Introduction: Compressed Gas Cylinder Wind Chime

When I was a kid I used to travel with the carnival and always saw the kitschy stuff they sold on the independent midway. One of the things I remember was a large wind chime made from what looked like one of those big helium tanks.  I thought they were awesome! They had a deep rich tone that was almost like a buoy on the ocean.

When my Grandmother passed away for some reason my family kept her old oxygen tanks. Not those new aluminum ones the old iron ones.  When I picked it up and moved it it hit something and gonged....  I remembered my days at the fair and decided to see if I could make one.

This is the result! It turned out awesome and the clapper is heavy enough that it doesn't whip around a lot which gives you a nice gentle ring on blustery nights.


Step 1: Materials and Tools

You will need the following materials:

Cast Iron or steel gas cylinder  (I has an Oxygen tank, but, a co2 or helium tank would work also.)
5 feet of rope
Clapper  (I used a 1 pound weight, but a wooden clapper can be made to fit for a softer tone.)
Various nuts for retainers
6" x 24" x 1/8" "Hobby Board" (That's what they called it at home depot.)
Primer, paint and clear coat

Tools:

Metal cut-off saw or an angle grinder with a cutting blade
Jig Saw
Drill with a 3/4" bit
Table vice
Files (Bench grinder optional!)
Acetone
Rags
Metal coat hanger or a long piece of baling wire
Pliers


Step 2: Drain the Tank

Empty the cylinder.  In my case it was an old oxygen tank and from conception to actually doing the project it was a couple of months. I opened the valve to let it drain then put it off in a corner and left it for a while.  Just use a pair of pliers to open the valve.  At this point I was pretty sure all of the gas had dissipated so I was not too worried about the tank becoming a missile.

Also Oxygen is not flammable BY ITSELF...  It helps things burn better.  Better safe than sorry though so open the valve and leave it alone for a while!

Step 3: Remove the Valve Stem

For the first one I did I held the stem in a vice and used an oil filter wrench to turn the tank. 

Once the stem is out fill the tank with water to displace any remaining gas.

This time I just tried without the wrench and ended up breaking off the stem. DOH!  I ended up having to cut the stem off by just cutting the tank a little lower on the neck.



Step 4: Cut Off the Bottom

This is fairly straight forward, except the cutting blade wasn't large enough to do it in one clean cut.  I had to turn the tank and keep it all in line to finish my cut.

Start the cut a few inches up from the bottom to clear the indentation built into the bottom of the tank.

NOTE: This can be done with an angle grinder with a cut-off blade, but, be careful to keep your cut clean and straight! Or don't if you want a different look!



Step 5: Nobody Likes Filing, But, It Must Be Done!

Clean up our cuts now using a file.  A metal file not a wood one! I also used a bench grinder to make short work of the big bur left when cutting off the neck and the outside of the base.

Step 6: Clean, Primer and Paint!

So clean off your tank of all stickers and crap.  Mine had these plastic things that were held on by some new cosmic polymer.  Nothing soaking a rag or two in acetone and letting it soak into the stubborn stickers wouldn't take care of!

Next hang your tank with a piece of twine and a nut.  I had this handy dandy rack to dangle mine from!

Primer the snot out of it! Then pain the snot out of it!

Take your time here..  Light coats, try to get no drips.  If you look at the photos you'll see that the color is kind of patchy.  This was coat number two.

Step 7: Make the Wind Catcher

This part was just a bunch of eye-balling.  I used to cut off portion of the tank to make the curve. I eyeballed the point for the hole. Over all the length was about a foot.

A jig saw, a 3/4" (or diameter suitable to your rope) hole drilled and some sanding to clean up the edged and I have a wind catcher!

Step 8: Clear Coat

Next I strung the wind catcher and gave the whole thing several coats of clear gloss enamel.

Here is where I made a MAJOR error:  I thought that since the surface was dry the whole thing was dry.  It is not.  Leave this over night AT LEAST.  It would probably be better for a couple of days of curing.  I ended up with fingerprints and rag marks (trying to protect the finish) that required me leaving it for a day then sanding then another coat of color and another few coats of clear.

Step 9: Make the Guts

This was pretty straight forward. 

I will explain it LEFT TO RIGHT left being the "top".

I tied a knot about a foot and a half from the left end of the rope then slid a nut on to the left of the knot.  I used an old lug nut since the taper would center itself in the neck and give it a better hang.

I took it outside and held it up to the tank making another knot about 4 inches from the bottom of the tank.  If you go too high the rope will not have enough throw to allow the clapper to touch the sides before the rope contacts the lip of the chime.

From the right I slid on the clapper, a large retaining nut (the lug nut was too small by itself for the hole in the clapper) and then finally the lug nut.  Just a simple knot to hold everything in place.

AT THIS POINT GO TO BED OR FIND SOMETHING ELSE TO BUILD ON INSTRUCTABLES!

SERIOUSLY LET THE PAINT DRY!!!

Step 10: String the Chime

At this point I used a piece of baling wire to create a small hook and fish the clapper rope through the chime.

Just a simple loop in the top to hang it, then I tied the wind catcher to the bottom.  Trim the excess rope and use a lighter to melt and clean the ends of the rope.

Step 11: Hang It!

All that is left is to find a nice spot in the garden and enjoy it!

Thanks for taking a look guys! Let me know how yours turns out!

 Do you think you could do this with an old propane tank from a grill?

do not think of a fuel tank propane or acetylene it can and may change your life acetylene has a filler in it like sand and will retain the fuel forever the second you expose the inside of the tanks contents to the spark of a grinder....sawblade....spark from the motor of a drill or saw ,,,,,its all over ,,,,,,ask around if you have any idle thoughts ...all fuels are explosive , acetylene is unstable in pressures exceeding 15 psi (only the earth filler keeps it stable ) yes the tank pressure gague says 300 psi but ALL user end are red lined at 15 max....also it takes 24 of slow pumping to fill these tanks ck out you tube for some big flames ,,,,,,Last when you think you have an empty tank because you have opened it and no gas ----air -----co2 (fire extinguisher) comes out and you unscrew or take a Sawzall to the neck ,,,,only imagine the force and what happens to a tank unleashed ,,,,,,,,,when the dust clears and you still have eyesight …..you will find a still spinning tank covered in white ,,,,the frost is about a 1/2 " thick and you will need to go fetch some clean underware……….what can happen is as cutting the neck rust /debris has clogged the valve and the pressure has no way to get out until you cut or knock or try to shoot it …….Been there done that and its a sobering effect !!!!!!!! really of you can find a welding supplier who still hydros tanks ,,,,testing with a water filled tank so the tested one wont blow up see if he will sell you any old empty one that failed with valves removed ,,,,,but they to make great chimes gongs and drive the lil old lady next door nutz

I suppose you could, but, it would probably sound kind of tinny since the metal is so thin.

Provalve up pane tanks are so thin you get a nice resounding deep ring with steel tanks
HEY I almost bit the bullet ,,,,I opened valve up no gas excaped Good right NO NO NO NO I sawed thru the valve it flew accros a large shop bouncing around spinning like a pin ball machine finally began a clockwise spin lodging in a corner ……...it was snow white due to the rapid excaping of 2200 psi of co2 …….. it really made me think !!!! Rust had stopped the valve up …..ALSO DO not even think of an acyetlene tank ,,,,,they are filled with a diaomatacheous ????think spelled okay earth filler ….a fine dust ….that only way to get out is cut both ends off...I tried water hose from a fire truck ….also the thing that will K I L L YOU is the acetone ...yep very flammable liquid that keep s the whole thing from expoding . it takes 24 hrs to fill these if you lay one down give it several hours to assure all has settled ..one last bit the reason acytlene regulator is red lined at 15 # because any use over that it is VERY UNSTABLE,,,,,,,,only reason its 300#inside the tank is the desolved acetone and filler …..when we need to cut under water we use a hydrogen torch hey remember the Hindenburg ????????? oh well worksafe also if you have access to a simi /concrete floor and a fork lift ….set cyl in between the tires back forklift set brakes /get 36 in pipe wrench and a 5 ft pipe ….valve will come out / turn upside down fill with water and you can hand tite valve and cut away Good luck work safe have escape plan God bless Frank in Clover

Pure O2 and a match or spark and you'll see fire! Getting it on your clothes for instance and then adding a spark, but doing what you did is good. Also there should be a small regular head screw along the side of the post valve that is the relief valve and you should also unscrew that and take it off. Thanks for the instructable!

Once you get the valve out you can fill the tank with water which displaced any remaining pure oxygen, but, honestly oxygen isn't explosive (like propane) so if you leave it for a couple of hours with the valve off all you have its normal atmosphere in the tank. If you're using propane or acetylene tanks DEFINITELY fillip the tank with water to displace the explosive gases left behind as a precaution. Drain the water out before cutting the tank.

Those chimes are awesome. I have a tank already cut but was wondering if the clapper needed to be a specific size. I have a chain to hang mine with and had not thought about using rope to hang the clapper. I think it would be easier. Does the wind catcher need to be a specific size? Sorry for all the questions.

I just used the rope through and through. The wind catcher and clapper can vary as well. I used a large wind catcher due to the weight of the metal clapper. if you're using a hockey puck or razor scooter wheel you won't need as much wind to push it around. If it's too small or large you can always make a new one.

You can find a steel recycle phon number in the yellow pages. If not your town maybe one close to you. Or you could goole it.

I discovered a GREAT source of old tanks. If you live in a big city there will probably be one or more recycling yards where they take in steel, iron, aluminum and stainless among other things. In one particulary large yard where I live (Dallas), they take old compressed cylinders and cut them in half with an oxyfuel torch when they reach the end of their usefulness and recycle them along with the other scrap steel. If you bring the yard enough scrap to recycle (they weigh you when you go in and when you leave), after you unload, pick up a few tanks, it's possible to get your tanks for free!

 Instead of using a metal clapper, you could use a hockey puck.  It's hard enough to give a good ring, but soft enough to make it more of a gong sound than a clang sound.

I'm planning on making a "temple bell" from an old CO2 bottle from a keg-a-rator. (It's ok, I have another tank).  I'll use a hockey puck as the clapper and a knot at the end as a handle.

Great instructable!  I'm sure I'll use it as my main source when I build mine.

I was just looking at a CO2 tank for a soda system.. I think that would be wonderful! The Hockey Puck clapper idea is top notch, but, watch for the throw of the clapper rope.  If you are hand ringing this should not be a problem, however you do not want a lot of throw in a wind powered apparatus. Cheers and PLEASE post some pics when you are done or at least make your own instructable!
