Marked up CS Spar for spar cap troughs and FWD taper. Puzzled mightily why the top spar cap seems to get thicker as you go outboard, but finally notice it is not flat FWD/AFT, so actually tapers outboard. Most confusing. Will actually cut the bottom trough first because it looks easier, and the top will sit flat on the bench.
Will now pay the price of substituting H45 PVC for the plans 2lb urethane. I will not easily use the plans sanding block, but have decided to use the Drew Chaplin invented router box I last used to smooth the foam surrounding the NACA on the fuselage bottom.
Cleaned up the required templates with a file.
Had a bit of spare time, so cleaned up the CS1/4/5/8 micro joins with the router and actually started cutting the bottom trough.
Marking, marking. Not the usual workshop clobber. New Island workstation in the background...
