Theres a site for I found for mods for the gso scopes. Their selling them and they also have a link for gso dob mods. Dont know the link but the company was dba astronomy or db astronomy.I only buzzed through it quickly but there was suggestions on improving the dob's movement by using felt to firm up the movement. Do a search or if I find the link I'll let you know.They were selling the scopes as a brand called Hardin.
