Hi silyavski,

Many thanks for the reply here. I was not welding as don't know the first thing about welding. I have no speakers connected to my computer. I may have had a vacuum running but I doubt it as I was hardly intending to cut much the only other thing on would have been a Makita radio and dehumidifier.
I don't think tool slippage was an issue in this case but thank you for the thought. One of my jobs on the horizon mind is to make a part to hold my tool holders.

As for an update on what happened I was stood right in front of the mill it started to go south and before I got to hit the E Stop the electric supply tripped and I was in the dark.

All the best
