My career as a machine designer was always with top management being critical of "over engineering" when I put something into the design to make it wear longer or easier to repair. But when I constantly see on this board the "souping up" of 50 year old tractors and the ridiculous increases in loads the old gears, shafts and bearings can handle, my conclusion is that the old farmers went to the bank to buy machinery that was "over designed". And just to add sour grapes, many of the current day enthusiasts of really old iron never had to make a living with the stuff. Leonard feeling grumpy tonight!
