Elevator Push Rod

I removed the push Rod and marked it for drilling. I had to go back to the C03 drawing for the location of the holes. I marked the holes in C03-05 half and drilled them using my drill press. I setup a couple of 1×1 angles to assist with the alignment of the tube. After drilling the -05 half I inserted an aligned the -06 half. I then drilled half of one hole in the -06 half of the push rod.

The next thing I did was to reinstall the push Rod and use a cleco to through the single hole through both parts to verify the correct alignment. It turned out that I was off by about 1/8″. I removed the push rood and drilled a second hol in the -06 half. This time I was able to get full movement of the elevator. The control triangle was still very tight to the rivets on the spar tunnel.I decided that I could flatten some of these rivets a bit using my bucking block inside the tunnel and a hammer on the end of the rivets that were protruding.

Elevator Push Rod

Today I worked on the installation of the elevator push rod. I started by opening up the hole in the in the rear spar carry through channel. This was to allow more adjustability in the push rod. I was finding the with the stick full aft the push rod bellcrank would contact the channel. I opened the bottom of hole by about 3/16″.

Next I installed the push rode and tried to find a position that left a bit of clearance at each end of the stick movement fore and aft. I applied masking tape to the push rod and marked a position that was 3/4″from the overlapping point of the two parts of the push rod. Next I marked an alignment line on the top on bottom. This will allow me to line up the two parts outside of the fuselage when I drill the two holes through them to connect the two pieces.

I then found the remaining channels for the fuselage so that I could mark them for the push rod hole. When I got out the channels I discovered that I had previously put the holes in them.

I clecoed the channels in place in the fuselage and reinstalled the elevator push rod. The hole in the rear most channels seemed okay but the hole in the front channel appears to be too high. I think I will see if I can make a new front channel with the hole about 3/16” lower.

The next step will be to remove the push rod and drill the three holes required for the AN3 bolts to secure the to pieces together.


I worked a bit on the controls today. First I moved one washer on each end of the link between the control triangle and the intermediate connection from the outside to the inside. This reduces the possibility of the link rubbing at each end and enters it a bit better in the hole under the rear of the seat.

I also started the installation of one of the rudder cable by installing it through the fairleads on the left side of the fuselage both front and rear.

Windshield Finishing

Today I have started to work on finishing the windshield installation. Before starting I marked the bow strap where I wanted to extend it to better fit with the canopy. I took a number of photos to explore this area. After opening the canopy I put a ratchet strap on the windshield and started by removing the fasteners between the windshield and windshield bow. Next I removed the clecos.

With all the fasteners and clecos removed I was able to carefully remove the windshield and windshield bow strap. Once the windshield was removed I removed the protective covering from the forward half of the glare shield and then cleaned up the aluminum with some acetone to remove the glue and some scotchbrite for a few minor scratches.

I discovered a couple of rivets that I had left out. One on each side where the two halves of my custom glare shield join. At first I thought I would see if I could get some stainless steel washers for the underside of these rivets. I could not find any at my local Home Depot that were the correct size so I decided to make some backing plates out of aluminum. These were made from some 1/16″ 6061-T6 material that I had and were cut to 3/4″ x 3/4″ square with a #30 hole in the center. I then used a couple of CCP-44 rivets to finish fastening the glareshield in place.

I also discovered that the stainless steel fasteners I had ordered for the glare shield were too short. I’ll need to order some new fasteners.

Control Stick/Triangle Installation

I need to make some changes/repairs in the fuselage. I discovered that I must have missed note in View H-H on sheet F01. Today I’m going to drill out the rivets and install them from the opposite side so that the control triangle can be installed.

Canopy – Tooling

Today I worked on some tooling to help with the final triming of the canopy. I found that the toughest part of fitting the canopy was pulling  it into position along the fuselage sides. So, I made up some pieces of MDF that I could clamp to the sides of the fuselage using ratchet straps. The MDF ends up flush with the upper longerons and provides a surface that I can clamp to. I plan to clamp some AL angles to the MDF to hold the canopy in place for the final fitting before I start drilling holes. I’m also hoping that I can drill the canopy while it is clamped in place. I know a lot of builders use a ratchet strap to pull the canopy down into place but I find this distorts the canopy so I really want to let it side in place and just pull in the portion that aligns with the upper longerons.

Tail Wheel Installation

I continued to work on installing the tail wheel. I reinstalled the tail wheel mount and proceeded to install and torque the fasteners. I found that I needed an additional washer on each fastener to get the correct grip length.
