Top triple-clamps on the cheap?

The subject of torquing fasteners has been kicked around frequently here at my workplace lately. We have 20(2 mil.$/each) high speed centrifuges built somewhere around Philly that are mechanical marvels.  Unfortunately the old mechanic who services them thinks torquing is Voodoo and unnecessary. Needless to say he suffer frequent failures due to loose/damaged fasteners.

A recent demo with a bench readout, torque teaching aid showed me just how critical torque is: An overtightened bolt can never be reliably torqued again, lubricating threads,adding washers all greatly effect how much torque is required. Even a bolt that has been correctly torqued previously will lose up to 30% of it's holding strength on reuse.


...snip.  How some even attempt to work on their bikes w/o 
one never ceases to amaze me.  That's MY LIFE on the line when I hop back on 
a mc that's been self-repaired or self-maintained.
