Corroded lifeline stanchions

BallastBoy · #1 (**permalink**) 02-06-2002

3 of my 4 stainless stanchions have corroded and fused to the aluminum toerail including the nuts and bolts. I would like any advice on removing them and either reattaching them or replacing them. I''ve read that Tef-gel would prevent this from occuring. Thank you for responding.

Stainless steel and aluminum corrode because they are disimular metals. They must be kept separated as much as possible.
One way to accomplish this is to make a thin "gasket" of some non-conducting material to place between the two metals. I''ve used electrical tape on the back side of stainless fittings bolted to the boom/mast and it seems to do the job. Coat attaching bolts with an anti-seize compound when putting everything back together.

TRY DURALAC. PRACTICAL SAILOR SWEARS BY IT. I HAVE USED IT ALL OVER MY BOAT AND CAN REMOVE SCREWS THAT HAVE BEEN IN FOR 4 YEARS.

Thanks for the replies! Any thoughts on how to seperate them without doing major damage to the toe rail? I suppose I could drill out the bolts, but how about seperating the actual SS stanchion base from the aluminum toe rail? Could I cut or chisel them apart?
I would assume that replacing them would be a smart move for safety''s sake anyway.

Eric, you''re the second person to recommend that method, so will give it a try. Thanks again.

Don''t know about getting them apart but when you go to put the new ones on use lanacote(don''t be stingy with it either). Its another anti-corrosive that comes in a spray and a paste. Goop it all over everything and you''re good to go.
