 | | SNOT - What's the commotion about?
|
|
I've heard many builders incorporate the SNOT method into their creations. As far as I can tell this means that the Lego piece is turned on its side or upside down. Am I missing something because this does not seem impressive to me at all. What's (...) (23 years ago, 5-Mar-02, to lugnet.technic)

The "service" temperature is the limit at what you should operate it at. The "mold" temperature is how LOW the mold has to be cooled to get a good shot. The "processing" temperature is the temperature the plastic has to be when it enters the mold. (...) (23 years ago, 5-Mar-02, to lugnet.technic)

I have never broken a gear. But then, I am a mechanical engineer; I am nice to my gears. But I fry a lot of electronics! My experience is that the torsional stiffness of the axles is the limiting factor of high-torque designs. I have permanently (...) (23 years ago, 5-Mar-02, to lugnet.technic)

If you would just put your bricks in the kitchen oven you would make rapid progress with this question. Better yet, obtain a laboratory hot plate with fine temperature control and put a brick between two slides with a weight on top. Do this at (...) (23 years ago, 5-Mar-02, to lugnet.technic)
