What is the approximate of your Mitchell lathe (e.g., 6.5-inch, 8.5-inch, or larger)? If you are interested in exploring other historical
Active primarily in the latter half of the 19th century, Mitchell & Co. specialized in the production of machine tools, with a particular emphasis on lathes. This paper argues that Mitchell’s "lathe work" was not merely functional manufacturing but was instrumental in solving the specific engineering challenges of the worsted spinning industry. By analyzing patent records and surviving engineering specifications, we can trace the evolution of Mitchell’s lathes from simple turning machines to complex, specialized tools capable of high-precision mass production.

If you are cutting metric threads on an Imperial Mitchell lathe, you must use the appropriate 127-tooth transposing gear in the end train. Crucially, when cutting metric threads on an Imperial machine, never disengage the half-nuts at the end of the cut. Instead, back the tool out and reverse the entire spindle motor to return to the start point. Facing and Boring Long Workpieces
Mitchell lathes are equipped with a comprehensive quick-change gearbox for screwcutting and feeds. By shifting a combination of levers, operators can instantly select dozens of different Imperial (TPI) threads and longitudinal/cross feed rates without manually swapping loose change-gears, though extra gears were often supplied for cutting metric threads. 2.
