Rotating a bone along one of its local axes I am doing a complex mechanical hand rig and i want to rotate one of the bones along its x axis but Blender doesnt allow me to do that. Is there a way to do that or this type of rotation isnt supported by the program?
Have you tried hitting X one extra time? eg. R >> X >> X". Maybe you have to do two Y's OR two Z's but one of these options should get you there.

Here are bones rotating in their local axis.



If you are in Edit Mode, X May be close to equal (global vs. local).
Instead try Y &amp; Z:
