I am very familiar with leaky orings....

Speaking of leaky O'rings screws I was a system's consultant to Raymond Engeering a few years back and I a designed a custom pc (well a pc with real time data acquisition cards) to function as an embedded controller and wrote several tens of thousands of lines of code to create a system, a hydraulic bolting system. You see Raymond had a client that
had a system with several 200 bolt joins and when in past the joint had a loose screw or two, well there was hell to pay. So my system's design created a controlled multi sequence measured and document bolting or screwing process. It was a cool fun rebolting job that paid well. All
because a loose screw let an o-ring leak and kaboom and several died.

Speaking of other screwy problems I also had the opportunity to create another custom interface and database program to allow the Japaneze to know exactly how much load was an each of the thousands of bolts used to hold the suspension cables on the akashi bridge.
