Third try isn't exactly charming, but it's lookin' a lot more presentable!

Several lessons learned:

Don't pay the site in the link above much attention when it comes to time/temperature . . .

. . . 250°F/longer heating time should work better for 1/8" clear plexi . . .

. . . 300°F still caused a few bubbles to boil up in the plexi, but none nearly as bad as having a dead pixel . . .

. . . when using empty cans in an oven to hold up the frame . . . remove the paper first . . .

. . . it may not be Fahrenheit 451, but 300°F will squeeze some smoke outta can labels for the first couple of minutes! :O

We knew this already from a link posted earlier: thinner material should be used to form a "Plexi CRT Face" for an LCD . . .

. . . but I'm trying to tweak the process for making a MacQuarium Face. }:)

Pics of the plexi inside the ZipPlus sometime tomorrow evening.

Gotta get to bed . . . this MON-TUE "weekend" has drawn to a close and 7AM is "Monday morning" in my work life. :p
