(...) I am guessing that your compressor is stalling out before you get enough pressure. The pressure in the compressor is high enough to react the torque of the motor. The fact that you have better results using one cylinder instead of two supports (...) (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)

In lugnet.technic, David Schilling writes: <snip> (...) single piece by itself will deform. If you handle it carefully (i.e. don't squeeze it hard by picking it out of the boiling water with tongs), it may not deform. But then I don't know at what (...) (23 years ago, 5-Mar-02, to lugnet.technic)

(...) I don't think I'd want to try this. There's a reason that LEGO recommends washing the parts only in *warm* water: if you used hot water, the plastic will start to deform. Some instructions specifically state this. For example: (URL) David (...) (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)
