The Leg Vice is for heavy duty work, being manufactured from wrought iron or mild steel, with cast steel jaw pieces. It is often used during forge work. The long ‘tommy bar’, allows for forceful leverage. The vice is used for hot and cold forming of metal. It is ideal for holding long pieces of steel, because the jaws are well away from the bench / stand and relatively high from the ground.

They are used when an engineers vice would be damaged, by the nature of the work being carried out. They are often found with their own ‘tripod stand’ or they are occasionally seen bolted down, on a stout workbench. The single leg is sometimes ‘set’ into the ground, in it’s own steel collar, giving it extra support.

With the exception of one position, the jaws are not parallel to each other, because of the way the front jaw rotates around the hinge bolt. There are times when this makes it difficult to secure the work. The jaws of an engineers vice are always parallel to each other.

 
 
 
 
 
 
The leg vice is use here, to hold a substantial piece of steel, ready for forming a 90 degree angle. The steel has been heated to ‘red heat’, on a brazing hearth or in a forge, so that it is malleable and can be formed more easily. The long piece of steel fits between the jaws of the leg vice, without interference from the bench, giving plenty of room. The heavy blows to the steel, from the ‘large’ ball pein hammer, will not damage this type of vice, but they could damage an engineers vice.
