We prepped and riveted bulkhead 705. All went well, except for one bracket that did not align well. So, I just ordered a new one.
We finished riveting bulkhead 704. We riveted all the brackets and the side sections. Then we looked up and gathered all the hardware. Bulkhead 704 is done for the time being.
Then I did a little preview into bulkhead 705, so I gathered all the parts.
Next we started working on the bulkhead. First drilling holes for the bushings. Then drilling the center sections to the sides. Afterwards, fabricating the control brackets and drilling them.
Next weekend, we primed the control brackets and fitted the control sticks. Then we attached the platenuts. Afterwards we worked on the cover ribs. The center bushing holes ended up a bit larger, 9/16 instead of 7/16, so I am most likely redoing those ribs after checking with Vans.
We started working on the fuselage. The first part is the firewall. Which is made from stainless steel. It had very sharp edges, so we needed to be very careful in smoothing the edges. Then we prepped the firewall and all the stiffeners that attaches to it, matched drilled, deburred, dimpled and counter sink as needed.
The next weekend, we primed and riveted all the parts, except for the aux fuel pump doubler. We don’t need this part for fuel injected engines. Also, the firewall recess was not riveted for the time being, so that we have access.
Final touch-ups on the wings.
We drilled the inboard bracket for the flap hinge, drove the hinge through the hole and bent the flap hinge. This finalized the flap installation.
We drilled the wing tips. We were thinking of going all the way to installing all the platenuts, but after consulting with Vans, they suggested waiting on the platenuts until attaching the wings to the fuselage. This way, I will be able to get a better alignment of the wing tips with the neutral position.
Then we installed all the access plates. The wings are complete for the time being
We finished installing the lights into the wing tips. We had to make some small adjustment to the wing tips for a smooth insertion of the lights. Then we riveted the plate nuts, and attached the lights.
Afterwards, we moved to the lens. We did a rough cut of the lens, then we set each half on top of its wing tip, and traced a contour to follow. Based on the contour, we cut he lens using snips, then we sanded it to get a nice finish.
Afterward, to attach the lens to the wing tip, we decided to go with 2 plate nuts per lens. we match drilled the lens to the wing tip, then we drilled the rest of the holes for the plate nuts and riveted it. Finally we attached the lens to the wing tip. The result looks great.
.
After further Analysis of the alignment of the flap hinge attached to the skin, we realized that we can just adjust the teeth of the hinge. The adjustments were very small, then we tested attaching the right flap. We went through few trials, until we got to the desired results, the pin can easily flow between the 2 parts of the hinge. The flap was attached and the motion is pretty smooth. The wing looks complete, only couple items remaining.
Today, we finished the wing skin riveting.
First, we fixed the little dent in the left leading edge following Vans instructions by forming a piece of wood to fill the leading edge from the inside and using a mallet, carefully fixing the dent. Then, we finished the last panels of riveting in the left wing.
Afterward, we moved on to riveting the plate nuts for all the access panels.
