[ATM] A bit of hand polishing advice please................
Morning All,
Last night I was able to cast the lap and get in two laps around the
barrel. The mirror is a 200mm 1240mm f/length (f6 ish) This is the first
session after the machine work. We decided to walk the barrel and try and
get rid of the raised central zone. At first the laps action was a bit
uneven but after a 1/2 lap or so it steadied and became a heavy consistent
dragging action. Around 1 - 2 seconds for a full forward and back motion. 12
strokes before rotating the mirror and tool. BTW The tool was on top. I
think a touch of tde is coming in. A slightly shorter stroke called for
perhaps?
