Details
This is one of the key components in making a Dobsonian move smoothly and easily in azimuth, even when pointed near the zenith. Each kit contains a 3/8" x 2.5" brass bolt, Bronze thrust bushing, stainless steel locknut assembly and full instructions. The new bushing only requires a 1/2" through hole. The supplied bolt length is configured for a nominal rocker box bottom thickness of 3/4" and a ground board thickness of 3/4" and a teflon bearing thickness of 3/16".
The 1.50" square Teflon center pad is shimmed to take part of the load off the azimuth pads, giving the telescope excellent azimuth movement. The pivot bolt is pre-drilled with lock screw for digital setting circles. Optional bolt lengths available are 2", 3" and 3.5". Add $5 for one of these custom lengths.
