Notched the first HS404 - Centerpunched and then drilled holes at the edges of the notches. I used the drill press to drill the holes.

Notched the first HS404 - Rough cut the notches with the band saw. It his kind of hard to see in this picture, but I accidentally pushed it into the band saw blade on the left side after I cut the notch out. The blade went into the rib about 1/16th of an inch. The next one I build will be perfect! On the next one I will use the snips to cut out the notches instead of the band saw.

Notched the first HS404 - Cleand up the edges with the coarse and fine needle files. I wanted to leave the line on the left side, but the drill bit walked over a little when I drilled it, so I went ahead and took the line. Not an issue. One thing I have learned is to crank up the spring pressure a little more on my counter sink to get a little deeper indention so the drill bit does not walk. Use care not to deform the aluminum too much though.

Notched the first HS404 - Finished the first one and edge prepped about half of it. I also machine countersunk the holes in HS710 and HS714 along with dimpling the holes in the HS702s that are required by the plans.
