Drilling and clecoeng the forward to skin.

Questions to Zenith about the skin.

My instrument panel is wide. I cannot wrap the skin around the cabin frame like on the drawings. I suspect the drawings is for the SD only.

Should the top skin be over the side skin or under, like the drawings says.

The most difficult - what to do with the 9 SS A5 rivets in the cabin frame? Should I remove them and set again through the top skin or I can leave the…

Started installing the forward top skin.
Continued making the left door frame.

Clecoed #30 the external gussets to the frame bars.

It is not clear what size, what type and what pitch of rivets to use in different parts of the window. I will ask Zenith.

The areas to question are: size A4 or A5, pitch 100 or 60, material soft, regular, SS, countersink, countersink angle (100 or 120)

Mabe the top and back bars for the right door frame.

Put more rivets in the front bottom fuselage.

Some A6 rivets are diffilult to set. The room is too tight to use a regular riveter. Depending on the rivet position I might not have enough strength to use a hand riveter.

I used clamps.…

The drawings shows the Forward Top Skim with an open hole for the cabin frame.

The actual part has a closed hole. With the firewall assembled and partially riveted to the fuselage it is not clear how to put the Forward Top Skin in place.

Zenith said - either try to push it through the gap between the firewall and the cabin frame or cut the skin and use 0.025 thick patch with A5 rivets pitch 40, like Super Duty has.…

In case you forgot to get flowers today there is still time to go out to the shop and make a 6061 T6 rose.

Attached the main landing gear. Have several questions. Asked Zenith.

1. The drawings and assembly manuals describe 2 styles of installing the main gear support - the vertical edge inward and the vertical edge outward. Does it matter from the structural point of view?

2. When the supports are installed the vertical edge out the trimming in the drawings makes sence. If it is installed the edge out - the trimming looks useless.

3. When installing the…

Assembled and balanced the main wheels. Slightly cut the edge of the dimpled washer to make it fit in the wheel.

Made a custom wrench to screw the stop nut in the nose wheel. The wrench should go through the hole in the wheel.…

Today I wrestled with getting my Horizontal stab top skin installed and LOST. I decided to step away tonight and regroup tomorrow. I’m going to try something tomorrow using some Velcro straps rather than the ratchet straps - going shopping tomorrow 🤞.

November 1, 2024

Installed the main wheels axles.

Zenith answered. The brake caliper should move freely. Filing the corner of the main spring.

October 28, 2024

Asking Zenith.

The brake caliper interferes with the main spring. As far as I understand the caliper should move freely. Actually it has a movement range of about 2mm.

Should I remove the corner of the main spring to allow the caliper to move the full range?…
