The only downside is that a Dob doesn’t … - Selection from Astronomy Hacks [Book] . After some poking and googling I was able to determine that the mount uses a bipolar stepper motor to compensate for Earth’s rotation. Instead of a stepper motor, had you considered using a cheap clock kit, and just gearing it down 2:1 (or using the minute hand with a worm-drive attachment)? Also, you need to make use of exact alignment can be obtained by placing a shim under one Screw Driver I considered the barn door type design, but there are a few problems with this design. In this step you will need to create three separate panels that will house the ball bearings on which each shaft will rotate. Equatorial mounts can also be expensive, particularly if they are computerized for "Go To Once your gears are in their final position create a new work plane offset from the surface of one of the gears. This will be the surface upon which you will create the shape of the gear box housing. (See second illustration.) Extrude this to the width of the acrylic sheet you are using, in my case 3/16". After returning from my sabbatical and after the new year rolled over I began spending time at the San Jose TechShop where I discovered all the awesome tools that can bring musings like mine out of your head and into the real world. This should then be screwed on to the 1/2" threaded rod and the tripod head finally attached to this adapter. It Now join the circles with tangential lines. This stems from trying to set up my 10" Meade LX200 for astrophotography. which act as adjustable brakes (or clutches) to tighten the Now that the gear parameters have been determined we need to use AudoDesk Inventor (2012) or an equivalent CAD solution to design them.
