The next thing that I did today was drill the right longeron beginning at the tailcone and working forward. I drilled up to the F704 bulkhead and then took a break for my compressor to cool off. I just have a small pancake compressor and it ran constantly while drilling the longeron since it isn't prepunched and since it is a relatively thick piece of angle. The next step was to dig out a ton of clamps and to securely clamp the forward end of the longeron to the side skin. Since the longeron is angled and twisted throughout this section, I had to make sure the skin was contoured and securely held to the longeron for drilling. Once everything was lined up and clamped I drilled the final section of the right longeron using the prepunched holes in the side skins as a guide.
