Press Tool Trick

Picked up from a technician at work who'd pressed many a bearing:  Put a magnet in the back side of the press tool so it sticks to the bottom of the arbor press ram

Tool sticks to the ram and automatically squares itself!  No need for 3 hands to hold the part, the press tool, and the arbor press lever:
