Task: Tank bracket and trimming canopy frame
Tonight we accomplished many tasks We drilled the holes for
the fuel vent lines in the fuselage. They were punched already
so I just opened them up to 7/16. We also worked on the fuel
tank bracket doubler angles and then back to the canopy frame.
7/16 hole is where the fuel tank vent line exits the fuselage.
The hole on the right is where the vent is located. Rather than
use a cut off AN fitting for a vent, we are going to go with
new vents from JD
Air. They look really nice!
Next we clecod the tank support brackets and shims onto the
fuselage and opened up the upper and lower holes for an AN3
task of the evening was to continue work on the canopy frame.
The height of the frame is supposed to be 17 7/8", however
we are shortening ours both lengthwise and in hight to accommidate
the Sikaflex glue. Due to headroom restrictions, I don't want
to shorten it by too much. So we decided to make the dimension
17.71. This meant trimming away some of the rear portion of
the frame so it could next in the F-631C.
Once the aft edges were trimmed we remounted the frame in position
on the fuselage. It fit well and to the correct height.
Before we could match-drill the holes through the skin into
the canopy frame, I needed to fabricate 2 shims to takeup the
extra space outside of the F-631C and inside of the skin.
With the shim in place, the skin lays perfectly flat over the
F-631C mounting bracket.
