@rasterweb@mastodon.socialI did a silicone casting today and I usually wave a propane torch flame over it to help get rid of any bubbles... This time I tried to turn the torch off and it just... kept shooting flames! 
I grabbed a pair of pliers and cranked on the knob but it kept spitting fire. I ended up disconnecting it.
It might be time to get a new torch. (This one is probably 40+ years old as it belonged to my father.)
@djsundog Whenever flames are shooting out of something and I cannot stop it I start to question my life choices...
@rasterweb it is worthy of a moment of pause and reflection for sure heh
@rasterweb I love using old stuff of my dad's. Probably old stuff in general, but it's hard to let go of pieces like that. Safety calls the shots on this one though. Be safe.
@rasterweb I’ve seen this before and I always assumed it was because I was using it with the bottle inverted which leads to getting some liquid propane in the tube above the valve. As soon as that evaporates, the flame will stop. Of course my torch is also 40+ years old 
@rasterweb Could just need a disassemble, clean, reassemble? May find the valves or valve seats are a bit worn, or there is an o-ring in need of replacement.
@cefiar I looked at and thought “Wait, isn’t there an o ring!?” So there’s a chance it fell out or deteriorated.
@rasterweb Some vales don't really have any o-rings (maybe a gland, but usually not in the path of the gas). If the valve itself screws in place, you might be able to simply buy a suitable replacement and keep the rest of the torch intact.
@rasterweb That would have made a hell of a youtube video if you had been recording
