[C38] Rudder packing challenges

[Don Strong]

Dear C38 Colleagues.
         Update my rudder packing efforts. As we discussed before and as 
Russ has observed today, with wheel steering the rudder tube is cut open in 
the middle for attaching the steering quadrant.  The bronze stuffing box is 
on the top of the bottom part of tube that the rudder shaft passes through, 
and the quadrant rides about 1/2 inch above the stuffing box. I do not 
think that a gaitor will fit on a tube with steering quadrants; too little 
room for attachment.  It is a huge job to remove the steering quadrant, but 
you must do so before replacing the packing/ stuffing.
         I believe that I used 1/2 inch teflon coated synthetic stuffing 
from West Marine (This kind lasts longer and cuts more accurately than the 
natural old kind)  and was able to get three courses of it into the empty 
box. I hammered the stuffing on a wooden block to flatten it before 
insertion, this facilitates sliding the stuffing into the stuffing box. The 
distortion caused by hammering disappears when you tighten the squeeze 
bolts on the box.
         However, my rudder shaft has lots and lots of play, and it needs 
shimming of at least 25 thousands of an inch on each side, as mesured in 
the cockpit at the tube top where the rudder attachment is fixed.
         This play (I hope it is the play) means that even brand new 
stuffing wears out in a few hours of use. So, my rudder shaft leaks as much 
through the box as ever after only a few hours of use, with new 
stuffing.  It may be that I need to replace the bottom bearing ( is it 
delrin?) on the rudder, but that will have to wait till haul out. Im going 
to try to shim the top of the tube in the next month or so and will inform 
you all of my results.

Still tryin' Don
