rudder rope stopper
Posted: Sat Jul 22, 2006 10:48 am
While fiddling around in the gravel that is my boat yard, I either kicked this piece to some invisible place or I have misplaced it.
This stopper is a stainless steel tube that looks a bit like a T junction with the leg sawed off, or maybe it is just a tube with a hole drilled in it. It is in the rudder and the stopper knot at the end of the rope is inside it. It serves as a short bar transversing the thickness of the rudder to bear and pull the weight of the rudder when raising and lowering the kick-up, thru-the hull rudder assembly. The pictures on the other site were helpful for everything else about reinstalling the rudder, but it doesn't show this little mechanism.
It is 7/8ths inch tubing with a .0625 or so wall thickness, stainless steel. It is only 1 5/8ths inches long, but the only source of this tube in town requires that I by a 20 foot pipe for over 60 bucks.
Does any one have any ideas for replacement?
a. I could use the available 1 inch pipe and just increase the size of the hole. However, the hole is designed so that the hole at the edge is slightly smaller than the diameter of the rest of the hole in the interior so it doesn't drop out when it is not under pressure--I don't think I can replicate this nice detail in the wood and might loose it under sail. Could I even drill through that for the hole in the middle of it using a conventional drill.
b. I could use another type of piping. But what? Galvanized pipe (gas piping?) would eventually rust, copper is probably too soft to bear the weight of the rudder, and even electrical conduit looks weak.
I'm going out one more time to look for it, now that it has rained, it should stand out on the gravel dust. But if I don't find it, I'll have to do something.
Sure could use some advice.
