Reshaping PVC pipe

[The Rock-a-who]

Hi all,

I'm working on the hand controls of the comic-version of the Rocketeer.

I have some rings made from cutting PVC pipes, but for the ring that goes around the palm of the hand, I need to reshape it some and don't know the best way to accomplish this.

The rings are from a 3" pipe, with a .25" thick wall, about 1" tall/thick.

I thought heating it with a hair dryer might do the trick, but with the thickness of the pipe's wall, I don't think it could generate enough heat to soften the plastic. Other thoughts include using a blowtorch, or even setting them in an oven at a low heat (200 degrees maybe?) until it softens.

But I wanted to post here and see if anyone has a better idea to do this.

Basically I just need to soften it enough to change the shape from a circle to (roughly) an oval/oblong.

Thanks

EDIT: FYI for anyone's interested, here's a few shots of the hand controls in the comic.

I have not tried to attempt what you are suggesting, but I can tell you that if put a blow torch to the PVC you will just burn it. I learned that helping my Dad's plumbing business while going to college. I'm not sure if PVC is the right material for what you want to accomplish.

At the link below. They put some PVC in boiling water to make it pliable.

Could a few quick passes with a heat gun soften it just enough to get it to shape?

You might consider using SINTRA. You can get it in various thicknesses and shape it easily with heat or hot water.

A heat gun will make short work of it, turns PVC to a noodle... Just don't rush it or else you will blister the surface...

Heat gun works much better than a torch, but as mentioned, it will blister rather quickly

Goes without saying that if you are going to heat the PVC to the point that it could char or smoke such as using a torch, do so outside or somewhere with good ventilation.
