Figure 2-4. A bandsaw or scroll saw can be useful for cutting ninety degree corners.
If you examine the building plans, you'll notice that parts cut do not have curves and angles; all cuts
are right angle cuts. Some of those cuts (like the one seen in Figure 2-3) can be a bit tricky, and that's
where a bandsaw comes in. Its small blade can get into corners and handle notches. But even a
bandsaw or scroll saw has limits: because of the way the blade cuts and how you feed the piece into the
blade, you'll be forced to curve the piece as the blade moves toward a corner. This will result in a small
curve instead of a sharp ninety degree corner. If you look at the building plans in Figure 2-5, you can see
that the notch has a crisp ninety degree corner.
