Gentlemen,
At the risk of being handed my head!
I will again bring forward a few facts relating to the Luger Pistol, And Mass Production In General.
Prior to WW-1 The Central European Nations were the first to emerge into the "mechanical Age", and were the first to develop the principals of rudimentary "Quality Control".
Basically the Clock and Musical Instruments Industries followed rapidly by the Arms Industries entered into the Era of Mass Production where very few if any of the critical design parts ever came togather until Final assembly.
The construction of these parts were made possible by the development of the Fixturing and Gauging devices that assured the most precise allignment of the mating parts even when manufactured many miles apart, and even assured the same accuracy when production was renewed after the plants were destroyed by hostile action.
Henry Ford made a study of the European Methods before setting up his assembly lines, and started the beginning of the USA's Industrial Explosion.
Jim Keenan has in his expert way put forth the Best Description of the use of fixtures and Working and Inspection Gaging that I have seen short of the Contract Specifications placed on Industry by NACA/NASA during the beginning of the "Man In Space Program".
The use of Draw Lines/Witness Marks are Nothing New In The Space Industries.
I myself, During My Thirty Six Years at Langley Research Center, have Designed, Manufactured, and Used many of such devices as described by Jim Keenan.
The proper design and use of such devices assures close reproduction and rapid manufacture of Spacecraft Parts even though made in plants separated by Continents and even the Oceans.
I would be so bold as to suggest that His Most Discriptive Post also be preserved as "Typical Production Methodology", (Most Likely Applied in the Manufacturing of the Luger Pistol).
