    any ideas on how to bend driveshaft?

    I am making a coupler/impeller tool out of a driveshaft, and I thought using a torch would heat it up enough so I could bend it, but this thing is not moving.

    anyone have a better idea? have a machine shop do it maybe?

    Did you use an oxy/acetylene torch? I would think if you got it red hot and continued to apply heat it would bend in a vise. Hmm...
    I may have to give that a shot.

    it must be the torch I am using...I do not have anything that sophisticated, just a butane torch I grabbed from HF. the metal did get pretty hot, but not like glowing red or anything.

    having never done this before, I had no way of knowing...meh.

    if you can get it to work, any chance I could just send this to you?

    I wonder if a map gas torch would do? I'll give that a try 1st ( tonight) and let ya know. If that doesn't get it, I'll use the oxy/acetyl torch.

    why bend it? I just put the stub shaft in a vice. Then put the spare drive shaft I'm using in and throw a pipe wrench on it. I guess you could cut it down and machine the end to fit a socket if ur worried about torque to a 100 foot pounds.

    A real impeller removal tool is not very expensive.

    Often available on eBay, and directly from Randy at Watcon.

    And it will fit in your tool box

    My thoughts exactly. Just cut it and weld a large nut on the end. Like Keith said, removal tools are cheap, but since you already have the shaft you make one with the nut on the end a little cheaper.

    Need to get it red hot in order to bend it.

    Get a long piece of pipe to pry with.

    Place it in a vice where you want it bent, and heat it up.

    Slide the pipe over the shaft and pull down while heat is applied. Should bend no problem.

    A service garage, or any place that does mufflers would have an acetalyne torch.

    I wanted to bend it for leverage while the engine was inside the hull so I could get the coupler off easier.

    I in fact took it to the muffler shop I get all my car repair work done and they hooked me up.

    thanks guys!
