Shaping The Keel Fin
Got home from work today and had some time to work on the keel fin core. After finishing making the cuts, I spray painted the whole thing dark green. By doing this, it will be easy to see the depth I need to go to as I chisel and sand. By using a chisel and mallet, I'm able to get rid of the wood and bring it down toward the right shape. Then I use the sander to continue shaping the blank. Once I get the foil shape roughed, I'll make a template and use filler to fine tune things. It's fun and I'm feeling quite craftsman-like as I'm using the mallet and chisel to carve this foil shape. Just hoping the finished core looks craftsman like!
On my way home, I stopped by Fiberglass Supply (that place is like a candy store..without the tooth decay!) and picked up the glass I'll need for the lamination. I'm using 12 oz bi-axial e glass and 10.3 oz unidirectional e glass. Probably around 6 layers of each will give me the strength I need and will give the foil a skin thickness of 1/8 inch which will give me the right shape.
