Pretty Simple, and cheap. The idea was to improve my accuracy when drilling holes on a material that didn't take pencil markings too well. This may have been covered in an 'ible before- If it has I apologize.
Things you'll need:
Drill- or Drill Press
Step 1: Draw Your Template- to Scale
If you need a larger template, than the paper will allow- draw it to a scale (later, use your printers "enlarge by x" option to enlarge your drawing)
This is a simple template for a series of holes, on a plate.
