Stanchions

[Craig]

Any suggestions on how to best remove the old aluminum
Stanchions?

[John S]

Will they twist in the sockets or move at all? If so I would just keep working at it. I've been successful with some stuck SS stanchions in the past with a strong steel rod through the top and twisting and lifting. It's a serious workout and it might cause the aluminum to fail where you are twisting and pulling. But it might work. If the aluminum is so corroded that it is really stuck I'm not sure what the best course of action would be. Good luck.

the olson 30 fleet used a 1" easy out to grip/twist the stantion, (usually after being broken off). they also used a ~1" pipe tap (actually a 3/4" pipe).

you will need to use either aluminum cutting fluid or penetrating oil, or automatic transmission fluid to penetrate and lubricate (not lock-ease or wd40 or sewing machine oil). you want a fluid that has a high surface tension so it goes deep in the hole. you dont need much by the way and time will not help much.

tap with a peen hammer, very short taps, with a very small hammer, you just want to create a vibration in the aluminum, and apply torque. work it back and forth with the hammer pings and the wrench.

oh, by the way, if rumor and measurement serve you well, the rudder is a NACA 4 foil, (NACA 0016, or 0018 depending on which mold) set slightly off the water axis so it lines up with the boat bow down and the keel is a NACA 5 foil very similar to a certain classified submarine fin. Can we say that on the internet? You can make templates easy enough. Build plans which include offsets and profiles do include the foil section for the rudder, but not the keel, as far as what i saw when i saw them.

I was going to say "pull up" but you probably already tried that?   one of the greatest features of the sc27 is that they (should) pull right out, easily.

 

good luck!

PB blaster as seen on tv or Kroil give them time 2/3 days they will work....

Was the submarine the Costa Concordia?

Wish it was that easy. But 30yrs of corrosion has frozen them in
place.
Hope to see you at 3 BR

Last tine I tried snake oil it wasn't effective but I'll try again who
knows.

go inside boat and remove the bolts holding the stantions down, then try again. ;-}

and as with the O-30's, usually have to break them off and use the easy out. you can get one cheap at Harbor Freight. the stantions get bent and they grow in diameter at the deck, and until you get in there, and use the easy out, you will have a hard time as you have about 18 square inches of aluminum corroded into the glass in the hole.

Try putting a towel soaked in boiling water on the glass socket (inside the boat) while you empty a can of 'freeze spray' inside the metal stanchion tube from outside. Drill a hole / remove the top of the stanchion to get freeze spray in it, and be ready with vice grips on the stanchion.

Fire & ice? Might have some merit. Our local guy suggested heating and cooling the stanchions with a
torch while tapping with hammer

All good ideas...

One more...try soaking the frozen parts in coca cola....it works as well as any penetrating oil...better in some situations.

Freezing the tube and warming the glass should loosen the fit .002 to .004", which will make an appreciable difference. Heating the tube with a torch will soften the polyester and might let you remove the stanchions as well, but freezing the tube is less invasive, if you will.

after all this does not work, use a recip saw and cut off the stantion 2 inches above the deck, and carefully cut a slit in the tube. You dont need to cut all the way thru, just remove most of the aluminum and as you twist the tube it will collapse and come out.

Call your friends at Northwest Rigging our travel expenses and per diem may set you back a bit and repairing the sockets when were finished but we'll get the stanchions out. BY the way if they have been stuck in there 30 years, why are they coming out now?

[craig smith]

The Kroil did the trick. I was able to break them free with a pipe wrench after a few hrs of soak.

The broaches and close encounters with our competitors left us with several bent and broken stanchions. I had drilled out a couple last year to replace them but this is not a good method as it  is difficult to keep a bit centered.

Thanks to all for your suggestions.

I had the same problem with Jersey Girl years ago. My solution was to
use a saws all and carefully cut the stuck piece into vertical
sections then pulled them out. After the first section there the rest
just pulled out.

The replacement stanchion design I did is designed to break
approximately 2" above the deck making future removal much simpler.
Let me know how the replacements that Gary fabricated works out for
you.
