11/18/2000 - The
2 sides are glued on. Elmer's Carpentry Glue. I also screwed the
bottom on and sanded down the rear bulkhead and mirror cell so they
fit in. Also nailed sides to top with brads--it's starting to look
good!
Got some polyurethane to seal it with, also hardware for base assembly:
3/8" hex nut (2" long), wing nut, 2 washers and tee nut.
Got to figure out how the hell tee nuts work!

11/20/2000 - Primary and focuser arrived! So I was finally
able to draw an accurate diameter of the mirror on the cell. This
for determining 2.5" ventilation holes and dowel (holder) placement.
Today I cut those vent holes, and drilled a 1/4" hole through
center of cell and rear bulkhead for pull-bolt. Hammered in tee nut
to mirror side of cell. Drilled 3 holes in rear bulkhead and put tee
nuts on inside for push bolts.
Mirror cell with ventilation holes, tee nut in center, and dowel holders.
Cell is attached to rear bulkhead via middle pull bolt. |

11/23/2000 - Cut
out the side bearing circles yesterday. The next thing I have to
do is sand the base cicles so they are perfectly circular. Then
I can glue the formica to base and route it out. The semi-circle
cutouts on the mount should be pretty accurate, but since the bearings
(side) will rest on the Teflon strips it is not that crucial. Also
need to prime and paint inside of tube and base.
