At the base of the weld

Is that a cannondale….. 😛

yup!

Looks more like a scratch, If it was a crack it'd be bigger than that IMO even if it was starting

weird place for a scratch tho and also on he edge of a weld 🙁

Difficult to say. I'd say scratch, though it is an unusual place.

Get a permanent marker and put a clear line at each end of it and see if it grows

I will do that and also measure it

thats not a crack

what length forks are you running, have you exceeded the length on the warning sticker?

yep

what jedi said

Looks like a crack to me, sorry. I'm no expert though.

I'll buy your vanilla r off you.
Oops, sorry…

running 140mm forks

Which bike as a matter of interest?

prophet

it doesn't look like a crack to me n i'm a welder

Yep. Fubared Rob – send it to me to make sure it is disposed of properly 😉

Congrats by the way! 😀

it looks like a crack to me from where i'm sittin'

worry about it when you're picking your teeth off the floor 😛

It does look like a crack to me and Im the Chaiman of the Master Welder's Association.

you are Chairman Mwa?

suits you

I could get the NDT guy at work to check it for you using eddy current if you're ever in the Reading area, but seeing as you're in the Peak Distict unlikely!

TCut has removed a flake of paint – no crack 🙂

Chairman Mwa?

Ex sadly. I've had to resign due to my assumption on the above picture being incorrect 😐

didn't think so mate.you sometimes get a tiny groove between the weld and metal when the welds a little to hot and that can catch dirt.

Easier to use Ardrox spray penetrant and developer. Most welding shops should have a can or two lying around. It'll show whether or not its a crack and how severe it is.

How does it work?

You spray the penetrant on and leave to soak for a few minutes, clean off the excess then spray on the developer. If it is a crack it will show up as (usually) a red line in the developer. The deeper the crack the thicker the line. It's used for checking critical welds on pressure vessels and aero structures. Better for surface cracks than ultra sound.

Sounds good – jontawn is a welder so hopefully he can help me 🙂

If it ends up like this yer fecked!…I dont think its a major crack though,looks like a slight flaw in the tube to me,Its not a stressed part of the frame either so nothing strength wise to worry about. 😀
