Evening regiment.......
1. what type of vessel?.......static or to be immersed...& what size planks?
2. PVA [white glue] is fine for static & non glassed/painted, polyurethane glue is totally impervious to moisture
3. bronze pins are appropriate... but depending on the model
These little bronze pins are approx. 0.8 mm diameter x 10 mm long & are barbed just like full sized bronze marine nails
So with the 10 mm length, these pins are suitable for use with say 2 to 5 mm thick planks......
I always pre drill a
0.5 mm diameter hole in the plank & frame

....the
diameter of the pre-drilled hole is arbitrary & dependent on the materials used.......
Good luck with your first POF build..... Derek
