Thread: What I did this weekend.. part 2
If there was gas still trapped in the bottle then an explosion would have occured immediatly we remove the bottles valve because the air would have ignited the remaining contents,this bottle has remained in an open state in the back yard since I first mentioned about making a furnace on this very forum two months ago?.
Anyway, Irving could you feast your eyes over this torch and give it your expertise as to whether a better one could be had?

Rubbish George... the air would not ignite anything... the mixture of oxygen and propane at 20:1 is highly explosive but wont explode unless its ignited.. by a spark.. its whats known as an explosive atmosphere... the point is that opening the valve will not replace any remaining gas in the cylinder ... gas travels from a higher pressure to a lower one... once its reached atmospheric the flow stops leaving traces of propane in the cylinder unless flushed out by something...
you were just lucky... others might not be...

Personally i feel that Georges post wants deleting on safety grounds alone, never mind about anything else.

I have moderated this thread, John please refrain from attacking people directly like you did.
George, first warning and an infraction served.
George, it’s not up for discussion. We have said all that needs to be said in our previous correspondence to you weeks ago, this is another classic example of what we stressed to you, only this time, its on a topic, that could be very dangerous to others!

Irving your burner does not need to be that elaborate. I have been running my furnace for just over a year now mainly to feed my habit of needing large blocks of ali to mill. I first went for an all singing converted torch head. these days i have a length of 6mm tube with a 0.6 welding tip soldered in the end which sits in front of a 20mm tube into the furnace. i can adjust the the tip in and out propped up by bricks etc etc. It's cheap, works wel, i do not need a blower and save a shed load of build time. I keep meaning to tidy it up but what the heck it works.If the nagging gets really bad......Get a bigger shed:naughty:
forgot...i can melt bronze and brass mixes tooIf the nagging gets really bad......Get a bigger shed:naughty:
