Default Straightening and truing wheels?

I have an idea for a tool to re-establish a wheels roundness and re-align the hub to the rim. Before I build one I thought it would be good to see if and how others have done this.

Interesting idea. I would thing that minor work could be done but if it was too bad out of round, you would remove too much material and the wheel would become weak and break. Just a thought.

If its a heat and remold method, it may work but again, once its heated to move it enough, you again may loose the integrity of the original casting/ proccess.

you will have to use heat in order for it to stay in the shape you want. it heats up when it's impacted which is why it will bend and stay that way. becoming weaker makes sense if you think of the molecular structure.
or if anything it will be brittle.

Basicly I'm going to mill apiece of aluminum the same diameter as the inside of the wheel (with three finger holes so I can put it in and get it out) and put a very precise whole in the middle to accept the shaft from my Losi wheel balancer which, bolts to the hub. When I insert the "Wheel Tree" it will force the wheel back to round and pull the hub back to square with the rim. Then I will experiment with the heat. I'm thinking a torch to the Wheel Tree and hub yoke will provide sufficient heat for minor problems.

Thanks for the feed back. All additional input will be appreciated.

P.S. I do not know anything technical about plastic and what affect the heat will have but I do see some practical limitations that limit how much heat can be used before making things worse e.g. the CA, the inserts or the tire may deteriorate before the plastic become warm enough to remold. Any specific input on this aspect would help me when I get to the experimenting stage.

Just toss it in a preheated oven. No need for torch.

If it works you have a good product idea. Especially for the Losi 5ive's. They bend wheels alot and those wheels are $$$$$. So people would buy this tool for them.

I was thinking 225 for 5 minutes??? I do not know if that would provide enough heat to allow the plastic to remold and still be cool enough that it does not damage other parts. A set of four could be affordable too.
