Re: [Cal_Boats] glassing a rudder?

Hi Reggie, I would not trust 1 layer to protect the rudder. 8oz is pretty thin. I would gauge the thickness of what was original and go from there. I would guess 3 or 4 layers minimum. It is just as easy to do 4 as it is 1. Every layer after is a little smaller than the previous one. Makes fairing easier. Best to do them all at the same time for best bond/strength.

Reg, I also thought that a single layer would be too thin. However, I have bought a couple rudders from Foss Foam (CA) over the years, and the skin on them was indeed very thin. Daniel, I am not sure those rudders have enough skin thickness to do the beveling one would want to do to the shrinking size layering. My conclusion is a big question mark. Dunno.
