Shop safety tip of the day, or the golden horseshoe award. For 12 years I've had a tire filler chucked into the hose reel on the 2 post lift. I also usually have the windows up in the cars, but was airing the Bird out after running the ozinator in it. Fired up the air compressor today and just after it had shut off I heard an air leak and then a pop. No dents in cars, but the threaded in portion shot in through the passenger window of the Bird, out the drivers side and across the floor under the Bee!
