Building a New Ruuder


Thanks for sharing the detailed info on the rudder rebuild. Very interesting!

2 questions;
1) as it looks like you had just 1 chance to get the rudder post lined up just right (with foam that dense I canít imagine how you could re-do the work once the first pouring of the foam hardened) how did you hold the post and shell in place to eliminate any movement, and how did you make measurements to ensure they were lined up perfectly?

2) how did you keep the walls of the shell from losing their shape as the foam expanded - were the walls of the shell so thick that when the foam expanded it only expanded upward toward the opening without pushing hard enough to deform the foil shape?
