(...) This sounds like the basic technique for "tempering". You've probably heard of tempered glass or tempered metal. From what I remember, this just changes the way the strength is handled in the material. A normal material bends more instead of (...) (23 years ago, 5-Mar-02, to lugnet.technic)

I'm going to throw in my "dos centavos". FOR LEGO SAKE! This "MODEL OF THE MONTH" feces (putting nicely) is getting to be about as bad as those dorkheads who couldn't agree wether the 21st century began in 2000 or 2001! This "whatever of the (...) (23 years ago, 5-Mar-02, to lugnet.technic)

(...) Well Tobbe, When I started on rec.toys.lego (actually, it was alt.toys.lego) Joe Lauher had a Model of the Month segment where he'd pick a cool set and write about it: (URL) began in 1994 and ended in 1997. Obviously I'm not to judge what (...) (23 years ago, 5-Mar-02, to lugnet.technic)

(...) I tried cleaning Lego in boiling water once - it discolours and warps. (actually, it was Duplo - bought at a garage sale and being sterilized for the kids, but I have no reason to believe it's made from a different plastic) Matthias Jetleb (23 years ago, 5-Mar-02, to lugnet.technic)

(...) A quick search on Google shows that ABS (Acrylonitrile-butad...e-styrene) has a melting point of 103-128°C. Since water boils at 100°C, I don't have any doubt that you would see some deformation by that point. -- David Schilling (23 years ago, 5-Mar-02, to lugnet.technic)

I recently received an email from someone about strengthening gears. This person claims that by boiling the gears and then cooling them with cold water, their strength will increase. Has anyone tried this? What were your results? TJ (23 years ago, 5-Mar-02, to lugnet.technic, lugnet.robotics)
