Thermoforming Flow Reducers

	Cut a 6” piece of larger diameter tube (at least 1-1/2”). Cut a slit down the length of the tube.
	Place the tube with the slit in the oil. You'll want to hold the piece with a pair of pliers so that the entire piece can be placed in the oil. Once the tube has opened up into a flat sheet, quickly remove the PVC and place between two flat boards. Press the two boards firmly together for 15 seconds. With a pair of pliers, remove the flat plastic piece and quench in water for 15 seconds. Dry and clean with cloth.
	Using a drill with hole saw attachment, drill through the plastic into a board underneath. Note: It is hard to find hole saws with a guide besides the 1/4” drill bit. When looking at pressure in your system, make sure to run NeatWork software with only 1/4” flow reducers. If you cannot have a system only using 1/4” flow reducers, you will need to drill a larger hole once you have made the flow reducer. You will need to use a larger drill bit and some type of clamping mechanism from keeping the flow reducer from moving while drilling.
	Here is the finished flow reducer. Clean with a file before installing.
