My point is not to sit on an acetylene bottle that has started to warm up because it has turned a bit cold outside :lol:

Oh, well no. I wouldn't sit on one either. They're not very comfortable anyway, with those fittings and gauges sticking
out the top. Bit hard on the bum, and your other naughty bits.

Once you get the naughty bits out of your bum! :bugeye: you can go use this link to find out things your mum never mentioned about acetylene.
American Miners Carbide Lamps: A Collector's Guide to American Carbide Mine Lighting
by Gregg Clemmer
The current prices on US Amazon are way over the top :doh: or I was really lucky :thumbup:
If you are interested self generation of acetylene and the equipment, for place that it is impossible to exchange cylinders there all kinds of companies on the net producing them google them 206,000 hits

I've had an odd project in mind for some time and not the knowledge to produce the desired effect.... This thread has now enlightened me (I know ::) ) to the possibilities of the projects fruition.
Basically.... once I get my ar*e in gear I'll have a hopefully interesting post to erm... Post!
Already found 3 sites with schematic and dismantling pictures/procedures of these lamps :thumbup: (links can be provided if you want them?)
I'll not be the first on here to make one I'm sure.... But mine will hopefully be a little different :loco:

Let me have a guess - you're going to try make a carbide lamp to match the keyring torches in your signature?

As a carbide caver in my younger days. And having had a number of the lamps both old ones and the more just modern Justrite brand . Don't know if your internet info, mentions the two most important things after having a gastite seal between the carbide chamber/gas compartment. A lot of people would lose the rubber gasket and the gas would leak out and catch on fire when it was on the hard hat/helmet. Since it wasn't under much or any pressure it was a lazy type flame. Interesting to see none the less and the persons reaction, 3 hours in a cave! :doh:
Have a positive water drip shut off, so it will stop generating gas.
DO NOT use any form of clamping device if you use a hose from the lamp unit to the generating unit if they are separate as a belt generator unit. That way if you generate more gas that you use it can blow the hose off before the pressure gets to an unstable number.
As it is 15psig in the atmosphere, that is the unstable point.
Here in the US they were also favored for nighttime hunting of raccoons. Union carbide was the largest manufacture and seller of the carbide. In rural areas you could find it at almost any hardware store in years past.
Also on an environmental note, the spent carbide after it has generated acetylene gas,turns into a sticky powder while wet. It is considered a toxic/hazardous material. Be careful were and how you dispose of it.
It will kill wild life and pets, and water life if it gets into a stream or pond.
Plus clean it out of your generator section when you recharge the unit. It is a royal pain to remove after it dries and can after time be corrosive to the canisters.
As you have probably found out, googling carbide lamps will bring up a skip load of hits. I have to see if I have any photos of the lamps and the inside working end of them.
