Hi folks,
This is a general question regarding the strength and rigidity of a wet layup. Would there be any mechanical difference in the finished item using fewer laminations of a heavier weight glass than more of a lighter weight, i.e. 3 @ 200g as opposed to 2 @ 300g.
Cheers, Marty

You can use balsa in an open mould. Lay up the outside part and let it cure. Bond in the balsa and stand a weight on it then let that cure. Finally lay up the outer skin. A core really does add a lot of stiffness so I think its worth your time to try it. I've used the 3mm PVC foam quite a lot and I was amazed at the difference it makes.
