Bulkhead 704

February 9th and 16th, 16h

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.

Firewall

January 26th, Feb 2nd 15h

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.

Finishing the wings

January 19th, 8.5h

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
