Here is another shot of one of our lathes. It is a pretty big HL-30. We can spin around 30 inches on it I think--never had a reason to try something that big, however. We use big lathes because you have to have the power to hog on the nasty materials we use like 4340 and 17-4 stainless. It is a 30 horsepower lathe. For reference, home lathes are 1-5 hp. Most manual lathes in machine shops are 2-5 hp. Of course, there are lathes out there to turn battle ship barrels...who knows how many hp they have!
