Firearm Anatomy - Book II The STEN Submachine Gun - Paperback

by David S. Findlay (Author)

This book was written to interest the reader in gun design.The gun industry needs and is due for the next big breakthrough. Every 100 years seems to bring the next big development in firearms technology. In the 1600's the wheel lock was developed and heralded the first use of firearms. In the 1700's came the flintlock musket. In the 1800's came the percussion cap and later in the century the thin brass shell to carry the powder, ball ammunition, and primer was perfected. While the 20th century has seen the invention of liquid propellant, caseless ammunition, and the gyrojet, the thin brass shell has been hard to beat and is still the dominant way to feed ammunition to the firearms of today. We are due for the next big advance, but from where will it come?This book was written to interest the reader on the simplicity and the hidden complexity that good gun designs exhibit and prompt the imagination of the reader to investigate the field of firearms design further. Reading this book will give the reader: -Two ways to calculate the round per minute level of a 9mm caliber submachine gun using the STEN submachine gun as an example and gives sample excel spreadsheets to allow the reader to experiment with different design conditions.-The full technical data package of a reverse engineered STEN Submachine gun. The drawings are shown as individual operation process sheets showing the dimensions for each separate cut on an individual drawing.-The cycle of operations of the STEN with illustrations.-The analysis and sample calculations to design a gun barrel.-A discussion of firearm metallurgy with recommendations on material selection and heat treatment for various components.This book is unique as it is not a picture book of firearms, a combat guide on how to use them, nor discusses their maintenance or care. It does expose the engineering that can go behind a gun design project. This book not only gives the reader the drawings for a gun but also explains the engineering and dynamics behind it.

Author Biography

The author, David Findlay, has spent his entire life around firearms and in the field of gun design. The author first worked for 26 years at Remington Arms as a designer and in middle management in charge of other gun designers and firearms acceptance testing. He then worked four years for Marlin Firearms/H&R 1871 as a product engineer and later in charge of the engineering group at H&R 1871. Currently he is employed by Smith & Wesson as a product engineer. David's experience has included working on the following Remington product lines; M/870, M/1100, M/1187, M/522 Viper, M/700, and SP-10 Magnum. While at H&R 1871, David was involved in improving product quality, product performance, and new line extensions of both their rifle and shotgun single shot product lines. Now at Smith & Wesson, David has worked on the M&P 4 full auto, the M&P 15 semi-auto long gun lines, and has also worked on the Thompson Center product lines as a product engineer. Along the way, the author has received eight patents: #5,373,775Disconnector in Two Planes #5,442,874Firearm Mag Box Alignment #5,448,939Firearm with Multiple Sears #5,551,180Releasable Bolt Lock #6,240,670Firing Pin Lock #6,256,917Firearm with Lockable Safety #8,261,652 Ambidextrous Bolt Stop #8,418,803 Flash Suppressor This is David Findlay's second book.
