(...) I measured the temp in my attic last summer and it reached 115 F. Needless to say I don't keep much up there and definitely not my Lego collection! ROSCO had a bad "melting" experience: (URL) think this was caused by prolonged exposure to (...) (23 years ago, 5-Mar-02, to lugnet.technic)

Plastic doesn't get stronger under heat-treatment. This type of heat treatment is used to control the crystallization of metals, and long-chain polymers like plastic just don't behave like that. If you need stronger gears, double them. It is the (...) (23 years ago, 5-Mar-02, to lugnet.technic)
