For you guys with small shops, I've found a neat addition to your plant that will help immensely with your work. Honest! Sams Club is now selling packages of shock flooring. A package consists of (8) 2' x 2' squares that interlock with each other. Total cost is about $15 a pack. This flooring is like the foam flip-flops you wear at the beach. Very shock absorbent and a dream stand on for long hours. At this price, it's less than PT plywood covering the same area. I've just installed this in all of the walking areas of my shop and it's made a big difference in my fatique level. It also helps with a neuroma I have on one of my feet that is being treated. Now, I can put in those full 12 hour weekend days in the shop and still feel human after.
