For microgroove recordings(16-2/3, 33-1/3 and 45 rpm), the recommended cutting stylus tip radius is. 00025 inch or less, and for coarse groove recordings(33-1/3 rpm transcriptions and 78 rpm) the recommended radius is. 0015 inch. You can see why a 78 played with an LP stylus sounds so bad! For coarse groove recording, the stylus was often mounted with a slight mechanical bias toward the center of the record. This ensured the thread of cut lacquer material or "chip" would be thrown toward the center of the disc thus avoiding fouling the stylus tip. 2, record 8, English, - chip

The unified thread form accompanied by the unified thread standards has in the past fulfilled the necessary requirements for interchangeability of threaded products between the United States, Great Britain, and Canada. This modified thread form represented two compromises between British Whitworth and United Stated National thread forms. The British accepted the 60° thread angle of the American thread, and the Americans accepted a rounded root and crest similar to the Whitworth form. The United States National unified form for external threads has a rounded root and may have either a rounded or flat crest. The unified thread contours provide advantages over both the earlier forms ....

Unified and American National screw thread standards for screws, bolts, nuts, and other threaded parts consist of six series of threads and a selection of special threads that cover nonstandard combinations of diameter and pitch. In general, the unified screw threads are limited to three series : coarse(UNC), fine(UNF), and extrafine(UNEF). A 1/4-inch-diameter thread in the UNC series has 20 threads/in., while in the UNF series it has 28. In the Unified and American National standards, the coarse thread series(UNC and NC) is recommended for general industrial use on threaded machine parts and for screws and bolts. Because a coarse thread has fewer threads per inch than a fine thread of the same diameter, the helix angle is greater, and the thread travels farther in one turn. A coarse thread is preferred when rapidity and ease of assembly are desired, and where strength and clamping power are not of prime importance. 3, record 14, English, - American%20National%20Coarse%20Thread

The manufacturing tolerance and allowance permitted distinguishes one class of thread from another under the unified thread system. Because allowance is an intentional difference between correlated size dimensions of mating threads, and tolerance is the difference between limits of size, a thread class may be considered to control the looseness or tightness between mating threaded parts. The American National standard for unified and National screw threads provides classes 1A, 2A and 3A for external threads, classes 1B, 2B and 3B for internal threads, and classes 2 and 3 for both internal and external threads. Classes 1A and 2B are for ordnance and other special uses. Classes 2A and 2B are the recognized standards for the bulk of screw-thread work and for the normal production of threads on screws, bolts, and nuts. Classes 3A and 3B are for applications where smaller tolerances than those afforded by 2A and 2B are justified .... 2, record 15, English, - thread%20class

Threads are designated by standardized notes. Under the unified system, threads are specified by giving in order the nominal diameter, number of threads per inch, the initial letters such as UNC or UNF that identify the series, and class of thread(1A, 2A, and 3A or 1B, 2B and 3B). Threads are considered to be right-hand and single unless otherwise noted; therefore the specification for a left-hand thread must have the letters LH included. 2, record 15, English, - thread%20class

Unified and American National screw thread standards for screws, bolts, nuts, and other threaded parts consist of six series of threads and selection of special threads that cover nonstandard combinations of diameter and pitch. In general, the unified screw threads are limited to three series : coarse(UNC), fine(UNF), and extrafine(UNEF). A 1/4-inch.-diameter thread in the UNC series has 20 threads/in., while in the UNF series it has 28.

In general, the unified screw threads are limited to three series : coarse(UNC), fine(UNF), and extrafine(UNEF). A 1/4-inch.-diameter thread in the UNC series has 20 threads/in., while in the UNF series it has 28.... The fine thread series(UNF and NF) is recommended for general use in the automotive and air craft fields for threads subject to strong vibration. In general, a fine thread should be used only where close adjustment, extra strength, or increased resistance to loosening is a factor. 3, record 17, English, - Unified%20National%20Fine%20screw%20thread
