Swing: Manufacturers list the “swing” measurement as twice the center height - what the machine will swing over the bed. The ONEWAY banjo is 1/4″ higher than the Powermatic in front of it, sacrificing 1/2″ of swing (a limitation the author accepts). Still, this is not enough difference to choose one spindle over the other. Small increases in diameter noticeably increase strength.
049″ difference does is to increase the rigidity over 1″ from 2.44 times to 2.85 times, because the stiffness of a round bar increases by a power of four as diameter increases. Converted to decimals, these spindle sizes are 1.250″ and 1.299″ - very close. Therefore, most large lathes use either a 1-1/4″ or a 33 mm spindle (still with eight threads per inch). That is because a 1″ spindle can flex between the headstock bearings with the high forces exerted during heavily laden faceplate work. While this is more than adequate for turning furniture spindles and bowls up to about 12″ in diameter, it is not adequate for heavy faceplate work. Spindle Diameter: All mini and midi lathes have a 1″ spindle with eight threads per inch. The spindle was developed long ago by Delta Machinery Company and has become a de facto industry standard. If you’re in the market for a lathe, let’s look at what else you should be looking for.Ĭhoosing a Lathe: Capacities That Matter A 1″ – 8 tpi spindle is standard for mini and midi lathes. Paying more gets you a tailstock, banjo and tool-rest that lock without undue force being necessary.
For example, very low-cost lathes tend to have levers on the banjo that collide with each other, making adjustment difficult. As you pay more, the machine gets heavier, with friendlier controls. It is fair to note that increases in price usually mean improvements in usability. Lathes come with at least one tool-rest, a drive center, a live center and a faceplate.

While the headstock is fixed at one end of the bed, the tailstock and banjo are free to slide on the ways to suit the turner’s application. Modern lathes have a bed made from cast-iron or welded steel, the top of which sports a set of ways: two parallel strips of constant width and spacing on which the headstock, tailstock and banjo (tool base) are mounted. However, just as dog breeds range from chihuahuas to Newfoundlands but all share an essential “dog”-ness, there are elements that make a lathe a lathe. And full-size lathes can tackle any turning task. Midi lathes are more appropriate for creating furniture spindles and medium bowls. Today, lathes come in three flavors: mini, midi and fullsize, each with strengths and weaknesses that make them more or less appropriate for certain kinds of turning tasks.įor example, mini lathes are great for turning pens, small items and miniatures. Do you want to do mostly spindle turning (creating a cylindrical object)? Or faceplate turning (using a metal disc, the faceplate, to attach wood to your lathe so you can turn an item that can’t be secured simultaneously on the headstock and tailstock)? Will turning be your principal woodworking pastime, or are you buying a lathe to augment your general woodworking? What you need depends on your budget, space and turning goals.
Coyote in the Warner Brothers ‘Road Runner’ cartoons.” They always want a simple answer, like “Buy an Acme Model XJ4, as purchased by Wile E. As the author of several books on woodturning, the designer of a lathe (the Conover Lathe, no longer in production) and a founding board member of the American Association of Woodturners (I’m member #004), it might be an understatement to say that people frequently ask my advice about which lathe to buy or which lathe is the best.
