[Craig.a.c (Craig)]

I came into the same problem that others have with stiff dob mounts.
After doing some searching on this site and reading how others have
corrected the problem, I decided to have a crack at it myself.
I cut up a milk bottle and made some, very crude, washers out of it (8 in total).
Now I can rotate it sideways with some, but very little friction. There is
enough friction to keep it from moving freely but easy enough make very
slight movements without having to push to hard and overshooting what I
want to look at.
Who would have thought that a plastic milk bottle would do the trick.
