[time-nuts] Hydrogen Maser KIT! Update #1

[Mark Sims]

BTW,  be careful with micronized teflon...  it is a very powerful "oxidizer" and forms highly combustible/explosive/nasty mixtures with things like powdered or finely divided metals.  Particularly magnesium, aluminum, and titanium.   More than one machinist has been surprised by exploding swarf.  Magnesium/teflon "thermite" has three times the heat output per gram than iron oxide/aluminum plus releases HF on ignition.
