About the time my son started working with me we made three tables the same size. First one took about an hour as we 'learned' the tool. Next two took about 20 minutes each/ Now, I write down the dimension and we adjust the cuts to match what we want. Your 'face' frames cross brace is 7" shorter than the outside dimension of the base, and the board attaching the 2 face frames to each other are 3" shorter than the length of the base.
We have found that making a base that is a few inches smaller than your 'table top' stops you from stubbing your toes, so we do them all that way now.

Please, any of the 'old timers' are happy to see old threads are still useful, post away. I think I only have about 12 total threads, so it won't take long. I do check this forum at least once a day.
