Be real careful when you are turning larger bowls and platters on this lathe. It has 16" capacity and the minimum speed is 600 rpm. It even came with 2 HP (???) motor, toolrest extension and pivoting headstock to turn larger outboard. Please resist the temptation to do that.
With 16" at 600 rpm, the speed is 28.57 Miles per hour. That is dangerously fast even for a well balanced piece.
I think that is the same lathe as the Shopfox W1758, I have seen it in action the other night, a bowl demo by a season turner. The lathe was shaking prior to truing up the 12" round bowl blank. Please use the faceplate and tailstock as much as possible and put away the tool rest extension. The toolrest extension on Jet, Harbor Freight lathes are likely to break as well. When it breaks suddenly, you likely lose your balance. That is dangerous.
