In the process of replacing the steering cables on my Bayfield 29 I discovered that the eyebolts used for tensioning the cables seem to be corroded to the quadrant. I can back off the nuts but the eyebolts are completely seized. Any idea how to "unseize" them? Do I have to remove the quadrant? If so do I have to drop the rudder to do that? It looks to me like the quadrant is in two halves and I'm cautiously hoping I won't have to drop the rudder. Any advice?
