Trimmed, fitted, match drilled HS0001 Spar Doublers, HS702 fwd spars. Match drilled, trimmed and bent HS710&714 reinforcing angles per print. Some of these holes get match drilled through existing holes in the 710&714 so they are easy to get perpendicular, but some of them have pilot holes on the thin side that you drill though into the thicker material. Seems to me that it would be pretty easy to drill crooked into the 710 & 714 on those, so I used a drill guide to keep everything plumb. Tripped a breaker by had a space heater & shop vac running, then when my compressor kicked on it tripped the breaker. No big deal, but for some reason when I reset it, the compressor wouldn't come back on. I think there was something going on with the start capacitor. I took it apart and re-twisted the wire nuts connecting to make sure they were tight it and it fired right up after that. It got me going again, but I pulled the plug from the wall when I shut down tonight, until I can figure out what's going on with it. This is a little frustrating. It's a Kobalt from Lowes, and only about a year old.
