Spokeshave

The tail planes, spokeshave or knacker is a Slicer for working wood. It is particularly used to edit heavily curved shapes. The plane sole and the iron in the transverse direction can be straight, convex or concave, the sole work in the direction of flat or convex. For processing large areas it is not very suitable.

Early, made ​​before the 20th century models were manufactured with the exception of the plane iron and possibly the sole of wood. They have a lower angle of attack of the planing blade than their younger counterparts with iron body.

Handling

With the spokeshave can " to train " (that is, pulling it towards you ) or to work under pressure. He is out with both hands.

Simple models clamp the iron fixed with a single screw. Thus, it has the correct distance from the sole - it may only be made ​​into very thin shavings -, press the spokeshave on a medium hard, flat surface such as a piece of wood, uses the iron and pressed it down. Then the iron is bolted using the metal flap.

Newer models are equipped with trim screws. They facilitate the accurate setting of the iron and prevents also that the iron while working shifts upward and the removal is lower. Models without trim screws must be adjusted for this reason often.

For work on concave ( curved inward ) pieces of wood spokeshave be used with a special rounded sole.

Improper handling can result in so-called " Ratterspuren ". This can have several causes:

• The iron is too far forward, so that too much wood is removed
• The iron is not hot enough
• The edited piece of wood swings, such as when it is too thin and is not lined.
• The pressure on the Spokeshave is too low

The tracks are formed when the iron eats too deep into the wood and the spokeshave is slightly tilted by the resulting resistance, so hooked and then jumps.

Use

By the end of the 20th century, the spokeshave was in woodworking crafts and probably also used in leather processing. Meanwhile, he was largely replaced by machines, but found in traditional manufacturing methods, in particular for single pieces, continued his application.
