I'm in the middle of my first real build, besides a couple of birdhouses. It's a version of the Flip Console Table (http://ana-white.com/2012/05/plans/stair-leg-flip-top-console-table), modified a bit to fit the dimensions of where I want to put it.
So far so good, I guess, but I'm having a heck of a time staying square. I'm building it with regular old pine from the local lumberyard, and the trouble is that I can't keep square because, well, the wood's not square! There are cups and warps—nothing major, but enough to put it out of square in a few places. I selected the straightest wood that I could, but I'm still running into problems. My reading tells me that a planer and a jointer can help a lot, but I don't have those things in my workshop. All I have is a table saw, a drill, and a kreg jig.
I've been using the table saw as a jointer which helps a bit but can't eliminate cupping or warping.
Looking at the brag board, I sometimes get the impression that I'm the only person with these frustrations! How do you all do it without a fully kitted out workshop?
