    JB welding a cracked frame

    Hi, i am wondering if anyone ever tried using JB weld to repair their small little crack on their frame? It say it will bond to almost any types of metal, and once it is dry, it is as strong as steel. What do you guys think?

    You're going to hurt yourself if you try. If the frame is steel or ti go to a welding shop. Aluminum, toss it.

    Depends on where the crack is and how much stress is put in that place. I have used JB Weld to fix cracked radiators and power window slide rails in a car. It's amazing stuff. But everything has its limits.

    Try it and let us know.

    I wouldn't...

    I've used JB weld to fix motorcycle engines, the dropouts on my hardtail, and a few other items. I'm a big fan of it. That said, I wouldn't trust it for a frame. If it's not properly mixed and put on in the right templerature range, it tends to fail.

    Get the frame properly welded or replaced. JB Weld is more of a temporary fix, not a permanent one.

    if it is steel you might look into getting the crack welded or better still have it brazed depending on the type of steel and location of the crack. Post an image and give us more data and I'll bet you'll get all sorts of options.... nobody suggested twigs & duct tape to brace it.

    I think someone should look into making frames out of JB Weld

    A few things to ponder

    risk vs. reward

    Darwin's Theory

    comprehensive medical and dental insurance

    Reminds me of a story my father told me about a guy he went to HS with. He came to school one day with a horrid paint job on his car. When asked what happenned he explained that it said right on the can of paint that it went on so smooth that you could apply it with a powder puff. And the rest is the stuff that legends are made of...

    I might be inclined to take a chance on a window slide or a radiator, but not on a bicycle frame. If this is a mountain bike frame that sees typical use/abuse , IMHO it should be cut up and sent to begin it's new life as a Saturn or Toyota.

    I wouldn't trust it on a bike frame.

    However, on my lawn furniture I'd have no problems
