Tonight the wife and I ripped the $100 sheet of 9mm Hydrotek into 5 1/4" sections to be used in the building of the I-beam spars. We also ripped the $83 chunk of Douglas fir into roughly 1"x 5/16" caps for the spars. I will set these aside until I get done building the ribs.

The table saw blade took a beating cutting up the Douglas fir....not as easy as cutting Sitka spruce
