- Help w/ repairing/refurbishing an equatorial mount - Physics ForumsMy eq mount was not behaving - the RA joint was slipping in its socket. There was too much play. So I repaired it once, tightening the axial bolt. The problem is that if I tighten it too much, it binds. So I've taken it apart a second (actually, third) time and cleaned it and regreased it. And...
