pop_ Posted May 25, 2009 Posted May 25, 2009 I have an aluminium frame with a crack in the bottom tube where the bottle cage attaches. Does anyone know whether such crack can be repaired successfully, and if so, where or who can do it? Note: the frame has long passed the manufactures guarantee. https://www.bikehub.co.za/smileys/smiley19.gif
jagwil Posted May 25, 2009 Posted May 25, 2009 There was a thread a few weeks ago about a frame repair. I can't remember whether it was an aliminium frame. The repair looked very professional.
Johan Bornman Posted May 25, 2009 Posted May 25, 2009 That particular crack is in the worst place it could be. The material there is very thin and a weld will just worsen things. I say it is toast.
Azonic Posted May 25, 2009 Posted May 25, 2009 Hacksaw, cut the tube all the way through. Get a small piece of alloy turned to size, pull the frame apart and slide the brace into it. Weld it, slide the other side of the frame over the crack and weld again. The welding shop that fixed my frame is VERY good. Fixed my broken frame like that a month ago, and it's probably stronger than it was before.
wackwack Posted May 25, 2009 Posted May 25, 2009 Jeepers - How did that happen? Looks like you took a 9mm to 'remove' the bolt.
Free Posted May 25, 2009 Posted May 25, 2009 I had an old mtb welded that cracked right trough on the chainstays. The guy from the weld shop welded both sides to reinforce it. He the smoothed the welding with steel putty and I resprayed it. Looks as good as new and its been lasting for a while now.

I agree with JB, the frame is toast. the cost of fixing it will buy you a very nice secondhand frame here on the hub or a not too shabby new frame. There was a red merida frame going for R1200 not too long ago.
