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" or 1/2" 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 for the 3/8" bolt and 5/8" through hole for the 1/2" bolt.  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 PTFE bearing thickness of 3/16".  The 1/2" bolt kit is recommended for 20" and larger telescopes.
