In the case of line shafting for manufactories, if the speed varies so much from that of the first movers on machines as to require one or more intermediate or countershafts, the expense would be very great; on the contrary, if countershafts can be avoided, there is a great saving of belts, bearings, machinery, and obstruction. The practical limit of speed for line shafts is in a great measure dependent upon the nature of the bearings, a subject that will be treated of in another place.(1.) What causes tools to bend or break in hardening?(2.) What means can be employed to prevent injury to tools in hardening?(3.) Can the shades of temper be produced on a piece of steel without hardening?(4.) What forms a limit of hardness for cutting tools?(5.) What are the objects of steel-laying tools instead of making them of solid steel?
