7 INSTALLING BALL STANCHIONS Kenneth L. Fairbanks O Since brass rail stanchions are more often used on the upper decks where the wood is thin the problem of securing these tiny fittings is usually a vexing one.Even on the lower, and more substantial decks, especially those with pronounced sheer there is a tendency towards lifting, on the part of the stanchions which are the lowest, when the wire rails are set tight. By turning a thread on the stanchion, where it penetrates the wood, greatly increased rigidity may be obtained. All that is needed is model-builders' tap and die set, size 00. This set is manufactured by Woodruff and Stroks Co., Hingham, Mass., and can be obtained by any good hobby store. It contains four taps and dies, sizes 00-90, 00-80, 1-72, 2-58 die holders, tap holders, and an Allen wench. There is a size table on the inside of the box in which they are packed, that gives the tap and die hole size, O.D. size of screw, and the drill size. The stanchions should be more or less the same size, O.D., on the part to be threaded as this will govern the threads you will cut with the die. For instance, l/8"-scale stanchions will be .O^l on the O.D. This should not vary more than two or three thousandths(plus or minus). This so the die will cut a full thread but will not have to remove too much stock. By placing the stanchion in the proper hole in the die and holding it in the left hand, you can, with the die, in the die holder, in the right hand easily cut the thread.The thread should be run up to the shoulder on the stanchion,as closely as possible, so it will tighten down on the deck. A drop of glue, preferably pliobond, should be applied to the thread before screwing down into a thin deck to give added support. By using a drill about .010 smaller than the threaded stanchion the threads will engage the wood of the deck and give at least 75% of their maximum holding capacity. J. W. WESTCOTT From P.6 Detroit Chapter of the Michigan Society for Crippled Children; the Masons; the Propeller Club; Detroit Rotary Club; and others. Born in Detroit, December 22 1883, his entire life was spent in the company which his father founded in 1873 to expedite Great Lakes shipping, and which he headed at the time of his death. ______________________________ MUSEUM NOTES The year 1958 started with a bang, as far as new materials goes. By the middle of February the following items had been accessioned: 1 Scale model, "Pere Marquette 18," a Lake Michigan R.R. car ferry, a gift of the Chesapeake & Ohio R.R. Co. J. Kermath marine motor, (1919) from David Underwood of Ann Arbor. 1 Machine for demonstrating the link type of steam valve operation, from Frank J. Slyker, East Detroit. 1 Watercolor, 2 lithographs, and 5 oil paintings of Great Lakes vessels of the past, from the Estate of Mr. George Kolowich. These were formerly on loan to the museum.
