Is there any electrical reason not to put the bearings in a metal bushing

Not if the frame is grounded. Otherwise, it's an attempt to isolate
the frame from the armature. that will prevent a shock while using the
tool, but could kill you if you touch the motor shaft & a good ground
when the insulation fails.


I was thinking something along those lines. There is an internal brush like
contact that touches the metal nose/frame of the router when it is assembled
properly. I suppose its time to get out my meter and see how good the
ground is.
