question for the machinist trueing small rod

[losthelm]

I have made a bunch of stainless mandrels but somewhere along the way they got slightly bent.
I suspect the post office droped the box.

As for material its stainless tig rod mostly 308 but some are 309 and 316
These mandrels are all about 3/32 and range in lenth from 8"-12"
The deflection is roughly 1/32-1/8 over the lenth.

My first thought was to run them through a thick draw plate of some type or posibly a slip roll or jewlery rolling mill.
Before investing in more tools and equipment what is the best option?

Hi Losthelm, Is it possible to just tap them straight with a hammer on an anvil or stump? What are the rods used for?

If it was a sharp bend tapping them strait would work well but its more of a gradual curve over the intire lenth of the rod.

Not sure if this would work, but we used to straighten bent bits and small nails by chucking them in a drill, then holding it so the rod was lying flat on a block of wood and running the drill.

That only means more, lighter taps. It'll work just fine.
