What!! Evapourust is getting expensive, plus it is only the top that needs treatment. 😁

[Johnny4428]

This does not look good! Further investigation required.

Uh oh! Looks like crack. 😩

[McCabe-Thiele (Ted)]

Is there a corresponding mark on the other side?
Could it just be a gouge mark

[Rozabikes Tim]

Is it just me, I now see there is a crack or whatever but on looking at that initially I thought you were showing us the damage to a red wire???

Just the edge of the bike lift!😂

[Johnny4428]

There is no mark or sign of a crack on the other side, so at the moment I’m thinking it’s just a gouge from maybe a trapped stone or something? But if I’m in any doubt I will look for a replacement.

[Laverdaroo]

That looks a bit dodge to me, if it’s deep get it skimmed, I did but only cos I had loads of ‘meat’ left but I think I’d be changing that anyway Johnny.

You’re probably right Roo. Not deep, barely feel anything with the fingernail. I will investigate further before looking around for a replacement.

[Orcade-Ian]

Can’t imagine it being a crack in that material Johnny, have you done a ‘ringing’ test?  Damage looks more like a wheel dragged out from under a pile of heavy stuff with something sharp under it.  I have a can of penetrant flaw detection dye if you want to be certain.

I did wonder about some sort of acoustic test will try that and see what the results are. Was going to clean it up and paint the centre but will have to be certain of its integrity before I spend any time on it.
Thanks for the offer of the flaw detecting magic gear Ian!

I agree with Ian, unlikely in this material.

Looks to have been scraped by another object, then still used which has flattened any burr.

They are really, really tough material spec .... at the end of the world there'll be just cockroach and these old 70s Honda disc 

There's no tracking at either end of that mark either, not inboard into mount flange or outboard in evidence of how a crack would ordinarily propagate.
