Last Time You Will See the Base

It will still be there, of course, but you will have to exercise your observing skills to remember to notice that this essential part of the telescope is there, under the steel, glass and electronics all piled on top of it.  Thanks to Mark for this series of construction and assembly photographs that document the transformation of two sheets of Baltic Birch plywood into the sturdy base that will hold the telescope – think of it as the daisy wheel for the universe.

Guide to the slide show:

  1. Planning to cut something so expensive that they measure three times.
  2. Larry is drilling a hole under Mark’s supervision
  3. It’s two pieces glued together
  4. At their feet – the three piers temp mounted on a much cheaper piece of plywood, with a plywood diaphragm that centers the azimuth axis, installed right in the middle. The base plate is propped up to their left.
  5. This close up of the piers and diaphragm also shows the black-painted bogey wheels, a pair on each pier, that will be what supports the daisy wheel, er, base plate.
  6. The shiny ring is the aluminum azimuth drive bearing, attached for the first time to the base plate. The ring rides on top of the bogey wheels as it rotates the telescope.
  7. Pier assembly and base plate assembled – take a good look!
