FUSELAGE CONSTRUCTION - Page 19.

August 15, 2003:  I worked on the main bulkhead that came with the wing kit as part of a matched set with the wing spars.   Part of the work here was to modify the two machined aluminum brackets that hold the control sticks.  When I had them assembled, I calibrated the sticks to be parallel.  I have the control assembly just sitting on top of the bulkhead for this photo.

Here you see both bulkheads and the associated parts that I worked with today installing platenuts and opening holes for fuel lines and electrical connections.  I also made the tubular spacers that keep the middle section bolted at the proper clearance.   I have some oak that I have to cut to the proper dimensions to represent the wing spars when I finish bolting all this together for further assembly later with the skins and longerons.

August 18, 2003:  I finished making hardwood spacers to represent the wing spars, then fitted the main wing attach bolts to the two F904 bulkheads shown in the photo above.  After marking all the bolts to be able to return them to the same places, the bulkheads were disassembled and set aside.  All the non-anodized parts will be primed before assembly.  Today also saw the beginning of work on the F705, which is behind the seats and also attaches to the rear spar of the wing to set the wing incidence when the wing is finally attached.  The photo below shows my progress as of quitting time tonight.

That aluminum bar stock running across the bottom of the assembly had no holes in it when I started on this section.  (The wide-angle setting of the camera zoom lens makes the straight bar and table edge look bowed.)  I also fabricated two spacers and drilled and trimmed the F605C doublers that form the attach points for the wing rear spar at the extreme left and right sides of the assembly shown above.  Those eight gray painted parts in the middle of the picture are the steel seat belt attach brackets.  They will be bolted to the F705B doubler you see in this assembly.  Total time of aircraft construction is 597.6 hours, with an additional 58.7 hours of other prep work including unpacking, inventory of received parts, and building all the work tables, jigs, and saw horses.  Total time on the RV-9A project = 656.3 hours.

August 19, 2003:  I finshed the work on the F705 bulkhead group and moved on to the F706 bulkhead, which is at the rear of the baggage area.  This also includes the area where the elevator push rod connects to a belcrank and another push rod that connects directly to the elevators.  All these bulkheads have holes and bushings for the rudder cables to pass through on the way to the tail itself.  The 5/8" bushing below is the one that allows the elevator trim cable to pass from the baggage area sub-floor into the tail cone area.

Here is the full view of the F706 baggage bulkhead.  The closeup above is at the bottom center of the photo below.
