Making an Umbrella Handle Detachable
A parasol or umbrella with a detachable handle is a great convenience in packing when traveling, and a handle may be made detachable as follows: Remove the handle by using a block of wood and a hammer. Clean out the hole, and polish the steel stem with emery, as far as it goes into the handle. Cut off 1 in. from the end, and then solder a section of brass tubing into this piece, and another section into the end of the stem. The abutting ends are then tapped to fit an 8-32 screw, which is then soldered into the shorter piece, as shown. The latter is pushed into the handle, and a hole, ¹⁄₁₆ in. in diameter, is drilled almost through the handle. A piece of wire nail is driven into this hole. By making the screw fast in the handle rather than in the stem, the threads are protected, and the length when taken apart is correspondingly reduced.—John D. Adams, Phoenix, Ariz.
