The term "capstan lathe" overlaps in sense with the term "turret lathe" to a large extent. In many times and places, it has been understood to be synonymous with "turret lathe". In other times and places it has been held in technical contradistinction to "turret lathe", with the difference being in whether the turret's slide is fixed to the bed ...
Capstan winches were also important on sailing trawlers (e.g. Brixham trawlers) as a means for fetching in the nets after the trawl. When they became available, steam powered capstan winches offered a great saving in effort. These used a compact combined steam engine and boiler below decks that drove the winch from below via a shaft.

A full-sized human-powered capstan is a waist-high cylindrical machine, operated by a number of hands who each insert a horizontal capstan bar in holes in the capstan and walk in a circle. captain 1.
(The latter is due to the toolpath being controlled by the machine, either in jig-like fashion via the mechanical limits placed on it by the turret's slide and stops, or via computer-directed servo mechanisms on CNC lathes.) [5] There is a tremendous variety of turret lathe and capstan lathe designs, reflecting the variety of work that they do.
The T-34 medium tank is one of the most-produced and longest-lived tanks of all time.. Identification of T-34 variants can be complicated. Turret castings, superficial details, and equipment differed between factories; new features were added in the middle of production runs, or retrofitted to older tanks; damaged tanks were rebuilt, sometimes with the addition of newer-model equipment and ...
A powered capstan, also called a winch, rotates so that the applied tension is multiplied by the friction between rope and capstan. On a tall ship a holding capstan and a powered capstan are used in tandem so that a small force can be used to raise a heavy sail and then the rope can be easily removed from the powered capstan and tied off.
