Not to keep on with the drift...
When I pushed the axle thru the trainer it pushed the freehub ratchet out of the hub just a bit - that only allowed the threads to engage about 1/2 into the frame on the drive side.
I didn't notice this, wasn't even something I was looking for, I simply torqued up the axle. One pedal stroke and freehub parts spun all over the place.
If the freehub didn't explode, and the bike was only partially engaged - I could see something bad happening to the frame.
