There's a lot of talk and little workshop here.
I know nothing about gear streangth, I have never broken a gear -
unitl today.
Feeling the only way to settle this is to actually test it:
1) I took a z16 gear and boiled it in five minutes, I live at an
altitude of aprox. 200 meter above sea level so the water should have
been around 100 degrees Celcius.
2) I put the gear in cold water
3) I could see no changes on the gear
4) I made a device alowing me to put a lot of stress on the gear
meshing with another z16 picked at random in my collection
5) After a few turns (got a soft axle) a "snap" was heard and there
was pieces falling... from the non-boiled gear!
6) I repeted the test and the non-boiled gear gave in after half a
twist.
7) Another try, this time moving the doped (boiled) gear to the other
position in the device, just to make sure there was no difference in
where the gear was. And again the non-boiled gear broke.
At this stage, when the doped gear hold for three non-doped gears I
thougth it was enough. Of course I should have boiled three gears and
made sure there was no difference there but...

| (...) <snip> Tobbe, Was there any noticeable deformation of the boiled gear? For example, did it have any out-of-roundness (i.e. ovalization) and/or was it warped? Thanks, TJ (22 years ago, 5-Mar-02, to lugnet.technic)

| Wow ! Interesting results. I would have bet my firstborn that it would weaken them. Anyone else try this ? I might just to see if Tobbe's result is a fluke... (22 years ago, 6-Mar-02, to lugnet.technic)
