Rudder Frame Construction

Rob and Janet Sutton

Hello Bud,

Say we are finalizing the drawing for the rudder frame for the rudder of our W42. I am basing it on the drawings in the construction manual and a copy of the rudder cross-section drawing.

Q: Do you recall the thickness of the SS plate used? While the drawing does not say, the scale says it is about 1/2" thick. Does that sound right?

Q: Also, we are considering using 2" solid shaft material instead of the schedule 80 SS pipe for the rudder post/pintle. The idea is with this diameter we can easily fit a 2" cutlass bearing in the gudgeon shoe. Do you see any problems with this?

The rudder plate was mild steel, not stainless. I believe it was 1/2".
Since the original rudder post was 2-3/8" OD, the fiberglass tube bonded in the hull for the upper end is 2-3/8" ID. Also, the hole in the rudder quadrant is also 2-3/8" ID. If you change to 2" OD, then you will have to bush both of these fittings. Easier to use 2-3/8" OD pipe, and get a 2-3/8" ID cutlass bearing.
