assembly of the Dobsonian Base The base of the XX14i was engineered by Orion to allow quick disassembly into several component pieces, to make it more manageable to transport in a standard size vehicle. Assembly is also fast and easy, thanks to a dozen connecting bolts with attached hand knobs. The bolts thread into custom threaded receptacles that are embedded in the adjoining baseplate or side panel. To ensure that you can never lose them, the bolts are held captive in the base when ful

Figure 24. Rather than assembling the entire optical tube and then hoisting it onto the base, some may find it more convenient to mount the lower tube section on the base first, then install the truss tubes and upper tube section. Note: If desired, you can mount the lower tube section on the base before connecting the truss pole assemblies and upper tube section (Figure 24). You may find it easier to lift the lower tube section and guide it onto its resting place on the base’s bearing cy
