[Milsurplus] Sic Transit Gloria Motrac

[Mike Feher]

Almost my entire engineering career was for the military. Have you ever seen a hammer test on equipment? The largest one I have ever seen was at, as I recall, NAS Indianapolis. There they had a very large, explosion driven projectile designed to hit the gear. Sadly, I never saw that one in action. However, some of the hammer test that I witnessed did create some interesting and unexpected results. 73 – Mike

Group,

 

My first job out of the US Army in 1968 was with Motorola in Schaumburg. I was a tech on the Motrac line and my job was to power up the freshly assembled units and make sure each one worked to spec. The last test was to put the unit on a dummy load with a Bird 43 wattmeter, key the mike and then beat on it with a rubber mallet, looking for any power output change that would signal a problem, perhaps an intermittent connection. Needless to say I enjoyed that part of the test. I've never had another job in electronics where a good hammering on the product was encouraged.

 

I miss those days.

 

73,

Dave
