[Healeys] torque wrench

[Mike]

Brings to mind two experiences.  When I worked in aircraft, fasteners 
were as small as possible, as weight was a primary concern.  When I 
worked for a heavy machinery manufacturer, we learned the hard way that 
some mechanics used the "as tight as I can" method.  As a result, we 
never used less than 3/8 inch bolts, even if less would do.  They would 
torque the heads right off of anything less.  Also, since the equipment 
was used in 24/7 continuous process systems, one component out of 
commission could shut down the entire line.  Accountants don't like that.
