Drove Chisel

The bush hammer is a flat chisel to the surface processing ( flattening and structuring) of soft rock, such as sandstone and limestone, after the bosses has been performed largely by means of chisels and dental iron or Krönel. It is regionally also called broad iron.

Tool shapes

Depending on the hardness of the material to be machined are cutting width and thinness of Scharriereisens different. Quarter irons have a cutting width of about 40 to 60 mm, half- iron 80 to 100 mm wide and iron up to 240 mm. The blade runs in bush hammer for very soft rocks towards the shaft of heart-shaped. For the heavier editable marbles and limestones the bell or cup shape is employed. Bush hammer are powered by wood or Gummiknüpfeln.

Tool marks

The bush hammer leaves parallel recessed grooves (called strokes ) on the stone surface. The tool marks are called Scharrierhieb, throat slashing or whichever as Breitscharrierung or Schmalscharrierung. A Scharrierhieb with special optics call the masons such as " Hamburger Bauhieb ", a chop, which is performed with a double whammy.

History

Tool marks of Scharriereisens can be detected from about 1450. In older German literature, it was thought the tool was from France. The younger, especially French research does not confirm this.

In the Gothic period was about 60 ° inclined and chiseled from the Baroque period perpendicular to the edge. A Scharrierung of modern times is the so-called colorful bushhammering. This results in checkerboard-like pattern. In addition, can be generated by the different attitude of bush hammer herringbone pattern on the stone surface. Dielectric techniques of stonemasons created different sized grooves up to 3 cm half radii. Usually there are grooves 2-3 mm. In particular, in the Baroque, there were special bats on stones.
