It’s not exactly what springs to mind when you hear the word “turret,” but Grizzly’s Amazon web store has their MT2 tailstock turret attachment for $55.95. Thought it doesn’t shoot anything or ride atop a battleship, it does rotate tool attachments, which is cool too.
Used in place of a regular drill chuck in your lathe tailstock, the turret attachment allows you to mount up to six tools that can be rotated into place for quick drilling operations. It’s not as beefy as a regular bed turret, but it is handy for the job that drives you crazy with drill chucking.
