Just so you know the the plug you said you got from a computer is called a "I.C.E" power connector 😊. You can buy a male and female which is fantastic if you want to make a longer power Leeds. I am terrible at anything that involves any sort of DIY Projects I've got two beer fridge compressors and I freezer compressor and I would like a compressor to just clean out my computer so I'm going to watch your videos over and over to see if I can I can do it myself with her any of the sort of tools you have😊😊😊😊

[@saeedabulhusn4625]

Nice project, but the opening at the bottom is meant to be a drain, and should be fitted with a plug or a drain valve. The relief valve can be fitted to the outlet using an additional 3-way Tee before the 4-way Tee. You will have condensation at the bottom of the tank when you use it, and that should be drained regularly to avoid corrosion in the tank. Also, you want to avoid letting that water go into the relief valve because it may cause it to fail (therefore fitting the relief valve to the bottom is risky).

[@EricStrebel]

@James DeGray It doesn't make any sense to be doing what you are saying. A auto drain valve is completely different from this. Like Saeed says, it should not be mounted there and should be preferably installed perpendicular so no water collects in it----anyone that lives in a climate that freezes---you sure do not want water to freeze in a safety relief!

[@EricStrebel]

Watch my compressor upgrade video.

[@1AXMRDR]

Nice build, good video. Enjoyed the stop motion segment. OK, now I'm playing the armchair quarterback. Hearing how quiet it ran was crucial, telling how long it took to fill the tank would have been nice. These types of compressors are cooled by the cool returning freon from the evaporator of the frig. Adding a fan to blow on the compressor would seem to be a good idea. The run times of this compressor are going to be long. Using common hand tools would have been more useful for others to mimic your idea. One other thing that you need to address is that the oil will travel along with the air. You need to design and install an oil trap to allow the oil to return to the compressor once it shuts down. Trust me, I slept at a Holiday Inn Express last night.

[@EricStrebel]

See my latest video here kzbin.info/www/bejne/gKLUfaqro6tkkKc and you can hear how quiet it is and learn about the oil, not an issue BTW, but the water is.

[@AtlasReburdened]

If you can make industrial rated solder joints and follow best engineering practices for high pressure air, you can use those compressors to build 600-2000PSI no problem. Don't though, high pressure is the shadow of death until you really know what you're doing.

I think I may look into building one of these to replace my homemade air brush compressor. I made one of the $200 ones I see online out of a $60 harbor freight compressor and a throw away 1.5gal tire tank. Works but its been through a house fire so it looks like one of these would do way better

[@EricStrebel]

shawng7902 thanks for the comment and support!

[@nlo114]

As your compressor is rubber-mounted for anti-vibration, it would be worth putting a few coil-turns in the tank-line from the comp, to prevent cracking at the joints. Also, less vibration noise gets through the pipe.

[@tonsssedell4318]

You could even use a pressure hose. A bit easier to fit at least without the pipe tools and skills, and even more vibration resistant than a coiled pipe. I have to admit it probably wouldn't look as professional as a a copper tube.

[@VG-rj8pn]

nlo114 use hydraulic hose instead.

[@ImAdapt73]

"Swage" is what you did with the copper tube. Flaring tool forms a taper, or bell to the end of the tube. Nice job on your compressor and video! Looking forward to finding out how long it lasts, I hope that engine oil works out. :)

shafferjoe1962: Like Thomas barlow says wait for your refrigerator to come on and listen. Sounds like pssst on, pssst off. That's it. these compressors were made commercially and sold for $375.00 in 1980. I had one for airbrush art work. I lived in a condo and could run it in my Den and not annoy my next door neighbors. Nice job Eric!

[@CorbinAce]

Eric: I still have that old compressor. I haven't used it for many years. I have a garage now so I don't need the silent compressor. I have to take it apart though. Something inside is rattling when I turned it on. It is no longer silent. :O) It has a large clamp similar to a hose clamp around the center of the tank where the weld was, so, opening it will be easy. I am curious and have to attack that project. There is a lot of dis-assembly videos if I have a problem. Maybe I can fix it.

[@robertdeleon2267]

I saw the whole video and you would think after 10 minutes you would at least have the sound of the air compressor. I wanted to hear how quiet it was.

[@EricStrebel]

so quiet it's not worth focusing on, really it's that quiet! Most of the time I don't even hear it turn on, I just hear the relay click on and off to start the compressor. You are not missing anything with out the the sound.

[@undede]

exactly!

[@danielmiller2886]

Around the 9:35 mark you can actually hear the compressor running. Sounds just like a quite fridge. It’s just so quiet that it doesn’t overpower the music and talking, but it’s there.

[@VidarrKerr]

Yeah, I completely agree with you. Maybe it is ultra-quiet, but I still want to hear what that ultra=quiet compressor sounds like in the real world. It would be better than that music, that is for sure.

Or you could just go listen to your own fridge

[@Elfnetdesigns]

We used to use old compressors in the 80 to air up bicycle tires when I was a kid.. We didn't have a tank we just went straight off the output of the compressor to a tire pump hose that was held on by a hose clamp.

[@seniorcitizen5431]

Hi Eric, Great instructional video. Thanks in large part to your video, I’ve made 15+ compressors for others (from different brand tanks and from dehumidifier, refrigerator, room AC compressors) and all worked fine. I’ve recently come across a problem I can’t seem to resolve. Using AC compressor, Porter Cable 6 gal compressor, new 4way pressure switch with unloader valve, After filling the tank, with no leaks, etc. when the unit shuts down oil vapor (smoke) comes out of the unloader switch…..just for a minute or so. Then it stops. I’ve tried this with the compressor cold (so no thermal issue) and from either, Empty to full pressure OR from cut in to full pressure. Still get the vapor (which does smell a bit). So I put a different compressor (from a dehumidifier) on it and still same problem. These were from a working AC and dehumidifier. This is nothing different than I’ve done in the past, except now I get the oil vapor. (YET….”something must be” different to cause this. Any suggestions as to Why this is happening and How to remedy it, would be really appreciated. I’m stumped !! (as an aside…..on the others I’ve built, on purpose, I ran them from empty to full repeatedly till the thermal switch would stop it……and no vapor !!!!)

[@EricStrebel]

Do you have a one way check valve in the system? You need that so the compressor can start with out being under pressure and it should prevent vapor going to to the compressor

[@seniorcitizen5431]

@@EricStrebel Thanks Eric; yes I have a one way check valve and I believe it’s functioning OK. The tank holds pressure long after it’s shut off. I’m just baffled on this. I’ve built so many in the past and they’ve all worked fine. Again thanks for your reply.

[@JohnNordDesigns]

Here is a update on my comments below Eric. I finally figured out why these compressors do not always start after being switched on immediately after running. Normally you have to wait 1 to 3 minutes for them to restart. This is because they are induction motors. Because of them low torque of them, they need the wait time, for the mags to align properly to start rotation again. I have cured this in my latest jewelry compressor I built. 3 things you can do. First use a Condor Mr11GC2E pressure switch. This pressure switch has two screws. With these you can set your cut on press. at 60 and your cut in press. at 125. This will give ample wait time usually between run times if your using GRS equipment that runs at about 25 psi. If you need more time, between start and stops, use a 10 gallon tank instead of these 6 gallon ones. These compressors can pump them up to 120 easily. This will also give you more off time between runs. Lastly if you really want to cure the problem of not starting without waiting 1 to 3 minutes......on your compressor, be sure you have a PTC relay, a overload switch, and a 12 - 15 uf run capacitor. Usually your compressor will have these on them. Then, to the run capacitor, hook a Supco SPP-5 hard start kit. This simply hooks piggyback to the run capacitor wires. It increases starting torque by 300%. ( make sure your compressor is at least a 1/3 hp). I used this on mine, and it will immediately start everytime, with no wait time. This sounds like the easiest fix for these induction compressors.....but , I don't not know, over the long time, if it will shorten my compressor windings. I suppose I will know in a yr or two. Lastly, for those of you, that say these compressor overheat......Always hook a air filter to the suction port, AND the process or service port.....this will let the compressor suck air in both ports and cool it better. Also, only use it in rooms with less than 90 degree air temp. This is all that is required to keep them cooled from what I am told by designers. Good Luck. I hope to post my own You tube video build, once I have better internet.

[@EricStrebel]

Great, information! Thanks for posting and sharing with everyone. Look forward to what you post John Nord

[@IamRedeu]

There is no unloader in the system. The compressed air can prevent another compression stroke. Get a pressure switch with an unloader, and install it in the system to prevent the compression lockdown. The unloader allows the cylinder compression to bleed off, which allows another compression stroke.

[@WojciechP915]

Makes me want proper sheet metal equipment.

[@philippe5394]

Hello Eric, it's a beautiful creation that must be usefull to you, it's beautifully done. One thing bothers me, and it's not the tin solder. The bottom of the tank must be equipped with a drain to let the condensation out and it's a kind of muddy water. However, you installed the safety valve, at a low point. It may therefore not work if it is reached by this water when moving the compressor for example. I advise you to replace it with a small drain valve and install it on the top of the tank.

[@saddle1940]

I would have added cable ties between the mains IDC socket and the plate above to hold it as well as the epoxy. drill a couple of holes in the plate above and thread them through making a loop. For a bit more safety, you can also get an IDC socket with a fuse built in. Just a couple of questions: Where does the water collect (in the tank probably) and how do you evacuate it? Did it take long to fill the tank? The fridge compressor isn't a fast mechanism.

Just how quiet do you need an under performing compressor to be? You can afford all of that metal shop equipment, but you use an unmounted hack saw blade to cut copper tubing? You can get a 2HP 4 gallon oil lubricated compressor from Harbor Freight Tools for $150 regular price. I have had one for at least 12 years and it still works great and is very quiet especially compared to oil free compressors. While most of the work looks well done, it seems like a lot of work for little reward, especially scrounging all of the parts!

[@phelixanger6152]

Normal refrigeration oil can be hygroscopic, that's the only issue with using it for the "air compressor" in this case. Either way that isn't a problem, I would just use regulator air compressor mineral oil, not motor oil since it is rough and not meant for these sensitive refrigeration compressors. It is also cheap and easy to buy. Change it often and you will be fine since refrigeration compressors are designed to work with thin mineral oil/poe/pag/akb etc. but thick motor oil might be a problem over time. It might be fine, but it's cheap to get mineral oil and it will work for years with no problem. Either way, this will make a nice quiet slow air compressor easily.

[@EricStrebel]

Thanks for the information, much appreciated

[@phelixanger6152]

@@EricStrebel No problemo! I have been using a rotary compressor as a vacuum pump for years with the mineral oil it came with and it still works fine. Moisture in the oil is a bad thing when it's in a refrigeration system but the compressor doesn't mind it much. Not only that but since they get quite hot I am sure most excess moisture evaporates when being used as an air compressor or vacuum pump.

[@eldonashbaugh493]

Refrigeration compressors are made to move oil around the system to lubricate the other parts. You will get oil in your compressed air and the compressor will run out of oil and that is it.

[@EricStrebel]

Eldon Ashbaugh actually I don't find that to be the case. The compressor is meant to move freon and it moves a bit of oil when it does that. I have not seen any oil or water in my tank thus far after over a year of shop use. I don't see any in my trap either. Quite the reliable unit actually thus far.

[@robber576]

Putting the relief valve at the bottom is not "risky" but outright dangerous, you have bought a tank which used to be part of a compressor similar to what you have build, that means it is probably rated @ 11-12 bar(160-175 psi) which the old refrigerator compressor can pump easily, if the pressure switch fails you have a bom in your garage. The relief valve will fail after a year or so because of rust build up in the valve, the vessel is made of steel that will rust due to condensation in the vessel. The bottom connection is meant for draining, you will need to add another tee to th top connection to provide for the safety valve. Otherwise, nicejob :-)

[@JackPott554]

Eric Strebel also, I bought the quietest compressor I could find off the shelf and it's still 79 dB SPL. It's much louder than an idling car to give perspective. This looks like it shouldn't be any louder than a fridge? Given the slow full rate, if I built this I would have to go for a giant tank as I mostly use my compressor for cleaning and sanding. Would think yours is perfect for brad nailing etc? Cool build

[@tommurphy4307]

and that compressor would be a cheap imported compressor that would not last nearly as long as this one. add to that the fact that you would have ready sources for any parts that may wear out or fail with this one, and then add to that there is no way you would get the quality of detail in the assembly for the price point you are referring to, and you have no valid argument, sir.

[@JohnNordDesigns]

I built two of these following your video. There is a problem I have not solved. A compressor like this won't restart immediately. It takes mine ( using a unloader valve to relieve pressure on discharge before start up) about 2 minutes minimum, before it will start right up when the pressure switch calls for it. If the time is shorter than this before the pressure drops to the cut on pressure, during usage, the motor will just hum, creating heat in the start windings, and sometimes popping the overload. This can't be good. I have tried all kinds of ideas to cure this. None have worked. I believe the reason they wont restart immediately, is because there is air trapped above the piston that the unloader cannot relieve. Eventually this air leaks past the internal valves and the load is gone, allowing compressor to restart. What these need, is a pressure switch that can be adjusted on the on pressure and a separate adjustment for the off pressure. I have not found one, but if I could, I could set the cut in at 40 and the cut out at 120. Then during usage, the time it took my engraving equipment to use the 80 lbs of pressure, the 2 minutes would of elapsed. Or , I am considering a large tank, to hold more air. Then the time might increase also. If you build one, consider this. I burned up my first one, because I did not realize it was humming and not running. They are quiet! But when that overload pops and sparks, you know something went wrong. Now I am using a brand new refig compressor, new start capacitor, overload ect.....still takes 2 minutes to restart. If this could be cured, these would be a good idea. I would welcome any suggestions.....................

John Nord excellent that you built two based on this config. I have not encountered this issue as mine is for very light duty use in my shop and it never runs much. But, what you suggest makes sense as these compressors run on a high pressure setting. Perhaps a larger capacitor would do the trick to help the motor start?? just a guess. But I think a larger tank would also work so that the system runs less. Best of luck. Thanks for the comment and info. Wish there was a way for you to post pictures of what you built. I would love to see it. Cheers

Eric, I have tried a 3 n 1 start with capacitor and same result. I have tried 3 compressors, all new, and same result. But if I can keep the time difference between cut in and cut out of the pressure switch to more than 2 minutes ( preferably 3 minutes) then it starts everytime. To cure this, I am installing a Condor MDR 11 pressure switch with a adjustable differential kit Pn#230618 from Condor. With this kit installed on their press. switch, you can adjust the differential between cut in and cut out pressures to as much as 65 psi. This will give a much longer delay before it restarts using jewelers equipment. I am also considering adding a additional 5 gallon tank to it. These compressors seem to have no problem pumping up as long as they are running. But need sufficient time before restarting. So hope is, this larger tank & the adj. press. switch will allow this time. I do not agree with some people on the sight, that these compressors will overheat because they do not have the cold of freon returning back thru the suction line. I researched this, and most of these only need less than 90 deg air coming back into the suction port, to sufficiently cool them. Which, if used indoors, is not a problem. HOWEVER, I put a removable air filter on both the suction port and the service port to allow air intake from both points. This I believe helps cool it more. They can be easily removed to add oil when needed. I will let you know how this all comes out, and possible post pics when I am done. Thank you for your response.

@@JohnNordDesigns this all a waste of time if you dont have an oil separator with return to the compressor. The oil will eventually leave the compressor and it will seize

[@EricStrebel]

@I Not How See the latest update to this project here kzbin.info/www/bejne/gKLUfaqro6tkkKc I have no issue with loosing oil, water is a much bigger problem

[@qx3V45p]

Machine shop 101... NEVER wear gloves when using a disk sander! Seen some people loose tips of fingers when the glove get pulled into the gap between the disk.

[@EricStrebel]

Safety is important. I agree, Wear a pair of gloves so you don't burn your hands, two schools of thought here! I am wearing gloves on a pretty big piece of metal. Never do I get close to the wheel. So not an issue for me. If it was significantly smaller I would wear a pair of tighter fitting gloves. Don't get your fingers close to the gap at the bottom of the disk an the shelf. I would recommend a pair of mechanics gloves. I am aware of the danger, know your limits and be smart. Thanks for the comment and support.

[@TheUPX]

please tell me why you select 10W40 oil and not 5W30 or 0W20 or simple regular air compressor? thanks in advance.

[@EricStrebel]

It is a bit more heavy duty, but with the thinner viscosity

[@doncodman913]

Hi Eric . just viewed this . looks good ,if you wanted a quicker fill possibly 2 compressors on top ?? What sort of Amps is that compressor using 3 or 4 Amps ?? hope to hear from you ,Don

[@EricStrebel]

I looked to see if there is a rating in the motor for the amps, nothing is listed on the label, sorry

[@emilflognoid1532]

This was a really good video, the only thing you didn't explain is how you threaded the barbasol bottle to the compressor to make the muffler?

[@nx7640]

Hi, what do you use as background music.. very nice

[@sergiobarbalic8148]

hey Eric Nice job Man !!!! I have one question. Can I use this compresor for a gun spray pistol to spray on wood ? Thanks in advance for your time

[@EricStrebel]

you will need a bigger thanks fo that, I have a video about upgrading this compressor with a larger tank, BTW

[@sammyg3697]

You should open the relief valve after every use because of condensation

[@Ricopolico]

Puzzling. This guy has a Beverly shear, a metal-cutting vertical bandsaw, a press brake, etc., but no hack saw frame or, better yet, tubing cutter? By the way, how much oil does a refrigerator compressor take?

[@andregrafia1914]

excelenteeeeee!!!!!!!

[@SherwoodBotsford]

Nice video. Good editing. How many cfm do you figure you get from it? What tools can you use more or less continuously without having to wait. FWIW: Friend did this but used a 30 gallon water tank as the reservoir. Would take 45 minutes to fill, but that gave him 10 minutes of 40-60 two-inch crown staples per minute for 10 mintues. (Building bee hives.) Since it took about 45 mintues to set up all the jigs for the next 50 frames it was a good match. In general I suspect that a larger tank would be useful if you hve room for it.

[@jackthomas1978]

Good see he soddered the copper and listed the bolt sizes.

[@markh2005]

Great t shirt!

[@richardnanis]

Hi there, what is the max. pressure you can reach with an old fridge compressor? Can it achieve 120 psi (8 bar) or more? I was afraid of overheating the compressors with that much pressure and went below 80 psi. 20 years ago i built an home made compressor out of 3 fridge compressors in parallel to fill up a big gas tank. Still working today but one compressor quits - makes a summing sound but doesnt pump.

[@EricStrebel]

richardnanis don't know the max pressure, but I charge my tank to 100psi, so it seems feasible.

[@thomasgilbert4131]

My dad converted an air compressor from a commercial air conditioning unit to use in his garage 35 years ago. Some of the parts he used were galvanized metal and not brass or copper. All the galvanized parts rusted and blocked the airflow over the years and had to be replaced with brass. So use what you have but if you need to buy some parts and have a few extra dollars buy brass and it will be maintenance free.

[@justinking664]

Whats this guy got a regular metal fabrication shop in his garage .you think he will let me borrow that equipment . 😄

[@cyberlanboy09]

Is it still operating? I'm making one myself, was the 10-40 oil a good swap? Any oil changes so far? I read all about the problems with moisture and etc etc etc.....you read up yourself. And lastly was your compressor running pretty warm mine is staying steady at 150 f and I'm not sure if thats normal or too high.

[@EricStrebel]

Yes, still running, there is a follow up video with a new tank and some adjusts, oil is the same oil, unit never really runs long enough to get more than warm, works flawlessly and very silent!

[@danpmatz]

I do heating and cooling what if I put a 5-ton compressor from an AC unit

[@JessicaTG2008]

Just wondering. This style of compressor is designed to be cooled by the Freon inside the unit while lubricated by the pool of oil in the bottom. Once you remove the Freon, how long will this run before overheating? Compressing air creates heat, friction creates heat and the oil isn't cooled, nor is there any kind of heat exchanging to air and it's sealed in a thick metal container so I am assuming you can't use this for anything that runs this a significant amount of time.

[@EricStrebel]

It runs less than 5 minutes at a time in my shopJessicaTG2008 when it runs. It probably runs about twice a week to fill the tank. It does not even get warn when it runs. Thanks of the comment and support.

[@chrisgriffith1573]

Two thing of note in this video: , use a refrigerator compressor, and change out the oil. Oh, it helps if you have a metal working shop.
