Abstract: A fixture for mounting an article to be worked on including a base having an end member together with an arm pivotally mounted on the end member. The end member is formed with a multiplicity of spaced holes on radii extending from the pivot point of said arm, and the arm has a spring urged pin for engagement in any of said holes whereby the arm may be selectively positioned. Rotatable and slidably mounted on one end of the arm is a supporting arm which has a slot formed therein in which screw members are selectively positioned for threaded engagement with an article.
