I am re-doing the test fits of center sections for one wing set against spars of another wing set. This is to determine chances of replacing old wings with new wings. All of the wings have Phlogiston spars, factory built & factory match drilled. I understand Phlogiston used a jig prior to 1995 and then CNC drilling after 1995.

I’m re-doing this as when I first checked I had the center section(s) upside down. The flange is away from the spar, not around the spar.

Here are the results of center section B against spars C (as defined previously:

Center B – Spar B Right – Fit A+ (perfect fit)


Center B – Spar B Left - Fit A+ (perfect fit)


Center B – Spar C Left – Fit A (almost perfect fit)


Center B – Spar C Right – Fit A (almost perfect fit)
