Of course, you'll need a few tools, here are mine; a jigsaw and a couple of clamps. I also have a folding table that you can see in the next picture.
Check that the saw-blade lines up, both where the blade will start and finish cutting the wood. Make sure that the edge of the blade is on the line, and not the center of the blade. Otherwise your cut will be smaller than you want it to be, as the blade will annihilate the wood in it's path, and then a little bit.
Here are some "pro tips" I've learned while cutting the 24 corners off of the shelves. First the one I knew going in;
|Face the edge you want to look nice downward (on the opposite side as the jigsaw).|
The orbital jigsaw blade moves down, forward, and then up, the amount of forward and back is what gives it the orbital name, and most orbital jigsaws allow you to adjust the amount of forward and back motion. For instance, I usually set mine to cut with a light orbital action on plywood because I want a fairly reasonable finish (our plywood is going towards furniture after all), however, you could set it to a larger reciprocal (back and forth) action for rougher, but faster, cutting along plywood.
I also noticed that the direction of the grain matters. If at all possible, aligning the grain direction with the direction of the jigsaw cut produces a much smoother and nicer cut. It seems when it cuts against the grain, it is more likely to catch and pull up splinters.
Well, that's the cutting of the main pieces of the bedside tables. Next up will be sanding and staining, followed by putting these pieces together.
