HA! You think that till you wake the entire neighborhood up cutting those off and grinding things down. You are about to create some of the loudest noise there is in a shop. She will then be mad as hell with two kids that cannot sleep cause they want to know what dad is doing in the garage.
I’m no stranger to the grinder, neither are my neighbors, this I assure you. I’ve used that HF one I have more times than I can count, sometimes for hours at a time.
I always do it at an appropriate time when no one is in bed. The welding is what I would save for later at night.
