Preparing the Teflon liner

A Teflon sheet is used as a liner for the inside of the electrolyzer. It prevents contact between the metal mesh positive electrode and the metal inner walls of the electrolyzer. The Teflon that we used has one adhesive-compatible side which is brown. This adhesive-compatible side faces inward when constructing the electrolyzer so that spacer strips of silicone rubber can be glued to its surface. The white side of the liner is the outside of the liner and faces the inner wall of the pipe nipple. 

Mark the port holes for the positive electrode assembly on liner 

Apply epoxy to the sanded surface of each silicone rubber strip and lay each one on the liner, centered along the lines drawn. Let this dry for 24 hours. 

Attach the top and bottom screw-on flanges to the pipe nipple. 

test by screwing on the flanges to the pipe nipple to see generally how much travel you get. The screw-on flanges will not cover all the threads on the nipple. This test will indicate how much of the nipple to thread seal and tape.
