The only two advantages of the outmoded, incoherent, non-metric systems is that (1) the kids might learn their 'times tables' better to cope with a system which is out of step with the rest of the world, (they now use a calculator for everything except their ten X table), and (2) 4x3 boxes (dozens) are easier to handle than 5x2 metric boxes. It is perhaps peculiar for you to relate air pressure to that of the atmosphere. It just so happens that one Bar in metric is virtually one Atmosphere in air pressure. So simple, really. You might be able to remember how to convert if you know how many psi there are in one atmosphere or the psi value of a vacuum. It's easy for metric users - it's ONE!!!! Unit. We needn't go into Pascals here, except of course that it is defined as 1 Newton per 1 metre square, a rather small unit (about 4 ounces per 11 square feet?!)so there are about 100 thousand in one Bar but it is so easy to put in the relevant number of 'powers ten' kilo, mega, giga, tera, exo, deci, milli, micro, nano - the same as in all the metric units. One further point - do you get billed for your electricity in kiloWatt hours or still in British Thermal Units (or some other antiquated unit)? Just wondered. You may be more metricated than you thought. Btw - you should not be decrying your largest and closest trading partner, who are sensibly fully metric (except for weight units). Regards, RAB

In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
