[Public-List] Newbee Looking for help with rudder parts

[Glenn]

Michael, interesting the way your pintel and grudgeon are installed.  My boat was built in '68 and the pintel is actually an exposed part of the rudder shaft. So is 1" diameter.  

A word of caution, i observed a point of failure with the grudgeon halfs - the replacement 'bronze' screws and bolt that hold rhe two halfs of the grudgeon together corroded out and require regular replacement every few years.  I think the bronze used in screws these days is not the same quality as gun metal bronze screws of yesteryear.  Or the different materials cause electrolysis to eat away the less nobel screw. 

Also some years ago i replaced the original fine threaded machine screw that holds the shoe to the bottom of the rudder with a 3" bronze lag bolt.  The more aggressive threads bit into the bottom of the keel and have remained tight ever since.

This could be done with a beefier cross section where the thru bolts go to hold the split halves together.  I would like to see the pintle pin increased to 5/8" and/or the possibility of a replaceable bushing employed for the pintle.

I believe that all Alberg 30's are that way for the entire production run. She also has the fittings installed ass backwards. The pintle half of the "hinge" is on the keel and the gudgeon half on the rudder blade. Go figure. I wonder did someone at Whitby take a smoke break and when they came back installed the parts backwards?  All the other Alberg 30's I have observed had the pintle part on the rudder blade.

Peter McEvoy from San Francisco proved to us this past summer that these parts cast in bronze do not have to cost hundreds of dollars. Peter did a nice job supplying cast bronze rudder shoes for $100.00 plus shipping.
