Pop riveted the rod ends to the internally/externally primed control rods.
The same process as the W-821's. You can detect some light corrosion on
these items so a vigorous priming session is now the early order of the
day!

As I'm trying to achieve
a batch priming session, I had not riveted the W-821 before so that I
could include these braces in the massive priming session to come!

Port flap followed the same markup/preparation as before.
Essential to measure/measure/measure and measure again to get the best result prior to drilling!

Hinge drilled out and a good result like the starboard flap fitting.
Clecoe stubs are nice and central along the hinge so thankfully, no minimum edge distance issues at this stage1
Phew! at last this is done. I've been worried about this for some time as it's a lot of drilling 'non prepunched holes' and also many builders have had edge distance issues. See next entry how things were in this regard........
I drilled through now predrilled skin and flap brace through the hinge. I started at the outboard flap for approx ten points and then did the same at the inboard end. This ensured the flap/hinge assembly was unlikely to move during the rest of the drill through.
This is the inboard hinge clamped and ready for the hinge to be drilled.
I used a 1/4" bolt to provide for the minimum specified clearance between aileron and flap.
Trailing edge alignment was achieved using a straight edge against the aileron (r/h/s) and extended along the flap and secured with the use of 1" mini clamps.
