Why is my bone scaling when I rotate? I don’t have envelopes on:
bone is being rotated along the Y axis… at 65 degrees, it appears to have shrunk the vertices… at 125 degrees, it certainly has shrunk the vertice group:

Unparent the Mesh from the Bone or Armature and do Ctrl-A on the Armature Object in Object mode and again in Pose mode with all Bones selected. Then goto Edit mode with all Bones selected and do Ctrl-N, then parent them again.
I dig the way you expect me to sniff out the offending bone in amongst all that! I assume the problem is what happens when you rotate BO:Core? Bo:TeslaRig is parented to it and the Vert Group parented to TeslaRig distorts when you rotate Core. That’s because the Y-Axis of the 2 bones are 1) not alligned and 2) offset from one another. If you rotate BO:TeslaRig around it’s own Y-Axis then everything works fine.
You may have problems if you move either of the bones, but you could try either 1) unparent TeslaRig from Core and use a Copy Rotation constraint to have TeslaRig rotate with Core but remain stationary while doing so or 2) use an IPO Driver to do the same thing.
