	Our lathe is manufactured by [http://www.siegind.com/product_detail/sc2-mini-lathe-15008601238810425.html Sieg Industrial Group]. It was sold in the United States by [https://www.micromark.com/MicroLux-7x16-Mini-Lathe MicroMark]. [http://micromark.com/Instructions/84631lathe.pdf The operating manual is available here]. Be aware that our lathe has metric lead screws, whereas MicroMark advertised their lathe as having inch lead screws. [http://micromark.com/Instructions/84631-lathe-assembly.pdf The assembly manual is here].

	Our lathe has a 75 mm spindle face and Morse Taper 3 spindle taper with a 20 mm through hole. We have a 3 jaw chuck, a 4 jaw chuck, and an ER32 collet chuck. Other chucks and adapter plates are available from [https://littlemachineshop.com/products/products.php?category=566826475 LittleMachineShop.com].

	The dials on the lathe are in metric. The cross-slide moves 1 mm for every full rotation of the hand wheel. With 50 dial divisions, this means that each division is 0.02 mm of radial distance from the center of the spindle. When removing material it is often useful to be thinking in terms of diameters rather than radiuses; the lathe is therefore marked 0.04 mm of diameter per dial division.

	The lathe is equipped with a [https://littlemachineshop.com/products/product_view.php?ProductID=3112&category= Tormach 0XA quick change tool post]. This allows the removal and installation of cutting tools without changing the height of the tool with respect to the centerline of the spindle axis. These tool holders are available inexpensively [https://littlemachineshop.com/products/product_category.php?category=1005208204 from LittleMachineShop.com] and also [https://amzn.com/B01N6BABTD on Amazon], [https://www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=30705&portrelay=1 from Tormach], [https://is.gd/9jLuRd from HHIP], and a lot of other vendors. You're looking for 0XA-series tool holders.

	These tool holders are appropriate for 6 mm and 8 mm tools or 1/4" and 3/8" tools. These are available [https://www.harborfreight.com/5-piece-indexable-carbide-tool-set-39931.html from Harbor Freight], [https://littlemachineshop.com/products/product_view.php?ProductID=1669&category=1208242246 from LittleMachineShop.com], and many other vendors.
