Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. The most common scuba diving tank on the market today is the aluminum 80. It is the most used tank in the scuba diving world. Scuba tanks come in two kinds. They are either made of aluminum or steel. Steel tanks cost more but are physically smaller and slightly lighter than their aluminum counterparts.
You should look up propane tank hang drums (or Hank drums) on Youtube. They are a different type design where...tabs, I guess is the best word, are cut into an old propane tank and vibrate when hit with mallets or a hand. They're similar to xylophones and the like in that respect - stiff surfaces connected at one end (embedded cantilever-type). You might enjoy making one, and there are lots of fantastic instructions online - I think it would nicely complement this tank instrument.
This is a very cool build, by the way. If I ever come across an old scuba tank, I'd like to build one. My folks' garden is filled with windchimes and gong-type instruments - I've always loved these types of things.

FIRST ROW
GOVERNMENT APPROVAL
First set of letters either DOT or DOT/CTC. These stand for US Department of transportation and the Canadian Transportation Commission. If you travel to Canada and take tanks across the boarder, make sure it has this CTC marking on it. Most tanks sold in the US have the DOT stamp on it.
METAL TYPE
Next set of letters tell what type metal the tank is made from. The 3A denotes carbon steel. Used for early tanks. This tank more prone to corrosion than chrome steel of aluminum.
The 3AA stands for chrome-molybdenum steel. It appears on virtually all steel tanks today.
Aluminum cylinders may bear the designations SP6498, E6498, or most times it is 3AL. First two designations identify permit numbers under which aluminum cylinders are manufactured. But the 3AL is the usual mark you will see on tanks manufactured in the US after July 1, 1982.
WORKING PRESSURE
The next set of numbers, usually four, is the working pressure of the tank. This is expressed in pounds-per-square inch. The cylinder should not be filled past this point. The single exception to this is when you see a + sign at the end of the second row or next to this pressure. That plus sign is usually assigned to steel tank and means you can fill by 10% increase. Most aluminum tanks go to 3000 psi, a few go to 3300 psi. You need to look at this to see what your tank is rated at. Of course the dive shop you take you tanks to will look at this number.
SERIAL NUMBERS
Some tanks have a second row while others may have more. All tanks have an unique number assigned to them to identify the tank, this is the serial number. May represent the size and lot number.
MANUFACTURER IDENTIFICATION
This usually follows the serial number and describes the dealer who made the tank. PST is Pressed Steel Company, Luxfer, and Kidde are the common.

HYDROSTATIC DATE
The cylinders initial date follows the manufacturer name. It consist of numbers representing month and year that the cylinder was tested. These numbers will be separated by the hydrostatic tester's initials or a special symbol that the tested had registered with the DOT. Each tank needs to be re-tested every 5 years. Each 5 year test date will appear somewhere at the top around the neck.
This is a brief explanation of tank markings. Like I mentioned above, ask you local dive shop to help you determine what your specific markings mean.
