Morning All,
        I've just completed the 2nd session today with increased weight on the
overarm. The first sessions ronchis and foucault are at the link in my
signature. These were taken 5 minutes or so after finishing the session.
The next session started straight away. I will put those on the web as well
once the blank has properly acclimatised. Several hours or so. At Dennis's
suggestion I have increased the weight on the overarm to 3.75kgs from
1.25kgs. The lines are finally starting to diverge. With the polishing
sessions, is it ok to test straight and then do the next session of
polishing without doing another pressing? Any suggestions on the stroke or
the star lap?

Cheers
