The Sept/Oct issue of Good Old Boat Magazine had an article on page 43 to 45 complete with picture and instructions on how to make a tool to remove an old cutlass bearing without removing the strut. (The skeg which not all boats have, them but my 82 Hunter 30 does, is a fixed fin that is in front of the rudder. Usually the forward part of the rudder is attached to the skeg.) Anyway if you can't get access to the magazine you can e-mail me with your address and I'll send you an image of the article. You might consider getting a subscription, Good Old Boat is one of the best sailing mags around....
