You've been given some good advice by Bubba, Bruce, and Piper_chuck. One thing I will add is about the Slot Machine. You can do without it, but if you don't have on do not use a cut off wheel on a Dremel to cut your slots. The cut off wheel is too thick and makes your slot too large for the CA Hinges. If you have to cut the slots by hand, cut them with a #11 x-acto blade. Now with that said, get the Slot Machine. It's well worth the money you'll spend on it. As said above, practice on some scrap first before you cu the real thing.
