SpudFiles

Hello, everyone this is my first post on the Spudfile forums, I am new and need a lot of help too My first question is how do you modify a refrigerator compressor, I understand theres a in and a out line along with all the wiring knowledge. But what I don't get is how should I attach my connectors/air fittings, what hose should I use (i'm only going to 350 psi MAX because I'm new) I saw this video [youtube][/youtube]
In this video He welded a manifold, I like it but my problem is I can't weld. I need to find a way that doesn't involve welding but is still safe the max psi I would ever go to at this time is 350 psi no higher, so I need something that will be safe around that much pressure. If I left any important info out let me know thanks for reading.

UPDATE: I did some more looking and came up with this http://www.spudfiles.com/forums/my-comp ... rt,30.html pretty useful but still need lots of HELP!!!

as far as i know there are three pipes coming out from the unit one is sealed as that where a repair guy would re gas the system this i don't think you need.
then there is one output to loop and one input from loop i think its those two you need to get a large amount of pressure then you should compress the air intake. any questions just pm jackssmirkingrevenge he most probable help.

If you can't weld, compression fittings are your friend!

Measure the diameter of the compressor pipes.

Say it is 1/4" OD, you could buy these: http://www.ebay.com/itm/Lot-of-25-New-B ... 3a7dd944eb

This would then let you connect one of these: http://www.ebay.com/itm/New-Paintball-C ... 4854a85674

You could then fit 1/8" male quick connects to whatever launcher you want to fill. I believe one is included already in the above set.

Thanks for the info one question though what would I use to secure the first connector so it doesn't fly off? or would it just be a tight fit?

Thanks for the pictures this helps a LOT 8)

i've used compression fittings on 350 bar hydraulics, so this should be strong enough to hold 350 psi

What should I do for a regulator I noticed that the ones at hardware stores don't go past 200 psi, were can I find a better regulator?

It would help if you would describe your firing setup, are you going to have a main tank at 350 psi and firing chamber at 100 psi, what are you trying to achieve exactly?

The cannon I am building is not a hand held cannon it is stationary its going to stay in one place all the time, the fridge compressor will always be connected the cannon because there is no tank it just builds pressure, the cannon runs off a solenoid valve not a hammer valve, only a remote control to fire, the whole cannon will be anchored to a wooden board the barrel of the cannon is a coper pipe, this cannon will be for firing BBs not spuds (this cannons just to destroy stuff lol) If you need any more info feel free to ask, thanks for the help.

Also one question were do I get a good solenoid that can support high pressure of about 350 psi? thanks

Compression fittings can be used to very high pressures, some into the thousands of PSI. The actual rating for the one you use should be available froom the manufacturer's web site.

Compression fittings are a bit tricky to use. They need to be torqued just right. Too little torque and they leak, too much torque and they leak. In general they cannot be reused since the ferrule can't be removed. (You can usually disconnect and reconnect a particular fitting, you just can't remove the fitting and use it on another pipe.) They also require a well shaped pipe so don't crush or distort the pipe if you cut it.

Jack- If the pipe is painted should the paint be removed? I've never tried a compression fitting on a painted pipe.

Do you guys think this is a good solenoid valve for my uses??? http://www.kleen-ritecorp.com/p-4434-de ... losed.aspx Thanks for all the help!
