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.

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.
