well ive sen a few vids on the net and im wondering how you do yours



thoe not the best idea to have a fag in your gob



both of these illustrate a problem with valve removal so how do you do yours

ive today cut the top of around the valve stuck a crow bar in bottom of the bottle and stilsons on the valve one foot on the bottle a bit of support and banged hard upon the stilsons handle and after a few stamps the valve started to come off

however they dont come off sometimes breaking the valve ive seen drilling into the valve or via the video above so what ways do you suggest ?

I have just degasses two bottles. After discussing this with Bezman and DKwelder. On the first bottle I could not get the valve off, so I used a hack saw to cut it off. As the valve is brass it will not give off sparks. This left a small hole to fill with water. The second valve came off with the help of a friend. Then I left filled it with water and left it for a couple of days. Using a cordless drill I drilled a hole in the top 5" from the valve and the water flowed out. Tipping the tank I emptied the water out a bit more. Then I cut a large hole with an angle grinder. There were no flames or anything else exciting!  :) 
Hope this is of help

James,

Glad to hear of your Success!  Very Happy cheers  None Excitement, in a task such as your, is a good thing. Very Happy

One good piece of added safety info to pass on with this would be. 100 repeated successfully Bombs defused, does not guarantee that tank No. 101, wont leave you wondering what you did wrong this time ?  

Repetition of a task safely, does not always guarantee ones own personal safety for the next time. :evil:

ive just done 3 today degassed 2 before and added washing up liquid on a second fill of water the third bottle give me some trouble as i broke a little of the valve while trying to remove it i left that for a couple of weeks airing off until today was fine lit a piece of paper there was no flame at end after removing valve

cut all 3 of them using a stainless steel thin blade as gives off less sparks one big bottle into 2 halves and the other 15kg took the tops off them so gives me a 28" rocket height the other gives 2 24/26" height on that one

one ive already cut for the burn tube to slot into

I have never been one for spending much time in front of a TV,  :shock:  This first video  made me think of a program I once seen on Spike TV.

Safety is not a joking matter,and should not be taken lightly. Everyone is responsible for their own personal safety, I guess there will always be those people who feel differently! :sleep:

I would suggest you develop a good relationship with your local scrap yard. I get all my bottles from them with the valves already removed. When I've got a project coming up, I just ask them to keep an eye out for the size bottles I need and they call me when they've got some. They remove the valves and keep the brass, I get the rest really cheap.

I fill them up with water and pour it out. Once is really all it takes, though if you do it more times than that you can eventually get rid of the smell.
