Hi Brian. Yes, there's two annealing processes required. At 3 inches
thick by 24 inch dia. for my main view port, it looks like it may take up
to 4 days for one annealing treatment. ( from a little preliminary research done
last winter )
I didn't find any set formula for shrinkage back then, but I
didn't spend a lot of time looking either.
My smaller windows are 2 inch thick and the disks are 16 inch
dia.
I have a machinist locally that advertises he cuts/machines plexi and said
he does "heat treating" but I didn't get a good feeling about his abilities.
(still looking ) and I wanted some info to help determine if the process
is being done right. Frank D. A Good Credit Score is 700 or Above. See yours in just 2 easy steps! |
