When in doubt... build hell-for-stout!
I made some curved fins and documented the technique on this thread and wanted to document it on the "Techniques" sub-forum since the end product came out well.
A 5-ply construction was used: (3) pieces of 11 mil printer paper and (2) pieces of 1/16 balsa.
For curved fins I made a form out of 3" pvc pipe. For flat fins, simply use some scrap plywood as the form.
Gorilla Wood Glue was used, with a little water added.
After allowing the part to dry in the form for 72 hours the plywood was removed and then clamped just to the o.d. of the form, to allow another 24 hours of drying.
