New strategy (need 2 people)

Materials Required:

• Scotch tape (tape 
• Light source (very bright, and focused)
• Hole puncher/pen/sharp thing 
• Gridded paper strips 
• Thermocouples
• Thin rods (support the thermocouples)
• Mini C-Clamps (see clamp drawer in lab)
• Aluminum Tape 
• Willpower and patience 

1. Take a strip of tape that is lengthwise X inches (chosen exterior diameter of the NC), and using a pen mark out 3 equally spaced segments (do not cut)
2. Lay the tape strip at a chosen location on the NC.
3. Lay gridded paper strips along the exterior surface of the NC (3, 120 deg apart) by aligning the central lines on the strips with the pen marks on the tape. Use extra tape to secure the gridded strips.
4. Punch holes into points of interest on the gridded strips
5. Use a bright light source (flashlight, super bright LEDs, whatever) to shine a reference point through the NC
6. Have another person mark the point OR skip to 5.
7. Fix thermocouple bead to point of interest and apply Proline 4500 epoxy to cover the bead
