We did this project as 2 separate parts. The models were made directly from old rail road drawings. These parts were produced in rapid prototype direct to stainless steel at Shapeways.com. The parts are only a few inches long. Models and final product displayed with permission from Kevin Sprayberry.
 This is the drawing.
  Here are the SolidWorks Models. Note the inner web/fillet was unnecessarily removed for manufacturing considerations.   Here are the finished parts. 1/2 inch "T" slot in backround for scale. |
