Polishing Is
Fun!
Hello again!
Here comes some ATM Mirror
Porn. Some people may find some of the
images offensive, but I think they are beautiful and a work of art in progress.
When we last left off, I had
poured my pitch lap, did two hours polishing on each mirror, built my Foucault
tester, and did some LED tests to see which was color was best. As far as color goes, its becoming clear
that white or blue seem to be the best colors of choice.
When you first start polishing,
it’s VERY rewarding! After just a
couple hours, your dull frosty mirrors SHINE!
Just don’t get too excited and start to believe you’ll be ready to ship
those mirrors out for coating any time soon J
To date (April 5, 2001) I have
completed 8 hours of polishing on each mirror, using the same pitch lap. That’s a total of 16 hours polishing glass,
and I guestimate that I am perhaps 50% completed with polishing, maybe a little
more.
My current polishing regime is
MOT, Mirror A 8 Laps around the barrel then Mirror B for another 8 laps. I do this for 4 hours, and then acquire some
mirror images and call it a day.
My loving and compassionate wife
asked if I wanted to come inside and polish! So now you will find me in the
living room, polishing atop an old speaker cabinet that must way 70 lbs or
more! The only downside is she gets to
run the Remote for the TV J On the plus side; she
was kind enough not to force “Judge Judy” onto me J (God I love this
woman!)
Enough Chatting Time for the
“NAKED MIRROR ATM PORN”!!!!!
Below is are 2 charts of images,
one for each mirror. From left to right
is polishing in increments of 2 hours.
Included in the far right hand columns are links to Animated images. I’ve included Windows AVI files as well as
conventional animated GIF files. The
AVI files are substantially smaller than the GIFs.
My advice would be to check out
the animations on Mirror B first, as they seem to be the most interesting to
watch J Enjoy, and any feedback is appreciated! Also see the polishing notes underneath the
frame!

Hourly Polishing Notes
Two Hour Polishing Notes
- Stroke: 2/3 Center over center MOT (oops…)
- Boy are those some ugly mirrors
- DON’T use rubber cleats, they heat up the glass and cause
deformations!
- Center of mirror focuses longer than edge by 0.300 Inch
Four Hour Polishing Notes
- Stroke: 1/3 Center over Center MOT
- Finally got a white LED to test, looks kind of purple to me
- Scratches are greatly reduced J
- Center of mirror focuses longer then edge by 0.250 Inch, Making
progress!
Six Hour Polishing Notes
- Stroke: 1/3 Center over Center MOT
- Finally starting to look smooth
- still have some flaws near the edges of the mirrors
- Center of mirror focuses longer than edge by 0.200 inch.
Eight Hour Polishing Notes
- Stroke: 1/3 Center over Center MOT
- Center of mirrors are still a little frosty looking,
- Got a ronchi Grating to play with J
- Ground down the end of the LEDs flat. This reduced excessive light from screwing with the camera,
but left funny looking vertical lines on the images. Need to smooth off the face of the led
with some fine emery cloth..
- Center still focuses longer than edge, but now down to 0.125
inch.
- Ronchi Video is pretty cool J
- Perhaps its time to start a parabalizing stroke to knock the
center down a little quicker?
Hmmmmmmm
