[ATM] Polishing question
Good morning all,
I have a question in regards to polishing on my 6F6 Mirror.
I've completed fine grinding and poured the lap. I built the tool with
Gugolz 64. I think there is a good amount of CEO embedded in the pitch.
The channels are pretty clear at 1/4 inch. So this morning I did a cold
press (to fulfill the required oath in Mike Lockwood's figuring notes)
with an ambient temperature of ~80F for about 40 minutes (arguably a
"warm" press I guess 8-). I also pressed with a some tulle for micro
faceting.
I did some polish strokes and found the process to be what I would
describe as "heavy". I would contrast this to the fine grinding with the
tile tool and WAO. The fine grinding was very light and easy. I only
needed light finger pressure. I did not need cleats to hold the mirror
or tool in place. However, with the lap I needed to cleat the mirror and
I needed a good hold on the top disk to move the disk. I did not feel
slipping and grabbing. I would say the heaviness was uniform regardless
of offset or rotation. Adding and removing water did not seem to change
the feel.
Does this "heaviness" to the process sound correct? Or is it possible
the pitch is too soft?
Thanks guys,
