I had been looking for an airplane propeller for some time to hang up in my shop. One of my friends told me she knew where one was and that she would get it for me. I did not know that it would be bent. Any ideas how to straighten the prop? I thought about heat but I have never tried anything this big before. I was also concerned that aluminum of this size would dissipate heat rapidly. Any help would be greatly appreciated.

Man, I've seen props on operational aircraft up here that weren't much better than that one.

Hang it up bent. A good, used propeller hanging on the wall is cool. A bent propeller is cool, and has a story.

As the Prop will not ever be in service again here is my take as I have repaired/ straightened a few rims and forward controls.
You are definitely gonna need some heat and I recommend a nice oa set up with a rose bud.
Heat that puppy to about 750 range and add a slow pressure to the bend. Not sure if a prop is hollow but if it is we are gonna have a issue and will need to sling/strap and pull the bend out.
the key to success is use your common sense and take your time.
Go slow and don't throw too much heat at it.
The funny thing with aluminium is when you add the heat most of the bend will come out naturally. A little heat goes along way and I also use a raw hide hammer and it does wonders.
Good Luck and give a shout if you need more help.

Hang it up bent, it would be even more interesting if you found out the story behind it.

There is an aviation salvage yard in Phoenix AZ I used to deal with for unusual aluminum pieces. I do not recall the name, but google them and you'll find it. Contact them and ask this same question. An aviation salvage yard might be a good start, or contact the aviation museaum at the smithsonian as they are always doing restoration they may have an idea how to accomplish this with the least fatigue on the metal.

In all the years I flew, never got a bent one, but maybe the pilot forgot to extend the gear
Anyway it looks cool like it is, the advice given on bending is good, but I have no idea how well it works.
Good Luck, let the forum know what you did..

Heat sounds like the way to approach this project, but I will be cautious and call some of the experts mentioned, in order to avoid any problems. If you have any other ideas please let me know.
