[Public-List] Replacing a mast step

[Don Campbell via Public-List]

Just an addition that many many not know or thought about, but the original 
wiring for lights on the mast used the mast as the electrical conductor to 
return the current to the panel. There was a short white wire affixed with a 
machine screw to the base of the mast to reconnect the mast to a wire that 
was the return to the panel for the DC current. If that system still exists 
on a boat, one does not want to mix metals to increase galvanic action 
between them. In any event, that wiring system ought to be replaced with 
wire rather than the mast as the conduit.

Subject: [Public-List] Replacing a mast step

I am replacing my mast step (the casting had cracked by one of the bolt 
slots). I am having the new one made from plate metal, with a piece or 
pieces welded on top that are curved to fit into the bottom of the mast.

The metal shop was thinking stainless steel for strength and corrosion 
resistance.  Would that be best, or should I stick with aluminum to prevent 
corrosion issues between it and the aluminum mast and aluminum plate bedded 
in the deck?

Thanks,
Mike
