And as al-most every blacksmith would like to know how, I willgive the process. When making mill picks use steel ofmedium high carbon, say 90 points, as mill picks requireharder steel than ordinary tools, as they have to cutvery hard material, while the blows are very light. There are different sizes of mill picks which depend 78 THE TWENTIETH CENTURY on the miller who is going to use them, ranging inweight from 2 to 4 pounds, but the medium-sized pickof about 3 pounds weight is most used. There are alsoditTerent styles of mill picks, some have an eye punchedin them for a handle, while others are made to fit in asocket. The main object, however, is to have a millpick drawn out thin and hardened properly, in orderto do a great amount of cutting and hold a good cut-ting edge, without being ground often or having thecorners continually breaking off, which is dangerous tothe millers hands and eyes. Now supposing some picks are to be dressed. The. Fig. 27. Correct shape of mill pick. first thing to do is to draw the hardness by heating oneend to a low red, before dressing the other end, other-wise there will be a tendency of the end held in thetongs to break off, when dressing the opposite end, un-less the picks are very thick. Heat the end to bedressed or drawn out, to a deep yellow heat (so that thesteel will be worked clear through, thus leaving nostrains which would afterwards cause cracks), draw itout thin to 3-16 of an inch thick on the cutting edge,tapering to % of an inch thick, V/o inch back, at thesame time having the cutting edge barely as wide as TOOLSMITH AND STEELWORKER 79 the body of the mill p
