This weekend the engine mount was reinstalled. It was realized that there are two steel angles that have not been drilled into place yet and need to.

The next steps of the controls will require pulling the fuselage out to mount the rudder hinge. Foul weather prevented this. The hinges were fabricated over the weekend.

The wiring diagram was started. The current plan is:

Dynon D180
Airgizmo / Garmin 496
Garmin GTX 327 Transponder
ICOM A210 Transceiver

I am using Visio to create a fully detailed diagram. The hope is that I can decide on color coding before hand and decide where additional connectors may be wanted to help with maintainability.

I recently moved. Packing a mostly finished airframe and a "used" workshop and then moving it across town is harder than you would think.

First the plane with the gear was about two inches wider than the trailer. This required removing one wheel. Next there is the organizational issue. The new garage is smaller and needs more organization. The plane needs to sit at a diagonal to fit. Once the engine is hung the door from the garage into the house will need to be removed to fit the plane.

Recent progress has included mounting the rudder pedals, brakes and nose steering. I also fabricated the rudder cable pulleys and some rudder mounting parts.

Here is the new workspace ( Requires Silverlight )

This picture illustrates that I placed the horizontal stabilizer mounts 10mm to far inside on both sides.

Two options exist in my mind for fixing this.

The first option is to create a custom mount from the fuselage side shaped to clear the flange of the stabilizer's mount. This would require a spacer and a much longer bolt. It also increases the chance of the mount cracking.

The second option is to open the stabilizer and move the mounts 10mm outside. This may require some work to the spar.

The controls are coming along nicely. The push rods and flaperon bellcranks are all connected. The flaperon mixer is also connected. The pushrods terminate where they will exit the fuselage.

I also figured out the wiring for the strobes and nav lights. They were pretty easy to deal with, but finding a suitable location for the control unit may be tricky.

I have been very bad about posting recently, but this should not be construed as the project not being worked on.

The whole workbench was partially redone and lowered about half a foot. This is so the plane can sit on its wheels on the ground.

The engine mount holes were drilled out to their final size and bolted on.

Work has started on the controls. All three bell cranks have been fabricated. The lower torque tube bearing was un-riveted to allow for the torque tube to be placed. I then found an unacceptable amount of ply, so a new lower bushing was fabricated to raise the torque tube up and remove the wiggle.

In addition I have fabricated the flaperon mixer bearings and started placing the "L" angle that supports them.

The front was buttoned up, the rear half of the engine mount was bolted on, the nose strut bolted on and the main gear were installed.

The plane is now rolling on its own.

Another monster six hour session finished the drilling for the slats. Only a few "gotchas" were hit.

First with the trailing edge skin be careful with the holes of the ribs. The last hole for each rib intersected the skin. This normally would not be a big deal but the ribs were already riveted ( per instructions ) to the bottom half of the main skin. In two cases ( outboard skins ) there was enough edge distance to drill out the rivets and use a strap duplicator to carry the hole onto the edge skin. With my inboard skins I had to make notches for the rivet heads.

All four slat pieces are drilled to final hole sizes and are ready to be deburred, primed and riveted.

First, to anyone who is about to order their wheels please, please, please pay attention. Just spend the extra $30 a wheel and buy the tubes. The Matco tubeless tires are a nightmare. Seriously, I would rather rivet my hand to a rabid raccoon than deal with those things again.

I probably spent 15 hours trying to get them to inflate.

Some of that time was spent trying to separate the wheels. They can be really tight a large amounts of brute force will need to be applied.

The valve stems are a pain to install. A local tire shop was kind and let me borrow a valve stem installer. After that you need to get the wheel somehow beaded with the tire AND then slip a crazy rubber band gasket on between the two halves of the wheel.

If you use the tubes then the valve just slips on through and the wheels self bead.


A huge amount of progress was made thanks to the help of another local 701 builder. Together we made substantial progress on the slats. The slats are pretty straight forward, except for a few gotchas that got me. The biggest has to do with the "L" angle that reinforces the slat skin near the supports.

Trying to be industrious I went and cut the "L", notched it, bent it to match and then located the holes and drilled them into one piece. I used one of the ribs to back drill into a mirrored rib and then duplicated the holes to all the ribs.

What I forgot to do was check that all the holes of the "L" went into the support. Luckily all the holes that made it into the support were within minimum edge distances, but one hole missed. So I had to drill a fifth hole into the "L" that then made it into the slat support.

In one monster eight hour session we got the "L" spar drilled into all four slat skins, all the ribs, supports and "L"s riveted together and on one piece the ribs drilled into the skin.

Quick status update:

The doors are on, the latches installed, the hinges hinging.

The main gear have had their notches made and are test fit. The front fork is ready for the wheel and tire. The landing gear and strut fittings have finally been bolted into place.

I did have some problems with the Matco wheels. Despite following the drawing, I can not separate the front wheel halves. There does not seem to be a retainer clip or anything like it.

The pilot side door is now installed along with the door handle and strike plate. The directions were lacking, and a backing plate needed to be made for the provided handle. I unscrewed the inside latch and measured the distance between the screw posts and the center piece.

After making the backing plates the handle was positioned using the backing plate and internal handle to determine where the strike plate needed to be.

The backing plate was then used as a template to drill into the fiberglass door and the handle as screwed together.

On the passenger side the door was thicker than the pilot side. This caused the screws not to reach through and thread into the door handle.

The door problem has been resolve. the solution was to trim 20mm off the top edges of the door sills. The major issue was matching the already existing holes into the fuselage frame. This was achieved by using a strap duplicator and the trimmed section of metal itself.

Once that was done, the hinges were drilled into the top of the door frame, then the hing was drilled into the door at some key spots to make sure the holes would clear.

After that one of the Dremels was revived with new motor brushes and the doors marked and trimmed.

Three hours were spent trimming the door sills and getting them drilled into place on the outside.

I decided to modify the trimming on the inside rear. Having the flap of aluminum that goes up next to the wing mount seemed wrong. It could not have provided any strength to the hinge mounting below, it made installation a pain in the ass, it would be hard to reach for riveting and it obscures an inspection point. Given that, I just lopped it off.

I spent about two hours trying to figure out how to trim the door sill ( 7F19-12 ).

The plans and directions are very lacking about the door sills. The forward half of the sill is easy to figure out, the outside rear is strange ( but figure-out-able ), but the rear inside is an enigma.

A quick search of the Matronics list and Google provided nothing.

Arlington 2008 Flyin:

It has been a while since the worklog has been updated, but progress has not totally stalled.

About six hours of work have gotten snuck into the project between life and Arlington.

The firewall has been fully clean, protected, reassembled and riveted together. In addition all the forward fuselage parts have been clecoed back together.

Some amount of time has been spent enlarging holes, finding missed holes, ect.

The next order of business are the doors. The directions are skimpier on these parts, so inferences need to be made. One issue is the existing holes that join the V-brace with the aluminum tubing along the top. The door sill sits on top of the tube, and it is impossible to back drill from the tube side. After talking to Zenith it is acceptable to 1) Use a strap duplicator to find the holes OR 2) Trim the door sill in such a way that these holes are bypassed.

Also I received clarification on the install order. 1) Doors 2) Skylight 3) Windshield.

I spent about two hours Sunday cleaning up most of the firewall and then applying corrosion protections. The landing fork section still needs to be drilled to size.

One major problem is the lack of A5 clecos. Make sure you have at least 100 of them.

I have finally started drilling out the holes in the firewall. These have been A3 size since the initial assembly just in case I needed to adjust something when working on the rest of the fuselage.

Today I noticed a small amount of corrosion around one of the clecos on the firewall, so it was decided to drill everything out, deburr, acid etch, scotchbrite and then zinc as soon as possible.

All of the holes ( save the engine mount bolt holes ) that lay in the horizontal plane are drilled.
