16. Use the pins to align the copper template to the acrylic. The pins are a little too large to go into the holes in the acrylic, and must be tapped in with a small hammer. There may be a burr on the end of the pins and should be filed down so that no sharp edges damage the acrylic, or cause it to crack. Place the copper over the pins and tape in position. Pierce a saw blade clearance hole somewhere in the area to be cut out and proceed to cutout the shape made by the die. Saw inside the line and file up to the edge. The opening in the acrylic must match the opening in the copper exactly. Do not file into the copper.

17. Use the pins to align the copper template to the CRS. While aligned, tape the two pieces together and remove the pins. Pierce a saw blade clearance hole in the CRS and carefully saw out the opening. This must match the copper template exactly, as this will be the edge that the blanking die will cut to.

18. Secure the steel face plate to the acrylic with double-stick tape or super glue. The alignment pins will protrude through the front face of the steel. Place the blanking die on the pins, and using a file, file the pins down until they are flush with the outer surface of the blanking die.

19. Now, use the matrix die in the normal fashion to form your part. Be sure to trim the metal enough so that it remains within the pins. These pins will point down into the polyurethane pad, but are so short that they will not bother anything, or do any damage to the urethane.

20. After the part is fully formed, place it in the blanking die. Look at the die from the "puffed" side and visually align the part until the die exactly matches the outline of the part. Place the blanking die back onto the matrix die, using the alignment pins for registration. As you can now see, the matrix die protects the form that it created. Place back into the press and blank out your part.

As you can see, this is not a process for making only one or two parts. You have to be thinking about multiples to make this system make sense. Having made the first one, it becomes infinitely easier. Thanks for working through this project with me and I hope that you have enjoyed it.
