Query: The Only Holmes Book

Just got the book this afternoon, not to shabby.From a mechanical engineering designer's line of sight, this book is a nice contrast to his .50 Cal Disaster. Hand drawn doodles are ever present (Holmes has never heard of CAD) and are far from being up to ANSI or ISO standard drafting techniques. As with any quality firearm, you need access to a lathe and preferably a mill. The complete lack of tolerances and poor dimensioning are somewhat concerning. This is the only Holmes book that I might recommend. Acceptable step by step instructions. He does offer mag construction instructions but I would opt for Uzi mags. In order to construct this, one MUST beware of the laws and its consequences. All in all, not a bad read.
