Brief Description:	steel work on center section
I started the steel work on the center section. I drilled and bolted the 4130 plates on the upper left-hand corner of the center section. This is pretty slow drilling, because the plates themselves are a quarter of an inch thick, plus there is an extra quarter-inch more aluminum in the center section compared to the wing spars.
