Bronze on Bronze


Recommended Posts

Dropped the rudder out today and found that it's supported by a bronze ring that screws onto the top of the rudder stock.  As the rudder stock turns this ring turns with it.

This then sits on top of a another chunk of bronze which is attached to the cockpit floor.

So as the rudder is turned, the bronze ring slides on the bronze base.

There is no way to lubricate this unless the rudder is removed.  I always understood that metal on metal is bad - is bronze on bronze OK?  Should there be a thin washer which has just eroded?

It's not broken and I have never had any problems with the rudder, it's always been really smooth/easy to turn, so I feel like this is a case of if it's not broken don't fix it... planning on spraying it with some PTFE and a dab of grease and just putting it back together...

Thoughts?
