Jonathan there is two grub screws and I used Truloc shaft retainer as well both on shaft collar and the top bearing. But the forces act on shaft up the spindle or sideways, but not down(trying to tear the shaft off from the spindle, if I can put it in this way). So far it worked well for quite few hours with no problems at all. If something changes I'll post info asap
