The (inside) cross elevation arm (part 111) is attached to the elevation drive (part 118) with a hidden sewing pin which means working from the inside out. Once again, the sewing pin goes through a couple of washers (parts 121) and is cut off slightly above the washers. A drop of super glue will (hopefully) bind the washers to the end of the sewing pin and form a rivet head.
Assembling the elevation drive is like building a wheel except the axle has to be reinforced with part 120 so it does not collapse when the elevation drive placed on the gimbal stand.
After part 118 is rolled into a cylinder and the 2 faces (parts 121) attached, the inside of the cross elevation arm (part 111) can be folded and glued inside the elevation arm assembly (part 110).
The gimbal stand is made of 5 parts so that the 4 corners are double thickness so it can (hopefully) support the weight of the UV telescopes.
Finally, another sewing pin is used for the elevation drive axle. Again, the sewing pin goes through a couple of washers (parts 128) and is cut off slightly above the washers. A drop of super glue will bind the washers to the end of the sewing pin so the sewing cannot work its way out of the axle.
