Abstract: A method for creating fixtures used in the build of prototype parts, including a base plate having various holes and notches with various details mounted onto the base plate, and wherein the various details are used to support a prototype part, and the prototype part is created by using the fixture. The method comprises the steps of first using a milling or other process for producing a base plate having the predetermined precisely located holes and notches. An electrical discharge machining process is used to create the various details. The details are then assembled onto the base plate to create a predetermined fixture. The fixture is then used to create the prototype part.

Abstract: A walking aid adapted for use either before or behind the invalid user and comprising a pair of tubular side sections spaced apart and connected by a transverse brace at one pair of opposed ends to form a four legged free standing walker frame. Each side section support and adjustably disposable upwardly extending hand support enable the latter to be best positioned for the user and for the use of the walker in either its fore of after the patient position.
