Cut Out First Plank

Tonight I cut out my first plank, the keel plank. The big thing here is that I wanted to be able to use my Rotozip with the aid of battens. It seemed to work pretty well. 

I may buy some styrofoam insulation to put under the sheets next time. That will give the ply a solid base and yet allow the bit to cut through easily. I'll spend a few dollars but the time saved will be huge. 

I plan to spile the rest of my planks. I don't trust that my set up will be close enough to use Clint's dimensions.
