Removing stanchions from bases.

[jimbouy]

This has kind of been covered in the past but in reverse.


I have to replace 2 cracked stanchion bases. I've removed them from the boat no trouble and removed the bolt that secures the stanchion. But the actual stanchions are well and truly stuck in the bases.

Will heating them help? or shall I carefully try to cut away the bases?

Or shall I soak them in cola.

Hi Jim ...... gentle tapping around with rubber hammer ?? Heating will discolour the base and stanchion itself.
Cutting away may be the only solution - but can you get replacements that match in with others ? Or will you have to change all to get match ?

Easing oil, rubber hammer ......

I'm not sure if they're like the ones on our Moody (aluminium). When changing cracked ones we literally have to drill the metal base away - it takes ages.

New bases are supplied with a nylon insert - presumably so that it doesn't happen next time!

Hi Jimbuoy!

Had this problem a few years ago and tried everything from heating it to soaking for days in oil. I'm sorry to say nothing worked and I had to cut the stanchion base along the line of the stanchion and split it open.

The solution, which has worked for the last 17 years, is to remove the stanchions once a year (mine come out anyway if I'm in the UK and laying up ashore) smear Blakes seacock grease on the stanchion and inside the base, and re-insert. Because this grease is non-hardening and totally waterproof, the stanchions will never corrode or bind again.

Hope this helps,

Jerry

I found that the quickest way to get them off is to use an angle grinder with a metal cutting disc and make one cut, not deep enough to cut into the stanchion, but deep enough to allow you to open the slot with a big screwdriver or a chisel (twisting it) to break the grip that the base has on the stanchion. This avoids the potential for damage that might happen from heat or hammering.

Angle grinders are now cheap, in the DIY stores, and though I bought mine specifically for this job a few years ago, it's proved invaluable since.

Angle grinder was the only one that worked for me. Combined with club hammer of course.

well very gentle heat followed by brute force has done the jov nicely.

I'll grease them up before fitting them into the new bases.


Thanks all.
