Page 23 GreyT Telescope - User Guide (Rev 1) Gearbox - Step 8 Slide the assembled Drum from Step 1 onto the output shaft. You may have to loosen the #10-32 x 3/8”L bolt in order to do this. Once the Drum is in place, check that the flange does not rub against the Gearbox Plate when the output shaft is spun by hand.
Page 24 GreyT Telescope - User Guide (Rev 1) Gearbox - Step 9 Bolt the two halves of the gearbox together. The bolt locations for the different Gearbox configurations are shown on the following four pages. When the Gearbox is fully assembled, make sure the Drum Flanges do not rub against the Gearbox Plates when the Output Shaft is spun by hand.
Page 25 GreyT Telescope - User Guide (Rev 1) Gearbox - Step 9 (1-1/2” Base Gearbox) The images shown below mark out the bolt locations in green, blue, and orange. These configurations of the Gearbox both use #10-32 x 2”L bolts and 1-1/2”L spacers.
Page 26 GreyT Telescope - User Guide (Rev 1) Gearbox - Step 9 (2” Base Gearbox) The images shown below mark out the bolt locations in green, blue, and orange. These configurations of the Gearbox both use #10-32 x 2-1/2”L bolts and 2”L spacers.
Page 27 GreyT Telescope - User Guide (Rev 1) Gearbox - Step 9 (2-1/2” Base Gearbox) The images shown below mark out the bolt locations in green, blue, and orange. These configurations of the Gearbox both use #10-32 x 3”L bolts and 2-1/2”L spacers.
Page 28 GreyT Telescope - User Guide (Rev 1) Gearbox - Step 9 (3” Base Gearbox) The images shown below mark out the bolt locations in green, blue, and orange. These configurations of the Gearbox both use #10-32 x 3-1/2”L bolts and 3”L spacers.

Page 31 GreyT Telescope - User Guide (Rev 1) Gearbox - Step 11 Install the 3D Printed Mag Encoder Mount using two #10-32 x 1/2”L bolts. To install the Mag Encoder, remove the board from the case and fit it into the cutout on the 3D Printed Mag Encoder Mount.
Page 32 GreyT Telescope - User Guide (Rev 1) Telescope Assembly Instructions These instructions show the assembly for one stage. For any extra stages, repeat steps 2-5 before running the string. Note: Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole�...
Page 33 GreyT Telescope - User Guide (Rev 1) Telescope - Step 1 Slide the Base Tube for your Telescope into the gearbox. In order to do this, loosen all bolts and remove all #10-32 x 3/8”L bolts. The 4 holes in the Base Tube will align with the holes for the #10-32 x 3/8”L bolts.
Page 34 GreyT Telescope - User Guide (Rev 1) Telescope - Step 2 Slide the correct Top Block and Bottom Block onto the Tube for the next stage being assembled. For example, the images below show the 1-1/2” Tube with the 2” Top Block and the 1-1/2”...
Page 35 GreyT Telescope - User Guide (Rev 1) Telescope - Step 3 Bolt the flat tab of the CF Spring through the Tube into the Bottom Block using an Ultra Low Profile #10-32 x 3/8”L Bolt. Repeat this step for both CF Springs in the Top Block.
Page 36 (Rev 1) Telescope - Step 4 Pull the Top Block down the tube. Bolt the correct GreyT Telescope Hardstops to the tube using Ultra Low Profile #10-32 x 3/8”L Bolts. These bolts should thread through the Hardstop and into the Bottom Block. The hardstop used must be cut to the same width as the tube it is being bolted to.
Page 37 GreyT Telescope - User Guide (Rev 1) Telescope - Step 5 Slide the assembly from Step 4 into the correct tube. For example, the image below shows the 1-1/2” Tube being slid into the 2” Base Tube. Loosen the 4 bolts on the Top Block and slide the Top Block over the end of the larger tube.
Page 38 Note: If any of the bolts used in this step rub against the smaller tube while it is moving, add 0�010” thick #10 Washers (WCP-0038) underneath them until they no longer rub� Table of Contents Page 38 wcproducts.com...
Page 39 (Rev 1) Telescope - Step 6 (Continued) If you are assembling the 1 to 1-1/2” Stage without the GreyT Telescope Hardstop, make sure to only thread in the left hardstop bolt in the top block. If both bolts (or just the right bolt) are used, the hardstop bolt may dent the slot for the Bearing Stack-Up in the 1”...
Page 40 GreyT Telescope - User Guide (Rev 1) Telescope - Step 7 (Non-Flipped) The string will be attached to the Drum using the #10-32 x 3/8”L bolt installed in Gearbox - Step 1. From there, drop the other end of the string through the bottom of the assembled Telescope and fish it through all the stages.
Page 41 GreyT Telescope - User Guide (Rev 1) Telescope - Step 7 (Flipped) The string will be attached to the drum using the #10-32 x 3/8”L Bolt installed in Gearbox - Step 1. The other end of the string will attach to a custom plate or shaft created by the user.
