We've moved!

We finally moved to the new house today.
I seriously considered the suggestion on VAF to move the airplane myself, but since we were hiring movers for a lot of other stuff anyway, we just had them take it. They did a pretty good job, and the only thing I had to ask them to do differently was to lay my flaps flat on the truck floor instead of on their trailing edges.

Goodbye, old workshop! You served me well, but I shall not miss you.

A few of the smaller parts will still need to be taken by car (ailerons, vertical stabilizer, rudder, etc.), but all the large parts and a lot of the small stuff is already there.

Now on to putting the workshop together again to build on!

Fuel tank assembly complete

The tank comes mostly assembled, with a few finishing items not yet done.

The first task was to remove the tanks, which was easy but time-consuming (lots of screws and bolts):
Tank removed from the right wing
riveting the bearing:

I installed the skin nutplates, including those that are only called for much later in section 44 (didn't find a reason not to):
Nutplates riveted to right tank
I bent and cut the fuel sender arms, only to find that I, like others, had screwed up and cut it too short without realizing the arm is supposed to go through the sender. Ordered new arms, re-did it - correctly this time:

Fuel senders, VA-261 pickups, drain and other hardware for the tank
I read up a little more on the fuel system and realized that, if I decide to use a FADEC, I may need a fuel return line. Much easier to do it before installing the tank, so I did some careful planning - some people from VAF pointed out that it can't be too far aft or it'll get in the way of the wing attachment. I got two more VA-141 brackets for this, and used a 3/8" NPT tap to make sure I could screw VA-261s in from the other side. I then used those to drill the holes on the side of the tank, next to the vent line:

We did the drilling with a vacuum cleaner extension (piece of conduit taped to the tip of the vacuum) strategically placed to catch aluminum bits, which greatly minimized the mess inside the tank, but we still had to later move that extension around to clean up all the bits that flew around the tank.

When I drilled the left one, I realized I, too, had made a small mistake - notice the J-channel from the tank's structure shows through the hole - the hole was too close to it, so I had to shave off the corner of the J-channel to ensure the VA-261 would still fit.

On the second tank, I drilled the hole a bit further to the side, and instead trimmed the bracket itself to fit, this time hitting no obstacles inside:

Finally, I installed the senders, return bracket, pickup, and drain, using tank sealant and thread-locking sealant. For the fuel return brackets, I used CR3212-4-2 rivets:

We then installed the Newton fuel caps - even in the garage, the Van's caps were annoying enough to open and close to make me want to replace them:

Cleaning the excess sealant from the fuel cap bracket the best we could

Last but not least, someone at VAF called my attention to the fact that I hadn't left a ring terminal around one of the fuel sender screws, so after the sealant cured I checked the ground continuity between the fuel sender plate and the skin, and it seems to be conducting just fine.

Among the next steps are leak-checking the tanks and reattaching them to the wing spars.

Time lapse:

Total fuel tank time: 12.1h
Total fuel tank rivets: 30

Tailcone mod chemicals

Over the last few months, we did some small tailcone mod tasks.
We used Clickbond CB9120s for running conduit through the tailcone:
including one vertically at the bulkhead to run the pitch trim/ELT cable down:
Vertical wire bundle attachment in place

Conduit attachment brackets in place along tailcone
More recently, since the sealant I purchased was getting close to expiration, we attached the NACA vents and static ports with sealant:

NACA vent clecoed in place with sealant

Static port clecoed in place with sealant
Riveting those will have to wait - I was using a borrowed compressor which I had to return, and I won't get a new one until we're settled in the new house.

Time lapse:

Total tailcone time: 220.9h
Total tailcone rivets: 1826

Building paused (for a good cause)

This is not the usual airplane-building post. The good news is that I've bought a house!!
This means several things: it means that I've spent the last month doing copious amounts of paperwork, that I'll spend the next two months preparing to move and moving, and most importantly it means that I can't afford to order the fuselage kit right now, so the building is paused for the time being, and I'll post just a few videos that I already had in the queue.

 It also means that I'll have a larger garage for working on the RV though, so stay tuned :)

Bottom wing skins: pitot mount and flap gap fairing riveting

I replaced the bad rivets behind the inboard bottom wing skin with CR3212s (and one CR3242) as recommended by Van's, for much better results:

I also used MSP-42s for the other rivets that would be nearly impossible to reach with a bucking bar:
Pop rivets for the inboard portion of the flap gap fairing

as well as the rivet that sits too close to the bracket from SB16-03-28 (which Van's was very kind to address during the quickbuild process, but left me without access to buck that rivet):
Pop rivets near the SB16-03-28 bracket
My OCD side dislikes having two types of rivets on the same line, but there's no way I'm going to remove and re-set all the solid rivets :)

I then continued with the Gretz pitot mount installation by match-drilling 3 of the backing plate holes through the skin from the inside, which was annoying and required 2 people - one with the drill and another with a mirror to position the drill bit into the hole using a mirror:

With the two holes near the rib, I positioned the rib bracket against the backing plate and rib (using the mirror to get the right height), then match-drilled again through it. I removed the skin and match-drilled the other 2 holes of the bracket through the backing plate and the 3 1/8" holes through the rib:
Rib bracket match-drilled to backing plate
I clecoed the backing plate to the skin again, match-drilled the remaining holes and marked the main mast hole:

To cut off the mast hole, I then used the Swiss technique - drill it like a Swiss cheese :)

I then finished it off with the dremel (cutting and then grinding), through the skin as well as backing plate and washer plate (which I had to trim down for the rib bracket to fit):

I then test-fit it again in the wing, and also determined that there's enough wire in the heat regulator box to reach it from a couple of ribs inboard (which is good to minimize interference with the NAV antenna and magnetometer on the wingtip):
Wires from pitot heat regulator to pitot tube
I also drilled and deburred the other cover plates:

It was then time to deburr the hundreds of holes on the bottom skins, as well as their edges and the corresponding holes on the ribs - no photos of that, but it's most of the time in the time lapse below.

Time lapse:

Total bottom skins time: 34.9h
Total bottom skins rivets: 406

Electric aileron trim assembly

I match-drilled the trim assembly to the cover plate:
Match-drilling trim assembly screw holes into cover plate
then dimpled the holes, installed nutplates and screwed them together:

I ran the servo to find the center position, then marked it on the links:
Center position marks on the aileron trim links
The next steps require the aileron pushrods to be installed and adjusted, which can only happen after the tanks are in place, which in turn is pending on installing the fuel return brackets, which are pending an order for 3/8" NPT tap.

Time lapse:

Total aileron trim time: 5.6h
Total aileron trim rivets: 12
