baseplate. Make sure the short nylon bushing seats up into the hole.
7.Now temporarily place a piece of duct tape, masking tape, or packing tape over the head of the azimuth axis bolt (Figure 8). This will keep the bolt from sliding down as you install the top baseplate, which you will do in step 10.
8.Place the azimuth encoder disk, flat side down, over the azimuth axis bolt and rest it on the bottom baseplate. Make sure you’ve got the correct encoder disk! The azimuth encoder disk has a smaller center hole than the altitude encoder disk.
9.Place the brass bushing onto the azimuth axis bolt so that the wide end of the bushing is closest to the encoder disk. Seat the bushing onto the encoder disk so that the registration feature on the bushing goes into the hole in the encoder disk. You may need to move the encoder disk around on the azimuth axis bolt a bit for the bushing to seat properly.
Note that for the IntelliScope version (#27126) of this tele- scope, you will not need the long nylon azimuth bushing and Teflon bearing disk that you removed during the baseplate disassembly (Figure 4). Those parts are only utilized for the

the center hole of the top baseplate. Place the remaining fender washer onto the shaft of the azimuth axis bolt, then thread the hex lock nut onto the end of the bolt and tighten it only finger tight, for now. Note that the brass bushing protrudes slightly above the surface of the top baseplate. This is by design.
11.Tilt the assembled base at a slight angle (as little as possible) and remove the tape from underneath the bottom baseplate. Now, with one wrench (or pliers) hold the head of the azimuth axis screw still while turning the hex lock nut with the other wrench (Figure 9). Tighten the hex lock nut just until the top fender washer is no longer loose, then tighten the hex nut 3/16 to 1/4 turn beyond that. This ensures proper spacing between the encoder disk and the azimuth encoder board.
12.Attach the encoder connector board to the side panel. Place a wood screw into each of the four holes of the connector board and then a washer onto each screw. Sliding the washers all the way down on the screw shaft should help keep the screws from falling out while installing the board. Still, the installation may take a bit of dexterity, so don’t get frustrated if it takes a couple tries. Align the screw tips with the four
