I stumbled onto this webpage with a simple description of how to make a foil with a router- no jig required. And it made a great deal of sense to me.
And then great things started to happen.
Brief summary- After consulting the plans to figure out the shape of the foil, we made a list of offsets to mark on the blanks. We basically broke down the centerboard cross section into measured increments, a bit like a topographic map.
After we had all the lines marked, we used the router to cut out each section.
Like this:
Then I used my block plane to smooth it all out.
I'm quite pleased with the cross section- it's starting to look like a foil! I'm finally heading in the right direction.
I'm a long ways away from being finished with it, but I foresee great things in this centerboard's future. Plus, it's the last of my 3/4" Okoume, so I had better get this one right.
Sweet move, learned myself a new trick.

Hey Arthur! Hope it comes in handy. :) Did you get your plans yet?
DeleteNo not yet they said in about two more days. I did take your advice and they where kind enough to email me the PDF. So thank you for the suggestion.

You're most welcome! Hope the build manual tides you over until your plans arrive. :) I had mine printed and I've been packing it around with me religiously. It's starting to look pretty battleworn, and I haven't even reached the epoxy phase yet!
DeleteVery nice start. This is the method I used when shaping SCAMP #1's CB. It was laminated from 2x2" cedar.

Your photos are amazing, Simeon. That is a great looking board, too.
DeleteYou center board is coming along nicely. I had made some wings for RC airplanes. They used the same method you did for figuring each cord. On my center board I marked about i/4 out for the front of the board and rounded to that point. A longer taper on the back. Just did it by eye ball. Turned out fine. Use the layers of ply as a guide. I pined the two boards together using wood dowels for alignment. This worked fine. I left them in for glue up. Pete Hull 52
ReplyDeleteThanks for your suggestions, Pete! I like the idea of using dowels for alignment. It's great working with ply, isn't it? I love having the layers as a guide.
DeleteHappy building!
