The burnisher helps to keep the metaltrue as it folds round it while being drawnthrough the hole. The rough tube whichresults from this operation is annealed anddrawn through the next smaller hole, andso on until the desired size is attained. The student will find this very usefulin the preparation of tubing required forhinges of brooches, lockets, boxes, andcaskets. If the tube is not large indiameter all the work can be done in thevise and without a draw-bench. Hollow tubes of any section can bedrawn by using draw-plates with holes ofthe required section, or the student can 42. jpousse Fig. 5. 43 Wire- .. make his own draw-plate out of an oldDrawirving flat file, first softening it, then punchinggraduated holes with a taper punch of therequired section filed up out of bar steeland properly hardened. The taper mustbe very slight or the edge of the hole willbe too sharp, and will strip the metal in-stead of compressing it. There are very few things necessary inthe workshop which a student can not makefor himself. The curse of modern work-shops is the dependence of the workmen onmachine-made things. Rather than meltan ingot and roll a small piece of metal forhimself to the exact size he needs, he cuts astrip from a sheet in stock which is nearestto the size. The effect on the work is de-plorable. The chief beauty—the qualitygiven by human handiwork—is absent, andnothing can make up for the loss.
