Mechanics for young America; how to build boats, water motors, wind mills, searchlight, electric burglar alarm, ice boat ..etc.; the directions are plain and completeReprinted from Popular mechanics . l shape. There is apin R set into the base board of the ovalform and the strip of metal for bending isgrasped at S and the other end is insertedback of the pin R. By applying pressure,the strip of metal is bent to the form. Fig. 9 shows the hour-glass wood bend-ing form, made by selecting a piece of hardwood block, about 6 inches square andboring through with an inch bit. Then thehole is shaped hour-glass like. The view isa sectional one. The block is placed in avise and the strip for bending is insertedas at T. The strip of metal is grasped at W andcan be bent to various forms by exertingpressure. Fig. 10 is another type of fire-place front, constructed by uniting theshaped metal pieces. In fact an almostendless variety of designs can be wroughtout after the start is once made. A goodway to figure the price on the grate is toadd up the costs of the parts and chargeabout 12 cents per hour for the work.
