Straightening 30mm solid bar - best way?

[f2tmg]

Hi all, I race a kart and the axle gets bent on a fairly regular basis, I've been using a press but was hoping there is either a different way or an ideal technique to get it done easier and quicker.
I've seen getting them rolled suggested but I can't find anyone local who even knows what that is.

Any thoughts or ideas welcome

if the bend is only in one direction and you are good with a set of slip rolls then you could use that and a straight edge i suppose, but i am assuming you dont have any slip rolls or you would have already tried it...i would think a press would be your best bet with that size bar as it will take a lot of force to bend it it

Does the part of the axle that bends actually rotate or is it simply bending because its been a bit lightly designed?

Some photos would help, perhaps there is a way to eliminate the problem altogether.

Sounds to me like it needs to be made from better material in the first place.For the moment i would stick with the press.

He is karting, you want the axle to bend in the event of a smack if not the damage will be transferred to the chassis which is a lot more of a large headache than a bent bit of round bar.


Decent size fly press, v blocks, a few ally blocks with the rad of the axle in (preferred) and a decent decent straight edge or flat surface, I'm not sure how rolling would work in this instance because you will need to over bend the axle to make it straight otherwise it will just bounce back to the old shape. Also assuming the bend is not to bad there will be a limit of what can be realistically straightened.

Another vote for a fly press and some blocks. Might be worth getting your own set up if your paying a guy to do it they sint dear second hand

Can't see why you don't use better steel as if 20 mm solid bends so will the chassis I can't see it being much of a cushion
