Hot Water Fiber Bending Procedure (view source)

The light guide is offset soon after the SciFi section in an S-bend to reduce the amount of fiber exposed to the electrons' trajectory. Fibers are placed within a water tank, heated with the water, then bent and cool within the tank. The process takes many hours.

**'''Note:''' While working with one end of the bundle, always be cautious of the other end. Any bends may cause damage to the fiber.

*Secure both plates to the bar with clamps.
*Secure both plates to the bar with clamps.
*Repeat the process for placing fibers in the chimney slots. Again starting with the right-most column, and the bottom fiber going into the right-most slot. Repeat the chimney and tag-removing process.

===Placement into Popsicle Stick===
This step requires two technicians.
*Remove the collar tops of the first and second collars nearest the popsicle stick.
*Secure a chimney clamp onto the bending plate and rest the SciFi ends of the fibers against it so you may attach the popsicle stick to the bending plate without having to hold the fibers.
*Have one technician tilt the entire bending unit (bending bar, bending plate, and chimney plates) with both hands so that a second technician can attach the popsicle stick to the bending plate. Place a large washer between the popsicle stick and the bending plate. This is so the fibers do not have to bend.
*While holding the fibers in the proper oriented matrix, place the fibers gently into the popsicle stick. They will jut out of the end because of the extra length.
*Gently place the popsicle stick top onto the fibers without stressing them, and put the two rods through the popsicle stick. The rods are different, so if they are not properly aligning with the threaded rods, switch their positions.
===Filling and Siphoning the Tank===

**Keeping the siphon underwater put the hose into the inlet of the left exclusion area and pump the siphon until no air comes out of the outlet of the left exclusion area.

===Running the LabView Program===
*Plug in both netbooters. They are located on either side of the tank.
*Open the "2 Heaters 1.2" Labview program.
*Click on the dials for "Heater and Pump 1" and "Heater and Pump 2" to turn on all water heaters and pump.
**There are three temperatures listed on the interface. There is the water temperature, and the two surface temperatures of each heater. Watch for a bit to make sure neither heater gets more than 3-5 degrees Fahrenheit hotter than the water temperature.
