So when I was doing my fireplace project it was minus 15 outside and with a lot of snow outside. I decided it was a great idea to cut the stones I needed in my shop with a grinder. The cuts went quick and the fit perfect, but now there isn't a corner in my shop that doesn't have stone dust in it. I also mixed concrete in there and managed to get some concrete splatter on my dewalt heater and compressor. The shop truly looks used now, it's going to take a while to clean up the mess.
