nice.

Panel Plan Rev 2

I updated the plan. Rearranged the avionics behind the panel, added an independent mini efis, and changed to the Garmin 650.

I swapped the location of the MFD and Garmin box, which has now changed to the GTN 650 to include ILS and VOR capabilities. I also added the AvMap mini efis/adahrs, it's a standalone system completely independent of the Dynon Skyview and has it's own Pitot/Static input for airspeed and altitude readouts. I also added a second iPad mini for passenger (wife) entertainment. Behind the panel mounted iPad will be a small "glove box" storage compartment. The iPad mounted to the center console will be running Foreflight.

This is a diagram showing all the avionics, instruments, and antennas required for the aircraft. This does not include: switches, probes, lights, or sensors. Note changes: Garmin 650 instead of 635 and added the Mini Efis.

This is a diagram showing the location of each component along with other view orientations.
Note:
- All of the components have been moved onto or aft of the subpanel.
- The VP-X will be mounted on a plate that spans the instrument panel lower angle and sub panel lip. This allows easy access to the component for the large quantity of wiring that will be going to it.
- The ribs do not need to be modified. Only the subpanel will need to be modified to allow the GTN 650 installation.
- The Transceiver and Transponder are mounted directly to the existing tunnel cover side by side.
- The new center console will be made from fiberglass and can be relatively thin since the only thing that is installing to it is the iPad mini.

This is the plan for now...and is still subsequent to change at any time : )
