ASSEMBLE THE BASE

STEP  1:

The  base  supports  the  telescope  and  allows  you  to

move the telescope from side to side.
Line up one of the base side panels (9) with the base front panel

(10) as shown here. Thread in the two black attachment bolts to

secure the panels together. Tighten the bolts to a firm feel.

Repeat with second side panel.

STEP 2:

Turn the base panels on their side.

Line up the circular base(11) with the 7 predrilled holes against

the panels. 

Thread 6 black bolts into the base, as shown here. Make sure that

the side with the countersunk holes on the base face the bottom

(see photo)

STEP 3:

Slide the  center bearing bushing into the 7th (center) hole of the

circular base.
Line  up  the  other  circular  base  (sometimes  called  the  ground

base).

Note:  only the 16” LightBridge is equiped with three teflon pads

(finger points to a pad).

STEP 5:

Next attach the three feet to the bottom panel. Line up

each  foot  and  thread  a  small  attachment  screw  into  the  foot  to

hold it in place. Tighten to a firm feel.

Note:

When  attaching  the  feet,  make  sure  that  the  center 

countersink  depression  is  on  the  opposite  side  of  the  base.

STEP 5:

Next attach the three feet to the bottom panel. Line up

each  foot  and  thread  a  small  attachment  screw  into  the  foot  to

hold it in place.  Tighten to a firm feel.

STEP 4:

Place the center bearing bushing into the countersunk hole of the

ground plate. Slide the three roller bearing plates over the center

bearing  bushing:  First  the  roller  bearing  plate,  then  the  roller 

bearing itself (the plate that looks alike a wagon wheel), then the

second roller bearing plate. Place the top part of the base plate

assembly over the center bearing bushing. 

To secure in place:

On the adjustment knob bolt, place two washers on either side of

the roller bearing washer . Slide the adjustment bolt through the

top  base  board  and  into  the  center  bearing  bushing  and 

hand-tighten. A nut is captured on the bottom plate. See drawing

Note:

You will need to supply a phillips screwdriver and a one-

quarter inch or adjustable wrench to assemble the telescope.

Note:

Numbers in parentheses. e.g., (9), refer to Fig.1 and Fig. 1

insets.

Looking at or near the 

Sun

will cause 

irreversable

damage to your eye. Do not point

this telescope at or near the Sun. Do not look through the telescope as it is moving.
