re: Wood working question- Update: Finished pics on page 3

Why not make a bunch of cuts flip the beams and finish the cuts? I wouldn't do more than 10 or so at a time.

If you clamp a block to your saw's fence and flip for every cut, every cut will be exactly the same assuming your blade is true and plumb. I'm all about jigs.

If you end up getting a band saw, you will find other uses for it. Like most tools, you don't realize how much you'll use them until you have them but I would stil do the cut, flip, cut in my shop.
