Freeing up aluminium tube seized in tube (SeaKem?)
Submitted by pelagicyachts on Mon, 2022-03-14 08:54
hi guys
Aluminium question ... (anodised alum if that makes any difference)
THe back stay for my outriggers has a tube the slides inside a larger tube (shown below) - the idea being you can lower them by removing a locking pin to get under bridges etc
THe back stays have been sat on their sides for a few years and the tubes appear seized/corroded together.
Any ideas on what i can do to free them up
Heat?
Acetone and brake fluid?(found online..)
cheers

Heat is likely your only option-the oxidation in between will make it very hard especially if you are unable to twist it.
The bottom one doesnt look like aluminium though?

Yep my thoughts Rob, light
Yep my thoughts Rob, light heat on there.
I do a lot of oxidised 'removal' for a client and it's usually a 5 second job.
Try soaking etc Clint and if no luck give me a call. I'm away end of the week though for a week.

If you havent used heat on ally before, draw a texta line on it where you are heating.
When the line disappears, stop heating, it will melt if you are waiting for any redness.
Try it, if wont move quench it and try

I've played with it a bit and know how quickly it collapses.

thanks guys - yep both are alum - anodised to look shiny
I was thinking of a bit of caustic soda as well - although that may just eat the good metal and leave the bad....

Try
CLR and leave overnight.
Can put a plastic tube over the pipe slightly larger than the dia of the largest part of the pipe and put a hose clamp around the bottom to form a cup tighten clamp fill with CLR overnight/day or two.

I think this might be the answer. I've used CLR to free a few things over the years.

Boats
It's never, ever ending.
To keep a boat in A1 condition I'm wondering what the real hours on the water v hours in maintenance is?. I'd say it's close to 1:1.
My wife understands why I clean my rods n reels in the shower....

Certainly for bigger boats,
Certainly for bigger boats, especially penned boats. I guess the upside there is you can spend all weekend staying on the boat for not too many hours upkeep. The downside is in winter when you need to maintain but rarely use it. That's boats for ya!
