Anyone here know woodworking?

I would rather get the exercise too. I looked at the combination plan and some Veritas stuff. Then I looked at a sliding miter saw and that may be what I need, since I want to make half lap joints. Is there was a hand tool that could do those?

I would do like Mattax says and to add to that a router plane would also clean it up nicely.

I will say that the value of extremely sharp and perfectly flat chisels and plane blades cannot be overstated. Especially when working cross grain.
