Painting the instrument panel

This is BIG day for me!! The painting of the instiurment panel.

First it was sanded with 220 grit paper to roughen the surface.

Next is a good cleaning with Bonderite to prepare it for the epoxy base coat

The Bonderite cleaner is essential to etch and clean the Aluminum prior to painting.

The flat black panel is done…

Installing the radio cans

Installing the radio cans is simple and straight forward, but it does require a little thought into what kind of presentation you would like to display.

Typically, radios are installed with the fascia of the radio on the surface of the panel. Trying to just drill holes in a side plate is harder than one might think because of alignment of each side, trying to be perpendicular to the face of the panel, and where the mounting holes are in the cans (the are all different).. I find this method unacceptable because additionally, each radio or piece of equipment has a different depth of its face which (to me) unintentionally makes the panel look a bit disorganized with each piece of equipment just sticking out into the cabin a different amount.

I prefer to recess the cans into the panel to provide the exact amount of exposure necessary so all radios and equipment have the same exposure height for a nice organized look.

Actually, I found a very easy and fast technique for installing the cans which also ensures all the cans are perfectly perpendicular to the face of the panel. Once you decide on the amount of radio exposure desired, use this method to mount the radio cans. This is post from April 2016 when I used the same method for mounting the cans in my LongEZ. http://nickugolini.com/blog/?s=panel+mounting

Personally, I prefer using rivets instead of screws to attaching the cans to the side brackets which prevents any movement of the cans

Radios in place to check for the look I want.

Normally the Garmin has a .850” exposure. The Audio panel had a .780” exposure which would be a .070” mismatch. The Dynon sub panels have a .150” exposure. Here you can see how far I have recessed the radios into the dash everything lines up perfectly. After installation, all the exposures were within .020” of each other.

Installing the nose lift

I decided to remove the Wright nose lift and replace it with a new Wilhelmson EZNose lift. I find the EZNoselift to be more repairable, smaller, lighter with better features (automatic extension).

The only major issue with the installation is the Wright nose lift uses a -5 bolt and the EZnoselift uses a -4 bolt.

The easy solution was to machine a couple of reducer bushing.

Air flow inlet

When I received the rebuilt Bendix throttle bottle from Airflow Performance (AFP) I also order an air filter and the flow guide to attach the filter to the fuel servo.

he strange thing is the flow guide has a 3.25” flange and the K&N filter they sell requires a 3.5” flange. I ask AFP what I should do and they really didn’t have an answer for the issue. I was told to just cut a piece of PVC pipe and use the ring as a spacer to fill the gap… Yikes! do people real do that sort of thing on their planes?

Amazingly, I happened to have some 1” AL stock of the right size and decided to machine my own flow guide.

IMG_0710-2019-12-23-20-09.jpg

That 1” AL is really thick and difficult to work with. After cutting the block off I needed to remove the center to make a hole.

Next is is spending a bit of fun time on the lathe.

IMG_0713-2019-12-23-20-09.jpg

Four hours later, I had a new flange with the 3.5” flange I wanted which was basically free. Now I’ll return the $135 air inlet back to AFP.

Fuel Injection Installation

Today I started removing at the Ellison throttle body fuel system with the primer and facet pumps. I also sent the entire Bendix system to Airflow performance for overhaul.

New panel

I thought I would show what the new panel would look like.

Making the panel out of .090” 6061T-6 aluminum will actually be fairly easy to do. I am looking forward to that part of the project. IMG_0610-2019-12-1-20-04.jpg

Wiring removal

Today I started on removing the wiring from the plane. I wanted to preserved some of the original wiring (starter, ignition, etc).

IMG_0562-2019-11-25-19-57.jpg

A nice looking instrument panel. I wold the entire panel to Spencer for a cozy 3 project he is working on.

IMG_0561-2019-11-25-19-57.jpg

I decided that I wanted to wire the plane differently and with the installation of the Dynon SkyView system, the harnesses will be completely different. I felt it was better to replace everything.

Successful Move

Today the Cozy was brought home from the airport.

A very dear friend, Roger was instrumental in helping me remove the wings and he bought over his large trailer to transport the plane to my shop.

Tomorrow I’ll begin disassembling the plane’s electrical system which will be a little challenging because I want to preserve some parts of the system such as the ignition and charging systems, while removing most of the rest of the dash and electrical wires and instrumentation.

Disassembly of the Cozy 4

I am finally ready to get started. For the last few weeks I have been working on the panel design and wiring schematics.

It is time move the plane home. It took a few hours to prepare for wing removal and transportation. Tomorrow Rodger will be stopping by with his trailer to move it to my workshop. Yay!

The Journey has begun

Back in August I purchased a beautiful Cozy 4 from Ed Richards in Tampa. I have know Ed for years, have flown in his plane and have always been impressed with his attention to detail building this bird.

IMG_8433-2018-11-23-10-39.jpg

The plane had all the physical modifications I was interested in, so I decided to buy it instead of completing the Cozy 3 I was working on.

IMG_7249-2018-11-23-10-39.jpg

I know it would take me many years to complete the cozy3 and quite frankly, I am tired of building. It was sold to Spencer in October 2019.

IMG_9758-2018-11-23-10-39.jpg

As much as I am impressed with the Cozy4, the one area I am very particular about is wiring and wiring documentation which incidentally is one area I am very passionate about. Wiring is the KEY to a good flying trouble free plane. After getting further into the ownership of Ed’s plane, I decided I needed to upgrade the wiring and while at it upgrade the panel to fully understand and be able to repair the electrical system and to improve the flight experience.

I enjoy using the Grand Rapids Technology system in my LongEZ,

IMG_7192-2018-11-23-10-39.jpg My current LongEZ, GRT installation.

BUT, the technology is dated and this equipment is a major PITA to install. It is very typical of most avionics wiring.

For the Cozy I decided to go to the what I consider a higher level of design and simplicity and install a Dynon avionics package in the plane which will simplify the installation, reduce the wiring requirement, give me better customer support, and provide improved functionality over the GRT system.

This is the current panel installed in the cozy. Its a mix of older (some very old), equipment which while completely functional and state of the art 20 years ago, is not up to what I want in a plane at this point in time where the technology has vastly improved over the years.

IMG_6474-2018-11-23-10-39.jpg

This is the panel I intend to create for the Cozy, It looks simpler and will have vastly improved functionality over the original equipment in the plane.

Beyond the wiring I will be installing a fire suppression system, fuel injection, a new heat system, and a host of other things.

This will be my LAST plane project. After completing this upgrade I am done working on any more planes. Period.

I’ll be heavily documenting all the work that is done on this plane. Mainly the documentation will help me remember what the hell I have done and help others who follow building their planes. I hope it will be of help to the reader.
