How to straighten 32L axles? I have a number of the 32L technic axles, but most of them have some bend to them.  Is there a straight-forward way to straighten these?  Trying to bend them by hand has not seemed to change anything, and I'm afraid I'm going to snap them if I try harder.
I'd suggest storing them straightened up for a while, if possible in 32 adjoining 1x2 bricks with cross hole, and add a few layers of bricks to hold them in place. At least it's a pure LEGO solution, but I'm not sure how efficient.
