PE analysis (based on 10 minutes measurement session) is attached.

The whole thing turned out not too bad, considering that the alignment was pretty much "ad oculos" (visible trend in PE).
Also, later I realised the worm gear meshing was not done properly (too much backlash).
Lapping may help to drastically reduce the PE even further, as shown on the graph done by Filip Lolic - he started from similar PE as mine but ended up with 1/4 of the value, after treatment with the diamond paste (0.5um, http://www.zvjezdarnica.com/forum/in...ach=7183;image. The details of his work can be found on EQMOD Yahoo group).
Also, I still have original bearings - it is not clear the new bearings will help, according to articles posted on EQMOD group (http://f1.grp.yahoofs.com/v1/kPATTXv...eplacement.pdf)
