[QUOTE="Captain Jack, post: 854381, member: 243342"] More updates. Received my heavy duty 24" jack - dear Lord, it's huge! It's bigger and heavier than the 36" one. There was a problem with it missing the counts though - I had to adjust the reed sensor inside to make it see every pulse. Even with that, it seems to be miscounting as it lands a bit short of the stored position. I am pretty sure it's to do with pretty tight ball bearing thing on the main bracket, which I am having trouble loosening, so I put my 36" back on. Will see if I can loosen it but the 36" one is doing the job OK. Why don't these ball bearings not arrive already greased up and loose on new jacks?! More things... Decided that my threaded bar for the declination adjustment was giving me a little play at extremes so I bought some spherical bearings as well as needle bearings. The needle bearings arrived first, so I put those in place of the threaded bar and put a steel tube through that, tightened by normal M8 bolts. The result is a very smooth, play-free movement. Happy with that. [ATTACH]57485[/ATTACH] [ATTACH]57486[/ATTACH] [ATTACH]57487[/ATTACH] Next - C band LNB polariser plate construction and a cover. [/QUOTE]
