Funny thing is, thats why I never were gloves or long sleeves.
One day I used a right angle grinder on my truck rear cab mounts, they had broke through from jumping the truck.
I saw the speaker wire and ignored it. Suddenly the wheel grabbed it at 10,000RPM's, broke it off and weed whacked my private part 50 times in a second, then I dropped it and the grinder flopped around like a fish until I unplugged it. It had a maintained on/off switch, not momentary which is what I use now.
I honestly thought I had been, well, sex changed. Purple/yellow/black and blue for 3 weeks. I learned a valuable lesson that day!
Glad your bud is OK, I like a big red E-Stop right where I can nail it in an emergency...........
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
