The mechanic's tool bookWith practical rules and suggestions for use of machinists, iron-workers and others . f a few inches inlength and may be tempered their entire lengthand made reversible, so that either end can beused when needed. When one of these pieces isinserted in the stock, A, a gib, 0, is driven inbehind the piece and securely holds it in place. In Fig. 1G, is given another form of turning tooland stock. It consists of a bar of iron or steelgibs to the tool post and drilled longitunally to re-ceive the stem of the clamp which holds the temp-ered cutting rod. A shoulder is made upon thisclamp which is received in a corresponding recess inthe bar. This serves to keep the clamp and toolsteady. A nut screwed upon the end of the stemserves to tighten up the clamp to the steel cuttingpoint, and consequently to the bearing surface ofthe bar or stock. Now, any apprentice, who LATHE TURNING T30LS. 63 knows enough to take a twist-drill and bore apiece of iron therewith, can make this turningtool. It will receive several sizes and shapes ofsteel rods if necessary, and hold them very Fig. 16. It has the additional advantage that the pointcan be removed for grinding or other purposeswithout removing the stock from the tool post ofthe lathe. Also, no blow severe enough to injuretool or stock need be applied to loosen the pointto permit of its removal. The introduction of lathe tools of the characterabove described indicates mechanical machinists time is too valuable to be em-ployed in forging a great deal of metal to obtaina small turning point, and with his lathe standingidle while he is thus engaged.
