Copperslip

[Snorrarcisco]

I was watching this video on you tube of someone doing the conversion between a centre lock to 6 bolt bearing discs. Now he gently applies what looks to be copperslip on the thread of the wheel section (the shimano centre lock part) and then inserts the converter on it.

Is this necessary? in what ways and where do you use copperslip if you use it at all?

I use coppaslip on any thread that I don't want to seize, especially if it's a steel thread into an alloy component. The compound works like a lubricant, but also prevent oxidisation and electrolytic reaction.

On pedals and inside the bottom bracket after a clean up.

I understand why some people lubricate threads, but it's not actually correct to do so.
Threads are designed to be employed "dry", and associated calculations (e.g. tightening torque) are based on this condition.
Just sayin'

Copaslip isn't a lubricant, it's an anti seize compound.

Copaslip isn't a lubricant, it's an anti seize compound.

And the difference is?

 

[Andy_R]

One is designed purely to lubricate (thus, lubricant), the other is designed to stop things getting seized (thus, anti sieze). Lubricants are designed to allow bits that are supposed to move against each other do so. Anti sieze compounds are designed to prevent things that aren't supposed to move against each other from getting stuck together. Simples really.

Not a lot until you need to undo the bolt, then it makes all the difference.

Use locking compound. As well a preventing critical fasteners from coming undone, it also acts as an anti seize barrier.

Dry torque is another myth. With the pressures involved in thread-on-thread contact any lubricant, compound or ungent flows like water away from from the point of contact, making little real difference over "dry" tightness. Just sayin'.

Anti seize compounds still allow this contact but the compound acts as a sacrificial agent and corrodes much more readily than the metals it protecting. Moly based anti-seize is better suited to applications where heat is involved, although copaslip type compounds will do at a pinch.

 

[Oldfentiger]

Anything can be a lubricant - even water.
It's true that typical oils can be forced away from pressure areas, but many modern lubricants, coppaslip included, contain solid lubricants.

 

[Drago]

The particles within aren't lubricants. They're actually abrasive, hence it being an antiseize compound and not a, er, lubricant.

That is why you're not supposed to let it anywhere near caliper guide pins and pistons on cars brakes.

 

[Oldfentiger]

I could agree with what you're saying.
But then two of us would be wrong

 

[Drago]

Hell, we both know I'm rarely right, and when I am I'm more surprised than anyone!

I think I've applied some to my seat post but not anywhere else that I can recall
