Chapel Perilous has taken its toll on me and indeed, my cosmic trigger finger is broken. For readers not familiar with Chapel Perilous I will give Robert Anton Wilson's definition of that god forsaken place.

Keep wood chisels razor sharp for building cabinet doors. A good set of chisels helps clean up and fine tune mortises and tenons or remove a bit of wood anywhere you need to, such as the ends of panel grooves in door frames. A chisel set and mallet are essential woodworking tools.
Hinges attach the cabinet door to the frame. The number of hinges you need depends on the height and weight of the door. Use two hinges for doors less than 40 inches high and less than 11 pounds. Use three hinges for doors 40-60 inches high and 13-20 pounds. Use four hinges for doors 60-80 inches high and 29-33 pounds.
