Took a break on the rear spar and moved on to the front spar. This proved a bit more challenging as the HS0003 spar doublers are a later addition to the plans as they came about from a recent SB. As such, the plans were a little disjointed, but I figured out how to properly match drill all the holes for the doublers and front spar. I'm realizing how important it is to take your time and think things through.
