I was looking for a benchtop lathe with a little more grunt and capability than the smaller, hobby-type machines, and without spending a ton of money. The lathe arrived well crated and covered with preservative. Plan on using up a roll of paper towels getting this stuff off. Once mounted on my workbench, I checked the spindle for runout with a coax indicator and also checked the tailstock alignment. Both were on the money. I obtained a live center, drill chuck, and a set of tool holders locally, and was off and running. First project was a steering tube for an outboard motor, that required a 12" length of aluminum stock to be turned to 7/8" OD and a 14-TPI thread cut. Both operations went extrememly well. Vibration is very low and this machine is solid.Some gripes: When cutting threads coarser than 14 TPI, the end gearing arrangement prevents the access cover from being closed. This I see as a potential safety issue. I would like to see a power cross feed added, even if it added to the cost of the machine. Finally, I would like to see the inside of the tailstock taper keyed for the drill-chuck arbor.
All said, this is a lot of lathe for the money. I see from other reviews that some people aren't happy, but my experience has been positive so far. I've done this stuff for a living on a $20,000 toolroom lathe and this little JET does many things just as well. It is a small machine with limited power, but should serve most home machinists very well when used within its limitations.
