How do you square the bottoms of the finger joints? Do you stand the pieces up on end? |

How do you square the bottoms of the finger joints? Do you stand the pieces up on end? I used a 3mm mortising chisel to square things up. There's no room to stand the piece up, my mill* only has 5" or so Z-axis movement. I guess I could program the mill to approximate a 1/8" radius cut on the side of the finger joints, but at the time it wasn't important. I just spent a few bucks on a chisel and got the work done. *I said router before, but it's really a mill.

Or rip a 16' 2-by? |

I Agree. For the sake of argument, I'll take a contrary viewpoint. One of the reasons our shapes tend to be square and based upon squares is that they're easy to make. A circular saw wants to cut straight, it just needs a little help. Jigsaws need care to cut curves nicely and bandsaws usually have limited throat clearance. CNC lets the machine handle fancy and complicated cuts, so it might unlock the creativity of the guy using the machine. Now that he's got a machine that will do perpendicular curved cuts, he'll be more likely to do that fancy cutout and now the desk he's building looks something like the great Chicago Bean. (Maybe it even opens up, like an old roll top.) It's not that he can't do it with traditional tools, it's that the CNC has taken some of the frustration and tedium out of it.
