An adjustable cutting stroke length is provided by a wobble plate mechanism. A wobble plate mechanism imparts reciprocating linear action to a working end of a reciprocating motorized tool. A drive source is included that has an axially rotatable main drive shaft that is selectively rotatable in one of two opposite directions. The main drive shaft is configured to engage a wobble mechanism that provides the reciprocating linear action to the tool's working end. One of a first stroke and a second stroke is provided to the working end of the tool by the wobble mechanism. When rotation of the main drive shaft occurs in a first direction, the working end is provided with a first stroke. Furthermore, when rotation of the main drive shaft occurs in a second direction, the working end is provided with a second stroke. Elements used for adjusting the stroke length are placed on one axis only. |
