I mean wobbling from left to right. See I didn't even know that was called racking. I've built a handful of things from her site and everything seems to be fine and holding. This bench the only reason I'm concerned about the moving is my father in law is quite overweight and I want to make sure it's secure. Otherwise there really isn't much racking. Thanks for the advice though about websites. Is there another site that has good diy plans on it?
