[hank pronk]

Brian,
How thick is your acrylic?  should take more than a night?

Yes, I have the annealing schedules.  I have an electric oven and two digital thermometers, one I'm going to put in a piece of acrylic and the other one I'm going to use to monitor the oven temperature itself .  I'm worried that the thermometer in the acrylic won't register until it gets heated throughout, and so then the oven temp might go higher than it should.  So between the two readouts I can heat it gradually up.  It'll be a long night.

Brian,
Are you going to anneal your windows yourself?

Used my polarized lenses on the newly cut piece and it appears clouded throughout the whole piece.  Where as another piece I have, you can clearly see a stress area around where it has been drilled.

annealing acrylic 
  
I'm planning on annealing my viewports,  does anyone
know if the acrylic from the factory is pre-shrunk ?
