That is my conclusion, too... The truck was not old, possibly 150 hours, maybe less. Not sure.

I wonder why LHR allows for 1/2" bits in the designer (yes, I know they actually do _NOT_ sell such bits) if they can break the machine. Now that I have taken out both bearings I can see that the 6002 at the bottom was in worse shape than the 6000 at the top.

Well, lesson learned: use no larger bits than 1/4" to do bottom cleaning on paulownia, watch out for bits becoming blunt and do not take more than 1-16" at a time... Or maybe stop carving Paulownia... but now that I know how to find may way around the Z-truck I might be tempted to continue with Paulownia and see how well my carving tools survive. Paulownia is so lightweight and so easy to process: no knots, little chipping.
