Once I have the design finalized, my plan is to print the gear out of the same Nylon 11 as the worm. I envision this mount as having a load capacity of 4 Kg. AU $37. 8 deg step and 8-32 micro steps. I can attest that the optics on this particular scope are also excellent, a certificate from Celestron attesting to that fact aside. The worm gear itself is simply a screw, captured in place and running in bearings, that accepts the input motion. Jump to content Sign In Create Account ; View My last sentence specifically mentioned the extra care needed to produce a precision telescope gear. Is there some kind of calculator I could enter in the diameter/thickness to see what kind of tooth range I would get? 10000+ "telescope worm gear" printable 3D Models. To make the worm gear I filled the wheels with JB weld epoxy using a 2mx1/2"-20 nylon screw that can be blended for Suggesting only the illusion of lateral PA movement when the 6" telescope was used as a lever in the video. the base scope is a celestron super c8 plus with pristine optics. Part 10: Cutting the worm Once the telescope is put into position, we engage the worm and worm gear as shown in the picture below (spring behind the worm gear is not visible). Category: DIY Page 1 of 2 - Timing Belts for Telescope Drives - posted in ATM, Optics and DIY Forum: All this talk about custom gears etc. Attach to a Part 6: Gashing the worm wheel blank gear teeth. Home; Contacts; About Us; Blog Backlash trouble in your telescope mount?In this video I will show you how to optimize the AZ/EQ-G's worm drives for smooth, backlash-free motion. 5 mod in this case). PLA is really cheap and prints MUCH faster than the Nylon 11 so its perfect for prototyping. Page 1 of 2 - video on making worm and worm wheel - posted in ATM, Optics and DIY Forum: I am not sure if this was already posted by any other members. 89999:1 You will also need a worm gear to control the field rotation and mounts to secure the motor. Then open Cartes du Ciel and click on the Telescope tab. No worm gear is perfectly round. - posted in ATM, Optics and DIY Forum: FYI the way Boller & Chivens did their worm block is that it’s on a pivoting arm. Part 12, Hobbing the worm wheel. There is no clutch, you balance the telescope ( which weighs a ton or so) by partially disengaging the worm. In these pages, I describe how to make a Do It Yourself (DIY) Telescope Controller. Now for the good bit, using the hob to cut the teeth in the gashed worm wheel blank - finally it will become a real worm wheel and not a worm wheel blank! Page 1 of 2 - Yet Another DIY RA Drive for Eq5 / Exos2 / Eq3 etc etc - posted in ATM, Optics and DIY Forum: Ive been a lurker in CN for long enough its time to give something back, I hope! Here is yet another DIY project to add a RA motor to your mount, overall cheap but with some high-quality details. FROM DIY GEARS BOSTON MASSACHUSETTS REDUCER BRONZE. 5/0. Attach a stepper motor on a telescope’s Housing: Die-forged Aluminium Alloy Gearbox (NMRV571~NMRV090)Solid Iron Gearbox (NMRV110~NMRV150)2. Indeed. You do need a lathe however, and a lot of builders who know how to use one can use the method described here. This can be an optical sensor or a Hall-Effect sensor. I have a lot of ideas of things Id like to try that are different than most commercial mounts. CGEM/CGEM DX/CGX/CGX-L Ceramic Worm Gear Bearings Upgrade Kit DSP-HYPDIY-CGEM-CWGB $55. 6 out of 5 stars 3. Components Hypertuned CGEM Page 1 of 7 - NEW Losmandy G11 spring-loaded worm gears - testing and review - posted in Mounts: Hi everyone, I have been testing new Losmandy spring-loaded axis and wanted to share my experience and results. They overcome backlash because each axis has a DC brushed torque motor running on constant Today I forced myself to tackle these issues, and now the DEC worm is pressing against the worm gear on the DEC axis of the telescope mount. One of the most impressive things you can make on a mini-lathe is a matched worm wheel and worm gear set for a telescope mount. The DEC is a 7 with clutch plate. If I make any progress maybe I'll put my blog back online. [] sales@china-gearboxes. Page 1 of 3 - Designing a goto Mount - posted in ATM, Optics and DIY Forum: Hi first time posting on the forum. Probably the same reason the LX200ACF does. Cant afford a high-end mount, and hunted down the Byers worm gears. This ties a motor to a specific mount (or a differently branded clone). All plates and bearing housing is alu the shafts are Alternatives to GEMs for DIY mounts - posted in ATM, Optics and DIY Forum: Hi everyone - Im a relative newbie to astronomy, only in it about a year, with a strong background in DIY. I have a nice 10" GOTO scope, but it is not really portable NOTICE: The new version now released! EQ mount II for small telescope or DSLR, desing for OnStep goto controller. Id like to build the next one for an ETX-125 as an open fork with worm drive on both axes; the main structure will be plywood. The The original Meade DS and ETX models use a very small 60 tooth 48 pitch worm gear with an OD of 1. com. Every Day new 3D Models from all over the World. An inexpensive Arduino Uno board and L293D-based stepper motor driver can be used to control a telescope. Only 3 left. English en. On the other hand, Type B offers a compromise between size and portability, ideal for I’ve made all manner of astrophotography gear in the past with varying degrees of success. How To Mount Worm Gear? - posted in ATM, Optics and DIY Forum: What is a suitable method to support the worm meshing with a worm wheel? The worms and wheels are from Beacon Hill Telescopes [UK] The wheels are 11" RA and 8. Due to a VERY slight eccentricity of the shaft, if I set 5 – Adjusting Worm Gear Engagement – Motor Gears; 6 – Adjusting the Altitude Thrust Bearings; 7 – Appendix – Hardware and Software History; Rebuilding the SkyWatcher EQ6/Orion Atlas Mount. number of steps for a complete worm rotation (in RA), My DIY Telescope; NOTE: Use stones and cement to fill the weights. Declination Worm Gear replacement for Celestron Advanced VX Series Telescopes. In 2019, in an attempt to improve the autoguiding performance of my german equatorial mount, I went through the process of retrofitting my Celestron CGEM to OnStep Telescope Mount Goto Controller. They are only the 5V steppers but if I do it that way, driving a separate worm gear from the attached gearbox I'll have to recalculate speeds and ratios. I have high hopes for this. One of them is the idea of using spur gears instead of worm gears for the Page 1 of 2 - Timing Belts for Telescope Drives - posted in ATM, Optics and DIY Forum: All this talk about custom gears etc. I know that at least one commercial Source for gears - posted in ATM, Optics and DIY Forum: Im looking for roughly a 3-4 gear with a worm gear. I already have a couple of spare worm gears from my G11 so I don't need to be making my own worm gear. Decided I needed a worm gear somewhere around 3" in dia Tag Archives: telescope worm gear 20W diy telescope worm gear price China in Cuautla Morelos Mexico DC 24V Worm Gear Motor for Height Adjustable Equipment with top quality. : >>>New electronics and remote used photos added. 5arcseconds or less relatively easy in Telescope clock drive controller based on L293D and Arduino Uno board. Various things have been purchased such as bearings. Wormgear drives are good for big gea Wormgears are made in this video using the hobbing process. My stepper motors can work with 1. I have an old Meade 16, the drive motor still works, the Not servos. You can in principle make worm and worm gear with standard bolt and tap for same thread and hand drill - look at this video for example: ALUMINUM / STAINLESS STEEL TELESCOPE WORM GEAR SET 360 TEETH 360:1 RATIO NEW ! !
