Default Mini shaft / rod straightener ?

I am trying to find if there is such a tool as a shaft / rod straightener ?

I am fed up with collecting heli shafts ... motor shafts .... and the like that have a slight bend ... I have straightened a few but they still have a slight 'wobble' when run up.

If there is a tool out there that can straighten these - it would be a tool from heaven for me !

Needs to be able to straighten up to 6mm steel rod ...

Maybe this might Help Nigel, after straightening the shaft, roll it on a piece of glass panel to check for straightness.

With Nitro Engines to Straighten out the Crankshaft where the prop attaches to, I chuck the Treaded part of the Crankshaft to a Drill press, attach a dial indicator to the drill press with a Magnetic base, put the dial indicator shaft at the lowest part of the crank, check the run out, and tap the crank shaft with a small mallet to straighten it, and keep checking and tapping the crank until its straight

I have used a drill press as a arbor press. I just supported both sides of the shaft, and then used the drill press chuck as a controlled force. I could push just a little more at a time until it was straight.
The rolling the shaft on glass is a good way to find the high spot.
