Fretz Hammers And Their Uses

Fretz Hammers And Their Uses

Planishing is smoothing the metal against a stake by making the hammer blows overlap. This is a stretching technique which forms the metal to the underlying stake. Planishing can be on flat, convex or concave shapes.

Raising is the compression of metal down to the stake without stretching it. The technique involves angling the metal off the stake so there is an air gap for the compression of the metal.

Embossing is the stretching of the metal by hammering from the inside of the form. This group of hammers is also used to form flutes and form the metal while it is supported by pitch or wax. This is similar to chasing but is done by directly striking the metal with the appropriate hammer.

Blocking is a form of embossing when the metal is hammered into a hollow cavity. Free form Blocking is done with a sandbag.

Chasing is a way of forming the metal with a hammer and small chisels or punches. The metal is compressed downwards as the chisel strikes the metal over pitch, wax or an underlayment that supports the overall form.

Riveting is the compression of a rod or tube so the ends flare and hold two or more units together as the rod or tube passes through the parts. The Riveting Hammer's crosspien end flares the rod so it develops a head and the broad face smooths out the flaring marks.
