Completed through KAI 8-7. The key to progress is to just keep doing working on it - I try to work a little everyday.
The Numatx squeezer proves over and over that it's one of the most valuable tools in my shop. I prepped the rest of the HS parts, which is an annoying routine of removing blue plastic coating and deburring, which is my least favorite task of building. But, then I set and squeezed the spar doubler section of the forward spar, HS-1002 in just a few minutes with excellent, nearly identical shop heads - one of my favorite parts of building.
