Re: Stus-List Rusted cotter ring remnants in anchor roller retaining

[kelly petew via CnC-List]

Thanks for all the advice.  
I tried vinegar, and it worked!!
After about 24 hours of soaking in vinegar, I was able to easily extract the 
inferior metal, using a hammer and a punch.

Re: Stus-List Rusted cotter ring remnants in anchor roller retaining pin

[Russ & Melody via CnC-List]

Hi Pete,

I expect it is spring steel if you're dealing 
with a (split) ring. So it's difficult to drill.


The simplest method is to dress it flush with the 
pin surface as best you can, file or grinder, and 
drill a new hole ~90 degrees from the old. A 
little away from the old path if you have enough 
material towards the end so you don't bump into 
the old ring on your way through. It helps to 
flatten the surface & centre punch where you want to drill.


If you try acid then get the strongest that you 
are comfortable working with and wear eye 
protection, gloves, blah blah. Don't worry about 
the S/S pin, our 93% strength sulfuric acid pumps 
& piping is stainless steel. Then when ready try 
to drive it out with a pin punch instead of drilling.


Cheers, Russ

Pete,
For what it’s worth, Citric Acid will eat the 
rust(iron) and not effect the stainless.  I am 
not sure how you would use that info.  Maybe 
soak the area intermittently with a 10% citric 
solution.  I don’t think it will harm your fiberglass.

The powdered drink “Tang” is high in Citric acid.

Due to inferior steel, a cotter ring has rusted 
badly, and I am unable to remove the remnants from the pin.
So far, a hardened-steel drill bit (Irwin 
brand) is simply enlarging the hole around the 
edges, but not removing the ring remnants.

Is there chemical solution?
Any thoughts would be greatly appreciated.

Pete, 
For what it’s worth, Citric Acid will eat the rust(iron) and not effect the 
stainless.  I am not sure how you would use that info.  Maybe soak the area 
intermittently with a 10% citric solution.  I don’t think it will harm your 
fiberglass.  
The powdered drink “Tang” is high in Citric acid.

Re: Stus-List Rusted cotter ring remnants in anchor roller retaining pin

[Dennis C. via CnC-List]

If the cotter ring is garbage metal, it should grind easily.  Grind the
remnants flat to the clevis pin.  Remove the pin.  Throw it away.  Buy a
new clevis pin.  Use a stainless cotter ring.

Clevis pins can be found here:
