TUBE ASSEMBLY: 1) 2) Remove all items from packing and inspect for damage and or missing parts. Clean and de-grease all parts to be joined using MEK. This would include all fittings,aluminum end caps, and ends of glass tubes. Also clean the glass cooling jacket inside and out around the holes for the water fittings. This can be done using Q-Tips dipped in MEK. Devise a way to hold the cooling jacket in a horizontal position elevated off the work surface at least 1” with the two holes facing downward. Mix up a small amount of epoxy being careful to mix equal parts resin andhardener, and glue the two flared water fittings into the holes in the cooling jacket, inserted from the inside. Use a supplied brush to apply the epoxy to the flared end of the fittings first, before insertion into the tube. Use enough epoxy to ensure a good watertight seal. Rotate the fittings in the glass to ensure even distribution of the epoxy. When satisfied with alignment of the fittings, (they arestraight, etc.) set the assembly aside to cure with the fittings facing straight down. SEE FIGURE # 1 Using the same mix of epoxy from step 4, glue the two machined gas fittings into their respective holes in the aluminum end caps. Again, apply the epoxy to the fitting only using the brush. Avoid using too much glue. Rotate the fittings into the end caps to ensure even distribution of the glue....
