Titanium frame crack repair

[Flowta]

Hi guys

 

I was looking around the storage at varsity for bits and pieces for my engineering project and found an old Titanium frame. Looks just the right size for me.

 

Had a closer look and there is a crack on the underside of the downtube just below the headtube welds. Is it possible to get this repaired? or is it not advisable?

 

Thanks

anyone?

You found it in the dustbin...keep it there.

 

I wont trust a welded ti frame.

[RodTi]

Pics would be cool....

 

Any idead what frame it is?

 

And as for welding - well, whether you ought to trust it will surely depend on whether or not you trust the welder?

[GoLefty!!]

Ti can be repaired but you will should try not to use the person who welded the frame...

 

I asked the blokes at the faculty if they know of anyone who can weld ti competantly and the answer was No.

 

Suggest you try the blokes at Produx. They dabbled in Ti welding at one point.

It's not the welding that's the problem but the heat treatment afterwards. And that's the reason it broke in the first place.

 

The frame is toast, but don't dump it. Saw off the head tube and make yourself a nice titanium pencil holder from it.

 

Saw off the dropouts and file them a little bit to make cool bottle openers.

 

Saw off the downtube and make yourself a nice titanium towel rail from it. Your wife will love it.

 

Saw off the seat tube and install a bottle cage. Put this on a stand in your kitchen and keep a spare cycling bottle in the cage. It makes a great conversation piece, especially if you saw off the bottle's top and plant some Peace in the Home in there. Chicks will go gaga for your interior decoration touches. I'd even go so far as to put a saddle in the seat tube, just so that people know it is a recycled bicycle part.

 

I'm still working on what you could do with the BB and its array of stubby tubes.

You can make some very nice rings from the ti tubes. I once gave a ti seatpost to a jewler friend and he made me a very nice ring. But he said the next time I ask him he'll tell me to get lost. Apparantly its nearly impossible to work with the ti.

anyone?

 

maybe you could start by telling us how many frames you've broken in the last 18 months first.

 

up to three now is it?

Lots of people say this but I find it not true. Ti does work-harden a little but I can't see how your jeweller friend had a problem. All he had to do was saw and file. Even at its hardest point Titanium is still way softer than mild steel.

 

There is more myth in titantium than in Kryptonite.

He said it were very hard to polish out small scratches.
