I accidentally did that by 1/2 an inch when building my hydraulic press. The ram is a touch on the heavy side so I used its own power to lift it in position off of the press table. Turned out my measurements were a little off.
Sounds like a feeble excuse to me, what if they all happen to be using their toys machines?

Just teach them how to do things safely whilst you watch them, otherwise they'll only go and do them behind your back without any guidance I was allowed to use any tool when I was growing up
I've only ever seen one broken Record 36 and it was still usable despite the hole in it. They are a nice vice, they have more clearance around the slide than more traditional looking vices.
I do like that... and have the exact same vice too Also have a couple of other funky jawed vices, although sadly not a fractal jaw one as they sell for literally thousands now.
