Warped Fins
I am building a Big Red Max and one of the fins has a bad warp in it. It is cupped along the long axis.
Has anyone ever had this problem, and if so, how did you go about fixing it? Thanks! |

Put it under a couple of heavy books for a few days. Lying flat, of course. If that fails, try spraying it down and repeating the process.

When spraying wood to flatten it I thought I remember hearing ammonia water works well.

Probably because it smells so bad that you don't want to lift the board until it dissipates.

Heh, while that may be true I believe it had to do with the ammonia softening up the wood fibers.
