Accomplished a lot lately on the center section spar, forward bulkheads
and firewall. Here I drilled the bulkhead to aft wing spar bar.
Accomplished the seat back brackets which require a 4 degree bend. and
1/8" gap on the angle seen here in the pic.
Final drilled the seat belt brackets and aft bar doubler section.
Finished the spacers and angle with nut plates.
Finished these brackets with the nut plates and countersunk the spar
for final riveting.
Stopped by John Sanazarous house and we banged out the final firewall
