The layout tools (see Figurę 1) in-clude: a 6” or larger dial or digital caliper; a micrometer; a 6” machinisfs rule; a 4” ma-chinisfs sąuare; a scribe; a center punch; a four- to six-ounce machinisfs ballpeen hammer; both a 4” and a 6” divider; plus

Dykem or similar machinisfs layout fluid. Finally, you’ll need a magnifying glass or Optivisor to make certain your layout lines and center punch points are precisely lo-cated.

It is also very helpful to have a Dremel or Foredom hand grinder. While a lathe or milling machinę is not necessary, they can save time. However, there are darń few parts that cannot be madę with simple hand tools, given enough time and determination on the part of the gunsmith!
