It is almost impossible for us to give you an idea of how much you could save by eliminating grinding, because in the first place we don't know how much your box costs you, and, secondly, you may be paying a much higher price than we do for grinding. In view, however, of the probable cost of your box, and of the fact that you should be able to grind all the gears in any box for under £1, you would not be likely to save more than a very small percentage of the total cost by changing over to shaving, which requires expensive tackle, to be paid for, in your case, by a small number of boxes. "All this is very vague, but I fail to see how it can be anything else under the circumstances. I feel quite certain, however, that you will be well-advised to stick to grinding, assuming that you are not paying a fantastic charge for it." Rm.{William Robotham - Chief Engineer} | ||
