Worked on drilling out main spar and doubler of VS. Also decided to drill out lightening holes. Learned a couple of new things about the drill press including how to adjust the travel (adjustment screws on the my left). Holes themselves weigh 2.4 oz. I suppose the particles weighed enough to figure 2.8 oz for the total saved. 2.8 oz x 15 ft = 2.6 ft lbs. Every little bit ads up I suppose.
