A blacksmith would take a flat piece of iron and beat it into a cylindrical shape around a mandrel -- a long rod of the proper diameter. By heating the iron to a high enough temperature in a forge, the blacksmith actually welded the seam along the length of the barrel to form a ...

When the piece has been previously reamed or bored, it may be pressed upon a mandrel and then mounted between the centers. Two types of mandrels may be used for mounting workpieces between centers. The solid mandrel is satisfactory for many operations, while one having a shank tapered to ...
Work coils are of numerous types ranging from complex to simple. The helical wound (or solenoid) coil is an example of simple coil, which consists of many turns of copper tube wound around a mandrel. A coil precision-machined from solid copper and brazed together is an example of complex ...
if a machine with a mandrel would not work for the particular bend, we packed the pipe with sand, heated it with a oxy/acetylene torch and bent it. bending was actually the prefered method for a ship. the bends allowed the piped to come and go as the ship tossed and turned. ...
