This is the Lumber rack I made. It's based off of one I saw in a Fine Woodworking Article. There is so much weight on it and so far so good. I was nervous putting the lumber on it after I made it but it's doing great and I'm guessing theres around 400 lbs on each tier. Thats just a guess all I know is it is more than I can lift.
Here are my two lathes and they are already getting back in use after about 3 weeks of moving from the other shop.
