More electrical…

*sigh*

Lots of work but little to show for it.

Electrical work takes time and in the overall scheme of things, it does not have much visual impact. You do TONS of work with little visible to show for it. We have a new battery, flaps, flap indicators, trim indicators working, boost fuel pump, master switch, circuit breakers, auto pilot controller, Skyview three know controls, 12V power plug, interior lights, and a bunch of other stuff.  BUT IT DOES NOT LOOK MUCH DIFFERENT!

Oh, Well, back to work.

Paneling…

Wow. What a journey!  Here is what we have today:

All the parts are in, but we are just starting to wire the stuff. Easy to say, tough to do (at least for me) But we will move forward.

One of the design features will be the ability to pull the panel section (left, center, right) out a bit to work behind. To help with that, we have built extension to put in place while we are building to make sure the wires are long enough after installation. Here is how we did that:

These brackets are just to support the panel during construction.  We will move the panel back, and anchor the wires when completed.

Electrical Work…

We are underway on electrical and things are going well.  Long wires are run, and we are starting panel stuff.  we installed fuses and circut breakers in this project. Two fuse boxes (essential bus and master bus) that are not available in flight. If you get an electrical short in flight, wait until you are on the ground before trying to fix it. In-flight fires can ruin your day.

The fuse blocks are mounted on a hinged flap that can be lowered by removing two screws.

We also have 4 circuit breakers on the left panel, for alternator field, flaps, trim, and auto pilot. These are the kind that can be manually pulled in case of runaway.

Here is a tip for electrical work.  Buy a handful of alligator jumper wires for testing and fitting. These are pretty cheap, and will help with testing before installing.

a 12V electrical test light is also a good purchase.

Gary Passed Away…

Gary Anctil was my friend.

He was my friend for the last 7 years. For the last 5 years, we had a deal.  I’d be his computer guy and he would be my A&P/IA and my mentor for building my RV-9A.

Gary Anctil, pilot, friend and mentor passed away last week after an accident.

Gary was a difficult man to know, but an easy man to remember.

He was a soldier, a spy, a smuggler, a scoundrel, stubborn and secretive.

He was a pilot, a mechanic, a craftsman, a veteran, a voting member of the academy, and finally I think, a scholar. He was the guardian of a little piece of military history as the owner of a Cessna L19E Bird Dog.

He took his responsibility as a caretaker of the L19 very seriously and worked hard on all the details that were true to the hardware, but more importantly, true to the times when it was in service.

Finally, Gary was a teacher.

He taught us that a Hawaiian print shirt was an appropriate fashion statement for any occasion.
He taught us that passion in life was a good thing, but that too much passion was not. He also taught us that passion does not mean anger.
He taught us to say what you mean, and mean what you say.
He taught us that service to your country gives you the right to question where your country is going.
He taught us to remember the past, but don’t try to live there.
He taught us not to fly an Aeronca L2 in IMC (it pits the prop).
He taught us that helicopters are a collection of parts flying in close formation waiting for something bad to happen.
He taught us the patience of a craftsman, and the impatience of a computer user.
He taught us that no man is an island.

And now he teaches us that life is short and uncertain. To live everyday as if it is your last. Be good to your friends and be sure to say thank you.

Thank you Gary. We will miss you.

My Family Gives Me Wings!

And friends too…

Well, we have now installed the wings for the first time, and I’m a pretty happy guy!  After many weeks of worry (as usual) we have spent the day at the hanger and we have passed a BIG benchmark: Wings on!

Last Saturday, I invited a bunch of family and friends to meet Tom and me at the hanger for a good old fashion wing raising.  What is a wing hanging?  Well, one BIG step in building is to set the wing incidence and drill the attach bolt for the rear spar.

Fuse ready for Wings

 

So, Tom and I arrive at the hanger real early and move all the stuff out of the way. we roll out the wings in the wing stand and center the fuselage in the hanger. We then level the entire fuse left and right and front to back. We install temp legs on the fuse stand to be sure it stays that way.  We then laid out the wings and waited for folks to show up.

We did not have to wait long and all the folks were ready to insert the wings, level them, set the sweep and clamp the wings in place.  After double checking everything, we are ready to drill the read spar. Volia!  Wings set.

Wings Installed

So, what do you do after all that? Well, you REMOVE them off course. The wings will not be installed for the last time until after the plane moves to Camarillo.  Here is how you remove wings:

Panel Planning Post Possibly Perfect!

*sigh*

We are getting into the really tough part.  Planning the Panel.  I see many panels, and think how cool they are. How complex they are. How WAY complex they are.  I want a simple airplane that is easy and fun to fly, and I can go into the clouds with no worry, and if things get tough, a simple panel will bail me out.  I’m not building the space shuttle. I’m building a cool two-seater that is Cessna Safe!

Panel Playground

OK, I believe the planning will be complete, not when I run out of things to add, but rather I will run out of things to take away. Anyone want to buy a Hobbs Meter?

We have decided not to go with the EXPBUS and instead go with 90% fuses. I’ll still use circuit breakers for flaps, trim and autopilot. It will be the kind of circuit breaker that I can pull to disable. This will give me one last change to prevent a runaway motor.

Main Bus and Essential Bus fuse holders

It is funny, that I’m ready to build the plane the way I want to build it, but when an onlooker says “Have you thought about X” I have a knee jerk reaction to say “I’m building the way I want”

*BUT*

The reality is that I did NOT think about that, and it is a good idea to at least thing about this stuff. I make it a habit NOT to try to make a decision right there, but rather really think about the comment, and THEN make a decision when I weigh all the options. We are in the process of thinking about:

  • Fuse vs Circuit Breakers vs Fuseable links
  • Essential Bus and Main Bus and Master Bus and Ground Bus
  • Wire access
  • Switches
  • Equipment I bought and can leave off (How many Hobbs meters does a plane need? How many timers?)
  • Cutting ALL the panel holes first time out.

We will soon be taking a break from all this and fit the wings. Wow! The Wings!  Silver Wings! Laughter Silvered Wings!

Jaws!!! A bit of add-vice….

A good vice has a clamping jaw that can hold ANYTHING while you wail away on it. The problem with that is the damage that can be done to the object clamped in the vice.

Here are my vice jaws:

Jaws of Death

To prevent damage to small items, I cut a couple of pieces of 3/4 x 3/4 aluminum angle (the square kind, not the structural kind ) to clamp without damage

The problem was that these babies were ALWAYS hitting the floor while I was trying to insert the work. So, a quick trip to the local stationary store got me a rubberized magnet (used to make business cards into refrigerator magnets) that I cut into a couple of strips and glued to the top of the jaw protectors. Voila!

Cool.

 

Controls are in place…

We have the engine controls in place. We installed the three stooges today: Throttle, Mixture and Carb heat.  Actually the flap switch is installed too. Just like in a Skyhawk. Easy to access and use on approach.

Panel Again

With the controls quadrant installed, we have run the control cables out through the firewall, and we hope they are long enough to reach the carburetor.

We are also continuing to install electric wires. we have the ANL fuse on the fire wall, we have the master and start relays in place. We built the battery to relay wire (4 awg), and the master relay to ANL fuse wiring. We have cut several holes in the right side panel like 2 –  12 volt power plugs,  the heater control cable, the defroster fan switch and the two dimmer control switches. We are still planning the left side. We are still not sure how the fuses and electrical controls will work.

We also installed the mount for the tablet to be installed on the right side.  This will be the backup EFIS and flight planner, including an AHRS insterface with bluetooth connection.

With electronics for tablets growing at the same rate as microcomputers did on the 90’s, we figure we will have double the performance and capability of the backup EFIS every 2 years.  We should plan on making that an easy upgrade.

Let me get this straight…

*sigh*  I goofed.

 

No easy way to say this, but I goofed. And I thought BIG TIME

We drilled the elevator horns on the tail by aligning the counter weights to the horizontal stabilizer. Straight tail, straight elevators, right?

Nope. Wrong

Somehow, I managed to get the two halves out of alignment. Only a degree but my hanger partner (who built a 7) told me that will never fly right.  Now what the heck am I going to do? I drilled the hole!  Move the hole? Hmmmm…. not enough room.  Replace the horn?  OUCH! I’ll have to re-skin the tail!

Turns out there is a simple solution.  Take the entire tail over to Walter the Welder (Yes, his name really is Walter) and have the hole filled. Grind it smooth, repaint and I’ll have a second chance.

Lost a little powder coating but Walter did a GREAT job of filling.  I filed it smooth, then took a scotchbright wheel to it, and cleaned with MEK.

My guess is that I’m not going to be able to do that more than once, so I better be CAREFUL this time.

 

 

 

 

Geek Test..

This is not exactly related to the building of N18TD, but it is related to a pet peeve of mine.

Since it became in vogue, may folks are calling themselves “Geeks” who are not really geeks. A little insulting that we who are geeks had to suffer the bad times, to have others jump on the band wagon when it is the good times.

So, here is the ultimate Geek test:

1. Have the subject read this aloud, and ask them not to say anything when they are done:

“There are 10 types of people in the world, those who know binary, and those who don’t”

2. After they finish, Have them read it again out loud.

Done!

True Geeks will be able to identify the results of the test. And identify a true kindred spirit.
