[TheForge] Sodium filled valves

[Peter Fels & Phoebe Palmer]

Ron;
I've cut what i guess to be, one kind of sodium filled valves, with a 
chop saw ,without dire consequences, and used the stems for punches OK.
Wouldn't try to cut them with a torch or hot cut them for sure,
But i'm not certain enough to say it's OK...pf
