Bought 5, pounders, shot them all with my 50. Didn't have time to bleed them off individually. Am having a hard time finding all the pieces. Any suggestions? :D
I don't have any idea, but I would assume at least 100psi, and probably a lot more than that. I only use them as a non-pressurized gasoline tank, and not a pressure vessel. you may be able to look up what the maximum pressure propane can generate at a certain temperature, say 100 deg. F , and therefore the tank would have to withstand at least that much. I don't recommend using it as a pressure vessel though.
Good idea, I am nervous about messing with the propane cylinders, so I try to use the oxygen cylinders, though they have to be empty or they can act like a blow torch when you cut them with a grinder!
the few times I have had to do this (I make sure it's empty and bled) I do that first cut or drilling in water. I figured if the tank is say full of lpg and it punch a hot bit threw with no air around it can't burn. I don't know just throwing my 2 cent in.
+Mr3wheeledbike Hey, thanks for the idea, drilling under water is an excellent idea! I let the tank sit outside for a week with the torch attached, and the valve open. Then I unscrew the torch, and push in the "tire" valve with a small screw driver (while wearing gloves and a face shield, and NO flames nearby!) If that all goes well, no hissing etc., I then drill the 1/8" hole in the side, and let it sit a day or so. After that it should just be a piece of steel!
+Mr3wheeledbike I just added your under water drilling idea as an annotation onto the vid, so I wanted to give you credit for the idea! I will finally make a vid showing how large a Deltic engine is, hope you like it, and I hope my permanent markers are up for the task!!! :) I am still working on the ultra mini Compound Deltic, it is taking me a long time to get the little sucker right! I even contacted the Deltic Preservation Society ( DPS ) with a question about it :)
ChargerMiles007 hey thanks for that bit of credit but feel free to use any idea i have any time. As for the deltic news, that great! I want to start the project in about 2 years time (will have my own shop then) but i sure it will take a long to to finish if i cant even mange to figure it out. I think the key in in using the right base engine flat head engines are promising but lack the open deck format i am looking for.
+Mr3wheeledbike I started the full scale Deltic layout yesterday, I am about 5 hours in now, but it should look decent when I am done. Vid to follow. :)
I like to shoot the top area of the tank to make sure they're empty of everything. Ive had a few fly a few feet, but they dont explode, a hole is just made. Much quicker, and if youre a good shot, you can do it from a distance for increased safety. I used to do this on the larger propane tanks when Id scrap em. Id shoot the valve on those while they were chained to a tree.
+Jon Woods Hmmm, interesting ideas! Personally I wouldn't dare to mess with one of the 20 pound tanks, but I have heard that some people do. I know someone who used to unscrew the valve off of the tank, after the valve had been left open for a few days. He said he still got a whosh out of it when he held a torch to the opening. Apparently the propane seeps into the steel tank walls, and takes its sweet time coming out.
ChargerMiles007 correct load of accidents with steel drums happen because of this effect just opening it for a while wont get rid of al the gas and with some gasses damn its not just a whoosh xD
+Travis Tomlin I just uploaded the vid where I actually build the tank, it is rather long, but it requires a bunch of steps to build a tank. As I mention, Safety is the #1 priority, so I recommend using the empty oxygen tank, less hastle.
+Travis Tomlin Yes, I have a bunch also form a little outdoor Bar B Q, though I found the shorter "fatty" tanks to be a bit weak. They might work OK if you left them in 1 piece and mounted it horizontally for a large 8 horse engine or say for a mini bike. I think you would need a gas fed MIG welder, or TIG so you didn't blow too many holes in it while welding. Probably best to hold the tank with band straps like the old tanks at the end of vid 2.

Just fill the tank with water and go ahead and cut it then it will leak out some water but there is no gas left to ignite

Get out some powerful magnets!!! :)
How many PSI does the 1pound tank withstand as a maximum?

Great video you should make a video of makeing a gas tank out of a portable air tank
I remove the 2 valves the main on the top and the one on the side and blow some air in to it to move all left over gas.

Good point i've got a bunch of those gas cylinders.

Drill it in a pan under water.
Yes, I can see how that would work! Thanks
good idea

Yeah we have a ton of empty tanks because we used them on our plow when the fluid would free last winter
