I glued up 1x8s for a 4' round table top. I didn't have enough long clamps, my radial arm saw was off, (I've since adjusted it), and yes, I wasn't patient enough. As a result, I wound up with a warped table top. I thought I'd try to use pocket screws and glue on my second try with 1x6s. What are the pros and cons of using pocket screws? Any help would be greatly appreciated?
