I'm paddlin.
Appreciate the votes of confidence guys.....
I've started the ribbing.
Now I had trouble trying to form the .03 x .06 styrene along the widest part. So I had to think a bit outside the box. When forming sheet metal, to shorten the length of one side of a sheet, they Crimp it. When a solid is Piched, it lengthens. So if you strike one side of a solid with a cold chisel it will try and stretch. So having said that, I used a pair of scissors to Pinch one side of the styrene, this caused it to stretch and therefor create a curve. It's just a touch of a cut, not thru. The smaller the radius, the closer you pinch, on the long curve it was just a couple of pinches much farther apart.
Takes about 5-8 minutes each. I figure in a month I should have all the ribs in!!!!!
*Oh, I made a square out of thin styrene sheet to mark the rib lines. Thin sheet so it would bend on the curve of the side.
