Gentlemen.
Thought I'd share a job that's been through my shop this week.
I was sent this Spindle Cartridge assembly from Perth. It's had a bit of history. Its a #40 taper.
They had snapped the bolts that hold the drive keys in. Must be a boomtown thing. Just Mig weld a new set in. While its assembled and sitting on the bearings.

I don't know whats gone on to the face of that spindle. I suspect they tried to peen some meat into the key slot.

I spent half a day last weekend getting the broken bolts out.
