Thomas, I have to say this is a first class tip.  After only about 7 long
wets with 220 Alox.  I decided to wash up and examine the surface with a
25mm eyepiece.  I sprinkled a few grains of the 220 on the mirror and then
began examining.  I was thrilled to find that I couldnt find a single pit
larger than the grains of 220 alox.  Without this tip I would have been
grinding away for hours not realising I was already done.

I think my mistake was not realising just how much the 25mm eyepiece
magnifys.  What I was actually looking at were the pits from the current
grit and not from the preceding grit as I had thought.

I was also pleased with the results of a sharpie test which seems to show I
have good contact between the mirror and tool.  At this rate I'll be
polishing by the weekend:)

No doubt I'll be back making myself look silly again soon but until then
thanks very much.

Clear skies,

Dave.
