This little Harbor Freight 1/4" router is one of my favorite tools. I have used it on aluminum, plywood, hardwood, Formica, and Filon. I have a big Craftsman router, but 90% of the time I use this little one. In this photo I am routing out the opening for the driver's side window. Note: the blue prepainted aluminum is covered with a protective plastic coating. It is really bright and shiny underneath. Yes, I know I have been saying red aluminum skin. The wife won out on this, so I went with blue instead. Next one will definitely be red.

Unfortunately, using a router on aluminum creates an unbelievable mess. There were aluminum shavings everywhere.

The window and door will be installed next.
Gold5one...my airplane is the original Sonex. I'm 60 years old and have been flying since I was 16. The Sonex is without a doubt the most fun to fly airplane I have ever flown. The jet is cool, but expensive.
