You might want to try getting some basswood to use. Most hobby shops have it. You can get a blank wall plaque (8" X 10" X 3/4 " thick) and draw out your patterns. As said before, you need to make sure your drill bit is sharp. I usually always start out drilling the pilot hole with a small diameter bit. Then go back and use a larger bit. I sometimes use three different size bits if I am drilling into narrow pieces (to avoid splitting). Also as said before, make sure your wood grain runs horizontal and straight. A good sharp drill bit will almost pull itself through the wood. Keep reading these posts. There are many talented builders that post. I have learned many lessons.
