For the long tanks I used 44mm EMA hemispheres and tube. I made some u-shaped brackets from brass box sections which were bolted to the hemispheres at one end of the tanks. For the other end I got some aluminium pieces which were turned by a friend of mine. |

The middle of the long tanks needed to have a larger diameter, but the next size tube up from 44mm was too big so I increased the diameter by gluing thin layers of styrene around it. I cut the styrene a bit wider and longer than needed. Superglue gel was applied to half the area, and the styrene was clamped in place. When the glue had dried, I cut off the extra length and made sure I had a good joint. Then the rest was glued and clamped in place. After three layers were fixed, I sanded the ends flat. |

The spherical tanks were made from two 38mm hemispheres stuck together. They had a 3/16” hole drilled at one end and a smaller one at the other. These then attach to the 3/16” brass tube supports on the frame. |

The turned aluminium pieces were fixed to the hemispheres using epoxy glue. Long bolts were fixed through the aluminium using J-B Weld. The tanks were then glued together and permanently fixed to the framework by bolts at one end, and gluing the aluminium to the inside of the brass rings. A nut and spring washer then holds on the main engine bells. |
