the real question is: why do you want the bevel? I know that some guys put a smooth curve on the rod ends....but...personally i just run an emery board over the end to get rid of any burrs....and good to go....
My guess is that manufacturers put the bevel on so it is easier to put into the leading edge fittings. My personal experience is that the beveled rods fit easier than non beveled so I would agree. However none of the light Dynamic rods I have on the Acrobatx UL are beveled, they are all cut straight. I have no problems getting them in the fittings.
So are you saying it is not worth the effort?
