Figs. 67, 72, and 73 show the arrangement of the interior of the shop. Near the door and against the window is a work-bench with shelves, boxes, and tool-racks. This end of the room is called The Machine-shop, for here are the metal working-tools, wire springs, locks, bolts, nuts and all the odds and ends that are useful for mending anything, from a bicycle to an umbrella. Under the six-foot window is the carpenter’s bench for carpenter-work. In Fig. 72 there is a Tool-rack across the front of the window for files, chisels, etc., but this is only a place to thrust the tools you happen to be using at the time. On account of the danger of rain from the open window, tools should not be left in the rack after the work is finished. In place of drawers, wooden boxes are made to fit loosely into compartments prepared for them. These boxes have wooden handles, as shown in the diagram, and they will be found very convenient. There is plenty of room under this work-table for more boxes when the accumulation of materials renders additional storing-room necessary. Sets of deep pigeon holes are very convenient for extra bicycle spokes and similar objects. Fig. 73 shows The Carpenter’s Bench, and a few tools stored on the wall. A board with holes bored in it makes a good rack for hammers; saws should always hang in an accessible place, and ordinary brass or iron hooks may be used for this purpose. [Illustration: FIG. 74.--A Box.] To Protect your Auger-bits from danger of rust, tack a piece of thick cloth or soft piece of leather to the wall, using sufficient material to allow a flap to hang down and cover the bits. Under the flap is a number of pockets, divided by stitching the front to the back-piece, or by tacking the division lines to the walls. (See the left-hand upper corner of Fig. 73.) Care of Shavings. A barrel or large box or basket should always be near the carpenter’s bench to receive the shavings, and the stove must be set in a box of sand or earth, to prevent any danger of hot coals falling amid the easily ignited materials in the carpenter-shop. (Fig. 68.) The hole in the roof, where the stove-pipe goes through, must be protected by a sheet-iron ring or collar. A Place for Tool-racks. The blank wall, opposite the carpenter’s bench, may be covered with tool-racks, shelves, and other arrangements for the convenience of the young workmen. To Keep Small Things. A number of old square tin boxes, such as certain firms use for packing cocoa, mustard, and various other food material, may be utilized by simply cutting off three sides, as shown in Fig. 74, and making a shelf with a depression for them to fit into, as shown in the sketch. This makes a most convenient nest of boxes for screws, staples, and similar objects. Each box may be lifted out of the rack by its long back and set where it is handy, until you are through with it; then it may be replaced in exactly the same spot, without trouble or annoyance.
