What is Lumpy's rudder made out of????
Sanding had very litle effect on it.
Had to use a grinder!
It looks like that rock hard, gray epoxy!
Once I had flattend the port side, I found that it still came no where near to having the ruddered centered on the screw. (Prop for you non naval types) Found out the the rudder post hole is on an angle.
Pressed the rudder post tube out of the hull and filled the hole with a dowl rod and wood filler.
