Hello again folks! This week I decided to work on my new Grizzly G0602 - 10 x 22 metal lathe which I just go a few weeks ago. The lathe itself is a very robust machine having the capability to cut 33 inch threads and 26 metric threads. The lathe has a 1-horsepower motor which is coupled to a 6-speed belt transmission that can produce 150 to 2400 RPM. This machine has a lot of features and yet is a simple machine compared to a toolroom class lathe. Basically all of the features a hobby machinist would normally want.
I have done some cutting with this lathe and I am impressed with the accuracy and sheer power of the unit although I am coming from a limited previous machining experience. The machine I am used to is a 7 x 10 mini lathe so anything larger is an upgrade. Although there are a couple of features that my little lathe has that the G0602 does not and one of them is a reversing tumbler for the lead screw.
A reverse tumbler is a set of gears in the drivetrain of the lead screw gearbox that allows the operator to change the direction that the lead screw pulls the carriage during forward rotation of the spindle. Normally a lathe will pull the carriage toward the headstock during forward spindle rotation which allows the operator to use a “right-hand” (from right to left) tool bit to turn down the workpiece. When the lead screw is reversed you are able to cut the opposite direction away from the headstock using “left-hand” cutting tool bits.
The other handy feature of a tumbler is the ability to cut left-hand threads. Although left-hand threads are not commonly used they are still useful in certain applications. A reversing lead screw is a must to cut these types of threads and the G0602 does not have the ability unfortunately.
