Push the washer up on the bolt as far as you can with your
fingers
(Figure 8a). Then place the insertion tube on the
bolt (Figure 8b) and use it to push the washer farther up
on the bolt, into the counterbored hole in the wood (Fig-
ure 8c). The washer will keep the bolt captive when it is
fully disengaged from the mating part of the base.
Repeat this procedure for the other five connecting bolts
to be installed in the front panel, and for the six addition-
al connecting bolts that attach the side panels and side
braces to the top baseplate.
4. Now attach the front brace (B) to the two side panels (C)
with the four appropriate captive connecting bolts. Use
the hand knob to screw each bolt into the threaded metal
receptacle recessed in the side panel. The side panels
should be oriented so the side braces are facing outward.
The front panel should be oriented so that the metal insert
(Figure 5, top) faces inward. Do not completely tighten
the connecting bolts yet.
5. Place the assembled side panel/front panel structure on
the top baseplate (D), aligning as best you can the pro-
truding connecting bolts with the holes in the baseplate.
The baseplate should be oriented so that the Ebony Star
azimuth bearing ring is facing downward. Turn the con-
necting bolt hand knobs to fasten the side panel/front
panel structure to the baseplate.
6. Firmly tighten all 12 connecting bolts installed in steps
4 and 5. Again, do not overtighten to avoid stripping the
threads.
7. The azimuth encoder board (E) attaches to the underside
of the top baseplate (D). Insert an encoder wood screw
through the slotted hole in the azimuth encoder board so
that the head of the screw is on the side of the encoder
board without the modular connector. Now, place the two
thick (P) and one thin (O) azimuth encoder spacer wash-
ers on the screw
(Figure 9). These washers are critical in
providing the proper spacing for the assembled azimuth
encoder. The two thick azimuth encoder spacer washers
are included with the base, but the thin azimuth encoder
spacer washer is included with the IntelliScope Object
Locator kit.
8. Insert the modular jack on the azimuth encoder board (E)
into the rectangular cutout in the top baseplate (D) and
align the encoder board so the screw lines up with the
pre-drilled pilot hole in the baseplate, and the large hole
in the encoder board lines up with the central hole in the
baseplate (
Figure 9). Thread the encoder wood screw
(with spacer washers attached) into the pilot hole with a
Phillips screwdriver and tighten until just tight.
Note: After the azimuth encoder board is installed to the bot-
tom of the top baseplate, do not rest the baseplate on the
ground, or the encoder board could be damaged. At this
stage, rest the partially assembled base on its side.
9. Position the ground baseplate (A) so that it is standing
on its feet. Place one fender washer (H) onto the azimuth
axis bolt (I), then insert the bolt up through the hole in the
ground baseplate. Now temporarily place a piece of duct
tape, masking tape, or packing tape over the head of the
azimuth axis bolt
(Figure 10). This will keep the bolt from
sliding downward as you install the top baseplate, which
you will do in step 11.
10. Place the azimuth encoder disk (J), flat side down, over
the azimuth axis bolt (I) and onto the ground baseplate
(A). Then place the brass azimuth bushing (F) onto the
azimuth axis bolt (I) so the wide end of the bushing is
closest to the encoder disk (J). Seat the bushing onto the
Figure 8. (a) Place a rubber washer on the threaded end of the
connecting bolt and push it on as far as you can with your fingers.
(b) Then use the included insertion tube to push the washer past the
threads on the bolt and up into the counterbored hole in the wood.
Figure 9. To install the azimuth encoder board, insert an encoder
board mounting screw through the slotted hole in the board. Then,
add two thick and one thin encoder spacing washers onto the screw.
Now, insert the modular connector on the encoder board into the
square hole in the top baseplate, and thread the screw into the pilot
hole using a Phillips head screwdriver.
