I picked up the replacement rear wing spar last weekend, and today I got everything redone and swapped back onto the right wing. It's amazing how much easier it is the second time around, mostly because I didn't have to spend hours scratching my head trying to figure something out on the plans (it helps having a completed wing to reference too). Instead of going step by step through the instructions, this time around I took a number of liberties in the order I did things based on some lessons learned while finishing up the left wing.
First step was getting all of the holes final sized and match drilled where appropriate, then preparing everything for primer. Priming only took a few minutes since it was 90 degrees outside and the primer dried pretty much instantaneously. I went ahead and dimpled all of the rear spar flanges before I assembled anything. Far easier than doing it when it's on the wing stand.
