  1. Cutting the Shield and Strap on the Colex Sharpcut.
    • Two computer PDF templates located below are needed for the Sharpcut. These two templates are used to maximize material usage and are designed for 48” x 96” material. (Templates can be modified for different sizes)
    • To balance the number of parts template 1 needs to run 8 times and template 3 needs to run 1 Time. This will produce 219 sets of parts.
    • Both programs use the same Tool Setup with the Oscillating Knife in Tool 2 and the Double Edge Knife in Tool 3.
      1. Tool 2 Feed Rate = 100 in./min. Plunge Rate = 300 in./min. (Runtime= 16 min.)
      2. Tool 3 Feed Rate = 350 in./min. Plunge Rate = 300 in./min. (Runtime= 61 min.)
      3. One item to note: The bottom left corner of the material has a tendency to lift while cutting in this area. Taping down this corner to the bed to the material alleviated this problem. Reorganizing the layout to limit the amount of cutting in the corners and edges is a better long term solution.

Prepping Components for Assembly

The PETG has a protective film on both sides. This film needs to be completely removed from the Strap and the on Shield it needs to be pulled back from the corners on both sides to allow the installation of the rivets. See illustrations below.

Assembly

1. All parts ready for assembly

2. Attach adhesive backed neoprene rubber to strap. There are small marks in the strap used for alignment.

3. To rivet the Strap to the Shield, insert the rivet into one of the holes in the strap. Be sure to insert into the same side that the neoprene pad is on. This will keep the smooth end of the rivet against the wearer’s head. This method of using the rivets allows the Shield to pivot if user wishes.

4. Next place a washer onto the rivet and then the Shield and finally another washer. Then set the rivet using the rivet tool.

5. Repeat with the other side of the shield.
