the W-726 spacers to the W-731 tie-down bracket.
Mounted the bracket assemblies to the main

Started the rear spars by edge deburring The
W-707A/D/E/F/G spars and reinforcement brackets.
The RV-7 requires a slightly smaller W-707D
due to fuselage mounting clearance. I marked the dimensions
per DWG 38 and cut on a band saw.
I clamped W-707F into position on the end of
the W-707G spar using cleco clamps.
Then match drilled all holes to #30.
Measured 50.75" from the outboard end
of the spar for horizontal placement of W-707E.
Then match drilled...
Next I used my unibit to open up the aileron

really well. Its an odd shaped opening..
we clecod the W-707D and W-707G onto the W-707A rear spar
and match drilled.
We repeated for the right spar and then deburred
all holes. Ready for priming!
