As promised the solution to my fixing problem #884 to ETX.

ETX can not be fixed on Tripod #884
It is not possible to fix solidly the ETX on tripod #884. I think that
the fixing screws are not correctly assembled that means the threaded
axes going in the knob of the fixing assembly is not far enough lowered
down into the black knob body.

The consequence was that even if the fixing crews where fully turned in
I could still move the ETX up and down about 2 to 3 mm in polar mount
this is not acceptable. The spring clips are stopping the screws going
further into the ETX base in my case the distance from spring clip to
surface fixing knop is to large, 3 to 4 mm.

The problem is solved in the following way; I took the screw assemble
apart by removing the spring clip, washer and spring, unscrewed the
fixing assembly from the tripod base plate, it has the same thread as
the ETX base and put a hard plastic washer between the tripod base plate
and the knob of the fixing screw. The diameter of this washer is not
very important but should be close to the diameter of the fixing screw
my washer is 4 mm thick the hole for the fixing threaded axis is 6.5 mm.

Now the problem does not exist anymore the ETX is solidly fixed now.

If you do have this problem in solidly fixing the ETX on the #884 tripod
do not bother your are ok with your ETX.

Have fun Henrik
