I was REALLY lucky with the gas cyls, I had no way of knowing they would be subject to an avalanche of magnesium. My 75/25 welding gas bottle broke the low side gauge, that's about it. The shelves were `sposed to be rated at 150 lbs per shelf and I had 4 saws per, heaviest saws on the bottom. That's ~1/2 what they were "rated" for. I had 3 saws apart, screws etc in open boxes which I ended up sweeping up. Gonna be fun figuring out which parts went where. I managed to scratch up 3 really clean saws, an XL1 Homey, 041 and 011 Stihl. Broke the plastic on an 025 I'm building for my Dad but that was about the worst of it. Magnesium bounces better than plastic.
The 08 was on a lower shelf and the Mac 15 was on the floor in front of the shelf, they both survived unscathed. I would have been *really* POd if either of those saws got damaged.
First order of business will be properly securing my gas cylinders. Next I'll get off of my lazy azz and fabricate angle iron shelf brackets that I can lag to the concrete wall. Lesson learned, this won't happen again.
