Watch as I share the make for the axels for the tender of the Kozo Hiraoka ¾” scale Pennsylvania A-3 Switcher 0-4-0 steam engine build. In this installment, I will be demonstrating roughing out as well as final machining techniques including facing and plunge cutting, measurement processes using a dial caliper and micrometer. I’ll be demonstrating how I machine the ends that will ride or act as a bearing surface against the walls of the truck journals. An especially important function will be to cut the axels to a specific length. This length is important as it set the gauge or wheel spacing in orientation to the track. At worst poor control here means the tender wheels will damage the track and be a constant source of derailment a source of damage to the locomotive, track, and possible danger to the person operating and those around the operation. All machining is performed on a Sherline 4400 with a self-centering three jaw chuck. I am using titanium nitride coated carbide cutters for the lathe turning processes. If you would like to reference the book, these demonstrations can also be found on pages eleven and twelve.

While modern CNC milling centers are amazing for the maker and home shop machinist, there are some things you simply cannot do without a Lathe. Believe it or not, but the Lathe is known as the mother of all machine tools, for this piece of equipment led to the development of many other machine tools such as the vertical and horizontal milling machines. With proper fixturing, layout, and calculations the Lathe can do it all. It is a keystone piece of equipment in any machine shop whether for commercial or home use. In this video I will be demonstrating the Sherline Lathe “C Package”. I chose this particular Lathe for our project because it had many features, I felt would be beneficial for our build; the Kozo ¾” scale Pennsylvania A-3 Switcher 0-4-0 steam engine. Also, Sherline makes several different conversions that allow their lathe to be used as a mill. Be sure to check it out in the links below. Available from Ebay.
