Revolving-Wheel Ruling Pen
A ruling pen that will do neat work and not leave any ink on the ruler, and which with its small ink fount draws many lines at one filling, can be made from an old discarded revolving-wheel glass cutter. A ¹⁄₈-in. hole is drilled in the body, or handle part, just above the wheel. The hole is filled with a piece of felt—a piece cut from an old felt hat will do—rolled to fit snugly, so that it will bear lightly against the wheel. The felt is soaked with the ink to be used, and the pen is ready for use.—Contributed by Bert Fish, Rochester, N. Y.
¶An excellent method of closing a crack in a wall before papering is to paste a thin strip of linen over the crack. This not only makes a smooth job, but prevents the paper from tearing, should the crack widen.
A Portable Folding Boat
By STANLEY L. SWIFT
A boat that is inexpensive, easily made, and readily transported is shown in the illustration. Since the bow section folds inside of the stern portion, it is important that the dimensions be followed closely. The material used is ⁷⁄₈-in. throughout.
The Construction of the Portable Boat Is Simple. When Folded It may be Transported Readily and may Even be Carried in Three Parts. It Is Inexpensive, and should Prove a Valuable Addition to the Camping Outfit
Make a full-size diagram of the plan to determine the exact sizes of the pieces. Brass screws are best for fastening this type of work, but copperplated nails may be used. Tongued-and-grooved stock is best for the bottom. The joints should not be driven together too firmly, to allow for expansion, and all joints in the boat should be packed with red lead or pitch.
The adjoining ends of the sections should be made at the same time, to insure a satisfactory fit when joined. Braces are fixed into the corners.
Metal straps hold the sections together at the bottom of the hinged joints. These should be fitted so that there is little possibility of their becoming loosened accidentally. The front end of each strip is pivoted in a hole, and the other end is slotted vertically on the lower edge. Their bolts are set firmly into the side of the boat, being held with nuts on both sides of the wood. A wing nut, prevented from coming off by riveting the end of the bolt, holds the slotted end. Sockets for the oars may be cut into hardwood pieces fastened to the gunwales. The construction of the seats is shown in the small sketch at the left.
