Azimuth upgrade

The pieces were not as refined as I expected. Very rough cut and could rub the edges and get particles to come off, make me wonder how long they will last. Expected to be polished for the price. Does not move very easily when focused in on higher power lenses, but at least I can dial the focuser without it moving the scope out of alignment with my view.

Smooth!

Installed this kit on my Apertura AD10. Significant improvement over the Lazy Susan due to the pads being close to the outer edge of the base, eliminating any wobble that was there before.

Farpoint Azinuth Upgrade kit

As always with Farpoint,,super fast transaction and shipping. And I am 100% satisfied with the azimuth upgrade kit for my Z12 dobsonian,,a perfect fit and very smooth functionality. A huge upgrade from the stock pin roller bearings.

Farpoint Upgrade Kit - Zhumell GSO Azimuth greatly improves the stability and function of the telescope base. Provides much smoother and consistent movements, eliminating the troublesome rocking of the ground board.

Farpoint Upgrade Kit - Zhumell GSO Azimuth greatly improves the stability and function of the telescope base. Provides much smoother and consistent movements, eliminating the troublesome rocking of the ground board.

The stock Zhumell azimuth bearing (and that of many other Guan Sheng Dobsonians) is designed around a central “wagon wheel” with embedded needle bearings sandwiched between two metal disks. There are two problems with this design. First, the needle bearings have very little friction; they are much too loose. Even with the maximum tension on the adjustment knob, the telescope creeps from the desired azimuth with the slightest touch or breeze.

Second, there is no support or contact for the outside edge (rim) of the baseboard upon the ground board. This results in rocking of the baseboard. Most other Dobsonians have Teflon pads or some other support directly over the feet of the ground board. This is exactly where the support should be. In a properly designed Dobsonian, the weight of the baseboard is supported in the middle, but also (importantly) directly over the feet so that the weight of the baseboard is transferred through the ground board directly to the feet. The middle of the baseboard and the edge of the baseboard are both fully supported. Any possible “rocking” of the baseboard is eliminated. Unfortunately, this is not so with Zhumell’s “wagon wheel” design.

These problems are completely eliminated with Farpoint’s easy to install Azimuth Upgrade Kit. Once installed, the weight of the base board is supported by a central Teflon pad and three outer Teflon pads positioned directly over the ground board feet. The result is smooth and positive azimuth movement and much greater stability!

Compatible with Zhumell Z8, Z10, and Z12 telescopes and many other Guan Sheng Dobsonians.
