Re: Banebots 42mm gearbox: Recommendations for use
Update: After tempering at 300C for 30 minutes, the new hardness numbers are:

HRC 49.5, 49.5 (~230 ksi tensile yield)

So it's still about twice the original hardness. I'm putting it back in the gearbox tonight and we'll test it a bunch. I'd still like to get some spares since this one has now been drilled/poked/prodded/baked/cooled/etc. If anyone from BaneBots is reading - selling these individually would be very helpful for the time being until a more permanent solution can be found.

Regarding the pins, all I can tell you is that they didn't fall out. I'll check them again after testing.

In summary:
- annealed at 900C for 15 minutes
- quenched in water
- tempered at 300C for 30 minutes
- quenched in water
roughly doubles the hardness for the 42mm carrier plate. How this applies to the 56mm plate is still uncertain because it is apparently made of a different steel.
