<human>: Can you summarize the given text in a few sentences?

I build electrical control panels.  I decided I'd show up for an optional double time Saturday shift and just get work done.  I just finished cutting a hole in the front of the steel door to mount a touchscreen PC, a beautiful clean cut rectangle. Next I drilled a hole for the emergency stop button but the whole is just a prep hole basically. To quickly cut out a larger hoke we use a hydraulic knockout which basically compresses the steel to the point where it shears through to the hole size you want based on the size of the ends you put on it.  

Well I hadn't used it before but I had seen it done so I figured I was OK but I assembled it wrong before pulling the trigger to apply pressure. Instead of staying plumb/strait and pulling right through the thing bent on an angle and locked up and I couldn't get it back out of the hole.  It's a threaded axle that connects to the bit and then back into the tool. Bent a good 20 degree or more angle in that and had to disassemble the whole tool.  When taking it apart I spilled hydraulic fluid all over myself and the floor.  After realizing I couldn't fix it I found my supervisor and owned up to it.  It should be OK and a few people said they not to worry about it but that's pretty hard to do.  The area surrounding the hole is now warped so we have to order a new door and I'll redo it in a week so so, in if I still have my job lol.
<bot>: tried to be a hero and work with minimal supervision, damaged a 5k tool, the steal door panel I was working on and set the company back on completion. FML
