This almost sounds crazy to me if it hadn't occurred...has anyone had any problems with the degree scale on a Jet 1340 lathe? I was threading a barrel for the first time and halfway through the depth I realized a rampart thread thred was developing. Needless to say, I had to cut and start over. Before I did I rechecked everything. Although the tool post was set at 29-1/2 degrees it just didn't seem right so I applied a seperate protractor to measure it. It was Waaaay off! Set the toolpost with the seperate protractor and cut a good thread. Has anyone heard of this happening to anyone else or was it just a fluke in production?
