Re: dive tanks/hyrda testing
All we need is for the government to hire one university student to look for things they have missed. If we are found you can be they will try and regulate us. This happened in the industry I am in, marine in Canada. What a nightmare! They didn't understand what they were doing but they did not care, they are the government. Dan If our safety record wasn't as clean as it is I'm sure the goverment would direct much more attention (and restrictions) to our hobby. If a few restrictions eliminates just one accident it would probably be worth the hastle but until there's an on-going problem, I feel that we are better off being self regulated. > > Later, > Trent >
Re: dive tanks/hyrda testing
Hello Everyone, Although our fuel tanks have the potential to be extremely dangerous, SCUBA tanks are considered a life support item. This in itself induces a lot of goverment restrictions. I don't recommend the following procedure for our steamers but thought it an interesting way to hydro test a pressure vessel. A SCUBA tank hydro is done with actual air pressure, filling the tank to 5/3 of it's working pressure (5000 PSI!) for 30 minutes. When the pressure is released the tank must return to it's original diameter within 10 percent of it's maximum expansion during the test. Does that sound scary or what?! Wonder what the "pucker-factor" is in the hydro room where this is going on? Personally, I think that we have an excellent safety record for the simple reason that we tend to "over-build" our steamers. If our safety record wasn't as clean as it is I'm sure the goverment would direct much more attention (and restrictions) to our hobby. If a few restrictions eliminates just one accident it would probably be worth the hastle but until there's an on-going problem, I feel that we are better off being self regulated. Later, Trent
Re: dive tanks/hyrda testing
It does not work that way. It's pounds per square inch. If the pressure is 500psi and the surface of the inside of the vessel is 1/2 a square inch it only has 250lbs pushing on it. Plus you have now changed back to butane which we know is allot less pressure than propane. It was propane that started this thread. The shape is probably the most important aspect. Remember you can push on an egg if you push on the ends but try the side and see what happens. Why do you think boilers are round? It's not because locomotive builders could only find round pipe. If you believe that I'd like to see the original use of the piece of pipe the Big Boy or Daylight boilers were made from.

Re: dive tanks/hyrda testing
No we don't but if people are going to make heir own propane tanks I would change my mind and say yes, before they try them out around me. Dan > > I'm inclined to think that we are doing enough.

Re: dive tanks/hyrda testing
Walt and Lunk, You are a Lunkerforous old gentleman who always hits the nail on the head (probably with your head!!) So--Thankyou!! Lunkle Geoff. PS. According to reports, the Hekemian steamup was fantastic--I am so green with envy--hope we get photos! And my freind Bruce Price did a lot -A LOT -of the work on the construction. A friend you ask?? Well-- we exchanged "no-no" gauge locos and we are both very happy.!!!

Re: dive tanks/hyrda testing
In live steam,most clubs insist on hydra testing boilers for anything larger than gauge 1. I don't know if anyone does them. And since Trent brought up hydra testing of Scuba tanks, how about our Butane/propane tanks? Am I opening a can of worms here? Is it necessary? Or is our safety record good enough not to worry about it? I'm inclined to think that we are doing enough. We don't need any more regulations and rules to further complicate our lives. Or do we?

Re: Hekemian Steamup
Hi guys: It was a wonderful steamup. Three - 2 sided, 3 track, standup steaming bays fed the 48" turntable. Hundreds of feet of sidings/ladders/passing sidings, most filled with waiting trains. Barry Harper had his Coronation Train flashing by wide open, Bruce Price (the other live steamer who put inordinate hours into building the layout) had his Hudson with a 6 Leech car Empire Express highballing. It was a weekend for 20'-40' trains, passenger and freight, American and English models. At times 2 trains would run on one track. Grasshoppers, Stirlings, to American and French Mike's to Daylights broke the layout in. With a contingent from Ontario and Neil Rose from the UK it was truly an international meet. A good time was had by all. Jim Curry
Re: Hekemian Steamup
Walt, Would enjoy seeing photos of the Steamup. Do you know if anyone is likely to be putting pictures up that we can see ? Peter Trounce. -- > From: [EMAIL PROTECTED] > To: Multiple recipients of sslivesteam <[EMAIL PROTECTED]> > Subject: Hekemian Steamup > Date: Monday, September 11, 2000 8:44 PM
