This housing looks very simple and straightforward, but this is highly misleading and the materials are veryexpensive, so any error is costly. The construction accuracy needed is very high indeed with manyopportunities for a total and expensive disaster. Ed Holdgate has built several custom fixtures to ease theconstruction, but construction is still very difficult even with these specialist fittings and his years ofexperience. "Sikaflex 291" or "Marine Goop" marine bedding compound can be used to seal between thetwo slotted sides and the slotted base, and between the slotted sides and the two end inserts, in order toprevent any leakage between the acrylic and any of these inserts.The accuracy required for the slots to hold the stainless steel plates is 0.0003” and the plates are taperedwith a belt sander on both sides along all four edges so that when they are forced into the slots they will notcut into the sides of the slots. This produces excellent leakage characteristics, but don’t lose sight of the veryhigh accuracy of the slot cutting needed for this. The edges of the slotted inserts receive a bead of Sikaflexmarine bedding compound attaching them to the acrylic box and the compound is allowed to cure beforeconstruction is continued.The end plates with the stainless steel straps welded to them are used to connect the electrical supply to theplates, keeping any connection which could possible work loose and cause a spark, completely outside thehousing. Even though the straps are welded and there is no likelihood of them coming loose, the welds arestill kept below the surface of the electrolyte.Getting and Preparing the Plates:A set of 101 plates is needed for the electrolyser. The material used when making the plates is veryimportant. It should be 16-gauge 316L-grade stainless steel as it contains a blend of nickel and molybdenumin the correct proportions to make it a very good catalyst for the pulsing technique.
