I am looking for instructions on how to convert a Paintball Marker from CO2 to compressed air. Please help.THX

most all paintball markers can run on either co2 or compressed air.  no conversion is required. unless your paintball marker does not have asa connection (screw in for bottles).  then a paintball professional is required

your best way to go since the paint is already dry is to use Acetone. Make sure to remove the barell from the marker and use in a very well ventilated area. also as with Gasoline, paint thinner, mineral spirits and also acetone they are ALL EXTREMELY FLAMABLE, and you should use caution when working with any of them. Make sure you clean the barell afterwords to remove any residual chemical on it. ANY paint removing chemical will damage the inside of your marker, O rings will disolve as will you seels.\n\nAlso if you really want the barrel to look great you can send the whole thing, marker and barrel to get anodized in whatever color you want. usually costs around 80-100 dollars.

Don't listen to the above post. CO2 is not flammable, and you are not necessarily asking for it to be pressurized. The cheapest way to get bottled CO2 is to catch the products of a combustion. I would try to suck the smoke of burning coal into a bottle. Another way is to make your own carbonic acid by blowing air from your lungs into watter. Of course using these cheap methods you'll never get a good sample (eg, humans breathe out about 20% CO2). Perhaps there is a way to get rid of all the gasses?\n\nActually, there are "air sponges" that absorb certain gasses. If you could pump air though enough of these filters to take out all the gasses you don't want, you could be left with pure CO2.

I don't know that you can, different solvents react differently to pressure, so I don't think it's a one eqaution fits all kind of process.  That's why they all have different graphs for phase vs temperature/pressure.  I'm sorry.\nSounds like you have a pretty high boiling point though, the things I've taken off that had to be real high temp were water, toluene, and pyridine.  Could it be one of them?  They smell pretty different, so you'd know which.  \nThat's an interesting question though, I've never stripped a solvent that I didn't know what it was.

u will find lot of papers regarding air compressor in this site\nhttp://air-compressor-guides.com/

you could get a low end spyder for under $75 which are about the best youre gonna do for a marker that cheap. if you dont mind buying used id go to ebay, you could probably get a decent used marker there for $75. dont buy walmart crap. check out www.paintballgear.com if you wanna buy new, its one of the cheapest places to buy paintball stuff, and check out www.pbreview.com for reviews on paintball guns before you buy them if you decided to buy a less popluar brand of marker to see if youre getting something decent or a piece of junk.

You might work up some Q&A while showing this old demo of the effect of atm pressure...thereby adding some visual interest to the subject.\n\nAdd a few oz of water to a square-sided, metal, one-gallon can having a tightly fitted cap...bring to a vigorous boil (cap now off, please :-))..) and continue boiling until all air is expelled...screw cap in place and allow to cool...they will see the can collapse.\n\nWork up questions about the vacuum thus created (by the condensation of the water vapor) allowing atm pressure to exert its force.

look at www.lonestarcompressor.com I typed in Yahoo search "screw compressors" and come up with over 800,000 hits!

you need practice. i hope when you played on your buddys field his field had a good air bunker set up. playing air ball is a different sport then playing any other type of paintball, especially if your just messing around with your buddies. i played woods ball for about 2 years, than spent about 600 on new equipment once i started playing airball. you must have good equipment, it wont be worth it to go out and get dominated. i hope you have a high end electronic marker with high pressure air. your also going to need electronic hoppers, and most of all, you need to have a harness. you must have atleast enough paintballs for about 3 hoppers full. no use for a front man or back man. you from man will get shot and your backman will get cornered. naturally you guys will be in different positions in the fron or back of the field. if you want to win, take it seriously. I have been playing for about 6 years, and play against Dynasty weekly. Dont be surprised when the guys you play have the best equipment. Lots of people you play will have the top of the line equipment, and it IS a big advantage, next to experience.

A barrel kit with different barrels would be the best due to the fact that paintballs are different sizes and to get a better accuracy you need the barrel that you can blow a paintball through easily..\n\nThe Silencer\nwww.texasghostwalkers.com

I think the only pratical way ot do this will be to distill the kerosene.\n\nBut be aware that you are probably breaking the law by doing so. The colouration is added to make it comply with safety laws.

Depends my friend bought a refurbished gun at a paintball store and it broke in the first game. so, if possible i would ask the owner of the gun if you could test it out.

Take 2 hard glass boiling tubes.In one of the tubes put small pieces of wood, and some water in the other tube.Heat the first tube with burner.First heat gently and then strong heating.Through a delivery tube collect all the gases produced in the first tube under water in the second tube.By means of another delivery tube the gases over water in the second tube is taken out. This gas is simply called wood gas.Though we call it wood gas it is not a simple gas but a mixture of many.You will see  drops of black liquid at the bottom of the second tube .This black liquid is called tar.Usually methanol and acetic acid is produced which mix with water in the second tube.Residue left in the first tube is charcoal.\n\n\nBoiling point of methanol is abt 65 degree celcius and boiling point of acetic acid is 118 degree celcius. Acetic acid is a high boiling liquid then methanol. On the other hand, water has a boiling point of 100 degree celcius.Now apply fractional distillation to separate the three.

I think you talk about a Paintball Marker Tank. They are High Pressure Air Tanks, can shoot paintballs. 3000 psi is near 210 Bar (Atmosphere). It means Its not a toy :D

Yes such devices exist. I used to have a paintball coach that would fill his tank with his scuba tank.  You can use nitrogen or High Compressed air. Look at my source. Good luck- I know paintball can be expensive (I used to play on a competitive team!).

First step\nKnow the properties of gases\nCarbon dioxide will turn into a solid while cooling air, so it should be removed. \nAll remaining gases will become liquid when they are cooled. \n\nStep 2\nThe only step to separate gases in the air is to cool them. There are  2 principal ways: By reducing the pressure from standard pressure to lower presure values. OR by decreasing temperature. \n\nMETHOD: Fractional distillation of air should be used. It involves pumping air into a container, after having removed carbon dioxide from it. \n\nCarbon dioxide, being an acidic gas, is removed by passing air through an alkali by bubbling the air through the alkali. \n\nThe air rid of carbon dioxide is then passed through a special and sealed container, where the pressure will be reduced for the gas components to appear as a liquid. On the basis of recorded boiling points of gases, each gas is collected in turn. \n\nCONCLUSION:Thus you have separated the gas mixtures from air. You can use them to propel rockets.

I normally get my paintball stuff from actionvillage\n\ncheck out the two links, I think that's what you are looking for.\n\nhttp://www.actionvillage.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/DisplayProductInformation-Start;sid=NGNLbDdGLS9KKHNRIX-LxD2SkSP-sDeY23E=?ProductID=7OXAqArbXzQAAAEIVKh97HMd\n\n\nhttp://www.actionvillage.com/is-bin/INTERSHOP.enfinity/eCS/Store/en/-/USD/DisplayProductInformation-Start;sid=NGNLbDdGLS9KKHNRIX-LxD2SkSP-sDeY23E=?ProductID=CnLAqArbfngAAAEIm6h97HMd
