1. Determine the approximate compound-rest in-feed for cutting a 1½-12 UNF 2A thread.
2. What is the name for the rotating device that transmits power to the carriage for thread-cutting motion?
3. When threading, what is the reason for feeding the cutting tool at an angle for each depth cut?
4. Name the device used to track the timing of half-nut lever engagement.
5. Why should the depth of cut be reduced for each pass as the thread is cut deeper?
