Any length, up to 4 stages, and all the power you need from Kraken X60 motors. Lock your telescope in place with either the ratchet and pawl or the WCP friction brake. Use it for fast and secure climbs, or any other fine-controlled linear mechanisms. Elevate your gameplay with the GreyT Telescope today! Some cool features:
Works with .060" and .125" wall tubing

The holes in the bottom of the Base Tube and top of the Intermediate/Base Tubes are used to pin the Top Blocks and Gearbox to their respective tubes. The holes in the bottom of the Intermediate Tube are used to install the Bottom Blocks, Hardstops, and CF Springs to their respective tubes. The top of the output tube will be determined by the user. This is the recommended spot for the Telescope String to anchor to, as it is the easiest place to do so.
Unless otherwise specified all holes are 0.196”, or clearance for #10-32 Bolts
All of the Step files below are compatible with the WCP Press Fit Drill Bushings (WCP-0321).
The jigs below ensure perfectly aligned and positioned holes for the 1 to 4 stage tubes. Simply cut your desired tube to length, slide it into the jig, and drill out the necessary holes.
We recommend installing a bolt after drilling the first hole to secure the tube and prevent misalignment.
The image below shows the equations for calculating the length of each tube. Each of the moving stages are 1/4” longer than the preceding stage, and the first stage is 1” longer than the base tube.
The max tube length for each stage (excluding the output stage) is roughly 40”. The is due to the max safe extension of the CF Springs sold by WCP, which is 40”.
