bronze rub rail removal

Postby dcdunbar » Tue Sep 24, 2019 10:55 am

ANyone have an idea how to remove around 100' of bronze rub rail with screws on 5" centers on a '78 GB 42? I painted the boat about 7 years ago and the bronze has streaked down the side of the boat which has affected the finish. I'd like to replace with stainless but intimidated by trying to take out at lease 200 flat head corroded screws.

many thanks

Not to be a wise guy but take em out 1 at a time. Maybe an “old Fashioned” bit brace might help if they are hard to break loose. An electric drill or screwdriver will just strip the heads and make the job harder.

You need a screw extractor by "Armstrong..." Sorry, this looks you need to do it the old fashioned way, just get them out one by one. The suggestion above to use a bit brace is a good one. You can lean into the brace while cranking in reverse and the screw will come out probably faster than using an electric drill. Good luck!

You might find some of them breaking with just the head coming out and the body of the screw left in the rail. A bit brace is a big help. A corner bit brace is a bit easier to use sometimes.

Make sure that you REALLY want or need to do this, would be my only advice.
I have tackled trying to replace just a few screws on my 1973 and even that can be a challenge. Sheering off etc.
Are you certain the streaking on the hull is coming from the bronze?
My streaking is caused by the fact that the water seeps through the old teak decks into the plywood base and then finds it's way out underneath the rubrail and stains my nice white hull. I just clean it off!
Keep us posted! Alan.

What he says.

To me it seems like a lot of work and end up with what is in my opinion an inferior, less noble material.

Maybe easier to try to clean the streaks, if that is really the source of the problem which I have not seen before.

It’s probably coming from under the rub rail, due to leaks in the teak deck. As the sub deck deteriorates, it will ooze out “brown water” which is a tel tale sign of rot underneath. I seriously doubt if it is the bronze. Besides bad caulking in the decks, a major cause of teak deck leaks in this area are the stanchions. Pull and seal all the stanchion to deck joints with butyl tape.

Thanks for all the replies and sorry that I just got back to the post. I like the idea of the bit brace but really concerned that there isnt any head left on the screw and I would just end up stripping them anyway... It's a big job and not sure I want to tackle this unless the streaks are coming from the bronze. I have removed the teak decks and the only thing that I can see that would cause the streaking on the awlgrip is the bronze. Maybe there some weeping of bronze/resin from where the screw goes into the rubrail but I never see anything definitive.

I recently launched the boat back in water so it might be difficult to get a good pic but will try.

Thanks again-

Dave:
So, to follow up, I have a question. When you say "I have removed the teak decks" : did you do that yourself or possibly you supervised it. Is the original plywood sub deck still there? If so, can water be seeping down into it? I am certain that my staining is coming from that area (which one cannot see) and I don't see any evidence of it coming from the bronze.
I am attaching a photo of how it appears on my boat.
Regards, Alan.

It won't be the bronze rub rail that's causing the staining, it could be

1. Somebody has fitted screws that aren't Silicabronze, and the staining is rust.
2. As already stated colour from teak, which would mean that water is getting in somewhere.

Difficult to tell from photos.
