Welcome

Where the 19th Century Art of Mirror Making Meets the 21st Century

The Saint Petersburg Mirror Lab is a small band of dedicated mirror grinders and telescope makers living in the Tampa Bay area of Florida. We offer a mirror making class for interested persons. We strive to create the best mirrors our home brew technology can muster. This includes robotic foucault testing and laser interferometry.

  The dob wrap is almost ready
2017-04-07
The transformation of the blank wrap to a masterpiece over about two hours was amazing. It will be
on the 10in dob soon.

  Rough Grinding a Honeycomb Mirror Blank
2016-11-10
Mike Davis has begun rough grinding another of his home made, honeycomb-back, light weight, mirror
blanks. Here he is using a couple of stacked barbell wights for the tool and 60 mesh silicon carbide
grit.

  Unusual Condiment Tray
2016-11-04
At the SPAC October picnic we used a 16 inch mirror as the condiment tray. It was recently started
with 60 grit and had about 80 thousandths of an inch of depth on it.

  3D Printed Focuser
2016-09-23
This is Tom Spano's 3D printed Crayford focuser. The white area was printed and it is internally
using a honeycombed design for strength.

  Paul with his finished dew heater controller
2015-09-03
Paul took a different approach and mounted the dew heater controller board from the lid of an Otter
box. This came out really nice. Great work Paul! Now all we need is a little dry air and clear
skies.

  Paul finished another mirror!

  Brent and Joey finished their 10 inch mirror
2015-06-06
Brent and Joey proudly display their amazingly well polished 10" f/5 mirror. it came in better than
1/6th wave with a Strehl of .93. Congratulations!

  Dimitri building a dew heater controller
2015-06-06
Dimitri (right), with a little help from Paul, built a dual channel dew heater controller at the lab
today. We should have seven of these keeping our telescopes dew free within a couple of weeks.
