Task: Roll Bar Attach
we continued work on the aileron trim module and started riveting
the roll bar supports. This involved riveting the F-705G brackets
to the bulkhead, the F-757 plates to the bulkhead, and running
the static line on the left side of the fuselage.
the trim bracket back together, we had to clamp the servo in
position and drill the 4 mounting holes. It is VERY tight in
that area and we ended up having to remove the elevator control
Next we clecod
and riveted the F-705G bracket in place. The two upper outboard
holes were impossible to rivet with my rivet-sets. So we decided
to open the holes for a #8 AN525 structural screw. I've seen
this done before and Van's has blessed it.
Next we installed
the F-757 plate. This plate ties the F-705 bulkhead to the upper
longerons and provides attachment for the canopy roll bar and
for the canopy to lock down into. This is a very thich and supportive
area of the fuselage.
Once the bulkhead was finished, we installed the static line.
I bought the tubing from McMaster-Carr. I had already drilled
the holes so it was just a matter of pulling the tubing through.
This past summer I had made these little static line retainers.
They are simply bent pieces of aluminum. We riveted them in
we installed the flap motor housing. It really helps brace the
The paint finish on the right F-757 didn't turn out very well
so I decided to strip it and repaint.
