Your profile shows you to be in Australia
. Bluestreak battens are manufactured there. I think you'd come out ahead buying
battens. There's a lot of engineering that goes into battens. You might have to make them several times to get the proper stiffness. We like Robichaud but shipping
is not cheap
Incidentally I would not recommend full battens, other than the top batten, for your Samson
. You'll lose shaping ability, add weight, add friction, and spend money
. The only boats we get excited about putting full battens on are those without a backstay.
