[frers-list]Rudder bearings

[Arthur Kelley]

Mark,

See the FAQ section of the web site for detailed info.

Hull #55 had a rudder post of 2.490", and a housing size of 3.025 (ID of 
tube bushing fit into).  The dimensions of the tube as manufactured depends 
on how you are fitting the tube (press fit or slip) and the material.  I had 
the bushing machined to an OD of 3.033" and an ID of 2.511" for Vesconite 
HiLube "press fit" by chilling the bushing in dry ice, and slipping into the 
housing tube.  Once it warmed, the bushing was firmly embedded.  Vesconite 
has a calculator for this on their web site.  This is a South African 
company specializing in bearings/bushings for ships, but custom machining 
and shipping was cheaper than a US product that the manufacturer (Tides 
Marine) was unconvinced would serve the purpose.  Others have gotten the 
work done domestically.

MEASURE YOURS FIRST!!!
