- I take you out to the garage to take a look at my home made air compressor. This is a hand me down from my grandfather, Orville Hebel, who actually made this and used it in his home workshop. I've owned it for over 20 years, but I remember using it when I was a youngster.
Lovely video... A great way to start my day, look at the world outside and say to myself, "there is hope for humanity yet". Thanks for posting this up! This video has it all... Ingenuity, Common Sense, Thriftiness, Sense of Family and Good Will. The sound of the compressor sums it all :-)
+JohnnyJim J Thank you very much for those kind words. I always enjoyed visiting with my grandfather. He always had something nice to share with me. Thanks for watching my video.
Really cool I’m in the midst of a similar project for a mobile paint compressor it brought me to your video
I'm planning a compressor build like this, mine is using a 30 gallon water heater as the pressure vessel and a 5hp home A/C compressor to pressurize it. The whole thing is pretty compact and quiet (just barely quieter than yours if my ears are correct) and pressurizes pretty quickly.
I fabricated a bracket, and have a York 210 compressor bolted to my engine in my pickup. Great for onboard air, and it's a really fun project!
Thanks for watching. Now you can add an air horn for all those texting drivers!
Ron Briz lol yup! With a $7 solenoid, I've got a big Mack horn indeed the hood haha.. have a great day!
As they were designed for AC systems, York compressors normally spits lots of oil through the discharge port. Now for this kind of application and after watching this setup, it seems they work better at lower revs. Great video !
Thanks for watching. Yes, it seems a small amount of oil makes it into the tank. I've notice when I drain the water out of the bottom of the storage tank, it's slightly milky and light brown. It hasn't caused any problem over the years and the oil has probably kept the tank from rusting out.
Thanks! It's been running like that for 40 years. I did have to replace the motor in 1993 because while running and up to almost 90 lbs of pressure, we lost power to the house. When the power came back on, the back pressure was to strong and the motor couldn't start and just sat there and burnt up. The back flow restrict valve solves that problem.
Can i se all of methods to make that air compressor, i plan to build like this.
This gives me a neat idea. I do air cooled VW's and Chevy trucks. I had bought an old but brand new JC penny air conditioning kit for a a vw bug (way back when they sold car parts lol). and I have the York compressor that it came with, that was never used. I could mount that compressor on the Chevy, to fill an air ride tank I also have lying around. I'm building a tandem axle setup on my 79 k30 dually, and running a 4 link suspension for both rear axles, and using medium duty air bags that are for something like a greyhound bus. they only take a max of 120psi, so this should work. a lot better then those darn electric air ride pumps that dont last very long.
nice set up. I love the sound of the compressor
Just came across this researching sand/soda blasting and recognized the name! That is a cool compressor and tank! Thanks for sharing!
Actually I wanted to respond here. I left you a comment on one of your router videos that I thought was on this feed. Anyway, Mac, thanks for watching. I enjoy your Keeks.
I came across this video researching sand/soda blasting too I can't decide which would be the best to do on cast aluminium which do u think :)
That's pretty cool. You should definitely hold on to it!
My Grandpa has long passed years ago, but some of the tools that Grandma gave me, brings back the memories of him daily as I use some of his tools. Thanks for watching!
i like that kind of home air compressor
Your grandpa would be proud of you.
It sounds cool as hell
I have almost the same compressor. It was new some time in the late seventies and was never installed on a car. It has two cylinders. Yesterday it stopped delivering air.and the sound changed. I took off the head and valve plate to inspect the valves and the nut and bolt that hold one valve assembly had come loose. There was some minor discoloration from corrosion on the valve discs so I turned them over to use the clean side. I reassembled everything and am back in business.
I have no tank, so I let air bleed to keep from stalling the 1/2 hp electric motor.
I was surprised to see the same compressor as mine. My set-up is vertical with the compressor over the motor and the whole assembly wheels around like a hand truck.
Paul Ohlstein Very interesting. I've not taken this compressor apart. It has provided me with great service. Glad to hear you were able to troubleshoot and overcome the malfunction. Thanks for watching.
+Paul Ohlstein Great you could get it back to work by simply reversing the valves! I love these old machines, fixing them keeps me sane and reminds me of the times machines were built by and for people. I rebuilt the one way valve on the old Sears compressor I just got by replacing the original rivet that was holding the rubber flat washer against the seat with a faucet washer screw. Yep, it had a snap ring making holding all the components inside, that made it possible to take it apart and replace any single internal component that could have failed. Try to do that with modern components!
Very nice, thanks for sharing!
I have a a couple of York 210's sitting around. one of them I got off of Ebay and the other one I found at a junk yard for $45.00. Great Compressors! :D Just keep the oil topped off and it will last a life time
Oil, crap it's been over a year since I've checked it. Thanks for the reminder and watching my video. Enjoy!
athiker7209 It is a good thing it is not running at the rpm a gas engine would put out. lol
I know there is a compressor oil, but I've always used just straight 30 W oil. Like you said it's only running 1/3 the rpm it would normally run if it was on a gas engine. Do you recommend that I drain the oil and put in a high compression oil?
repeatman I think I may be ok. Some chat rooms say they use 30 weight non detergent. Mine is a York, but not sure on the model. It looks very similar to the model you mention. My grandfather did put a 90 deg elbow fitting near the bottom to add oil. It's topped off and purring like a kitty. But I'll check the oil more often.
Nice work.
Abraham Delatorre Thanks for watching! Regards, Briz
I need to put me one of those together for my little shop. Thanks for sharing this video and the info. Now i'm off to dig in my nephews junk car parts pile for a compressor.Thanks again.
::SUBBED::
Hey, thanks for watching and the sub! Regards, Briz
Nice project
Hey Vince, saw this over the weekend but I waited until this morning to time it. The tank holds 30 gallons. I drained the air until the compressor kicked on at 65 lbs. It ran for 6 minutes, until the pressure reached 95 lbs. If you want to know what it takes to fill it from zero lbs, let me know. That will take much longer to do.
You seriously need to put a modest AFTERCOOLER in the discharge side of the compressor.
I would be willing to bet that the air hose in the pressure side runs quite HOT.
That's interesting, I hadn't noticed it. The next time it runs, I'll check that out. Thanks for watching.
well done very small output compressor
the only issue is the heat transfert that occurs when compressing air instead of freon
if the stop time stays long in comparison to run time, it is OK but in the reverse situation, overheat will take place as there is no fins to dissipate the compression heat
You make a good point. Thankfully, this compressor doesn't get much of a workout. When it runs, it's about 6 minutes, it just sits there for a couple of weeks. With that 30 gallon tank, bicycle tires don't take much volume. Thanks for watching, Briz
A nice quiet under-stressed unit. Should last forever at that RPM.
TheSpazModic It's been 25 years since my grandmother gave this to me. I haven't watched this video in awhile and can't recall if I mentioned that the motor my grandpa had burnt out due to a power outage and when the power came back on there was too much pressure against the piston for the motor to start. When I replaced the motor, I also installed a back flow restrictor at the tank so from the tank through the hose to the compressor there is no pressure. Now, when the motor kicks on, there is no back pressure in the line and the motor can get started. I'm real happy with the set up. Thanks for watching.
athiker7209 That was good thinking. I'll remember that if I ever build one. I have an old refrigeration compressor that I might convert one day.
Cool idea briz
Faril Bhagwandien Thanks, it's still working great. Thanks for watching.
well done thanks for shearing
Thanks for watching. Regards, Briz
Hey....Thanks for responding to my first question. Now for another....The compressor pump you are using......Does it have a oil sump in it? How is it lubricated?
thank you very much
Thank you for watching. Regards, Briz
It has an oil port at the bottom of the compressor, I've not taken it apart, but I'm guessing that there is a flapper stick on the bottom of the rod. As the piston goes up and down, the stick, on the down stroke, goes down into the oil and splashes oil all over the cylinder. Much like a 4 cycle gasoline push mower engine. Some of the newer engines now have oil pumps.
Watched the video without sound (I'm at work), so I apologize if you mentioned this: How many HP is the motor?
Robert Cipriani It's a 1/2 hp motor. Thanks for watching, Briz
Ron Briz I recon you should get 1Hp motor.
love it
Can you tell me how long it takes to air up?
Thanks for the video!
Can we run car compressor with RC 61 cc plane engine
It doesn't appear that you have an unloader on your setup. It would be a good idea. The 1 way check valve helps a lot, obviously, but n unloader will help it start up when you use it a lot. That compressor looks a lot like the ones my stepdad had on his Ford's.
I'm not educated in air compressors, and usually ended up learning the hard way. Thankfully, this unit doesn't get a lot of workout. It does a great job keeping my bike tires topped off. This compressor did come off of a vehicle, however, I'm not sure what model. I appreciate you watching. Regards, Briz
Would you please let me know that how much time it takes to fill the cylinder fully..??
Several minutes. Thanks for watching.
i think sir it will be better if u made the motor gear bigger size than the compressor one it will allowed you more cycle if it will be 1:2 ?
+Yousef Issat Yes, but the motor may then overheat. If you have an ammeter, you could try and as long as the amps the motor is pulling doesn't exceed what it is rated for you'd be good to go. Another thing to consider is what the pump was designed to rotate at. Regular compressor pumps prefer to run between 500 and 1000 RPM, not sure about AC pumps.
vortex222
Good point. the ratio would be a factor of that pulley versus the crankshaft pulley, and the motor's RPM range. As for durability... Don't AC compressors last years? What about hot climates? That would give an indication how long they can last.... With proper lubrication, that is... In other words they probably need oil to pass through the pump to work properly, and oil injected back in the inlet... I just got myself one of these old refrigeration pumps for a song and will be taking it apart during the winter lull to find out how it works... If I don't post back just respond to this comment, as I don't monitor this identity much.
I have a brand new york pump like that on a shelf. How much PSI can you build with that?
On this setup up I have it set to 95 pounds with the pressure switch, mounted on top of the tank. If that switch fails, my grandfather installed an emergency pop off valve (you can see the brass valve at 3:39) that resets automatically, mounted down at the output on the pump. I've plugged the hose to see how it works, and it seems to cut out around 120 lbs. But if I remember, I thought he said these pumps could pump several hundred pounds. I may have recently overfilled the oil, because I'm getting a lot of milky oil from my drain at the bottom of the tank. Maybe I should install a water/oil separator before the input of the tank. Thanks for watching!
Its called a ball valve. And 2 keep system dry. Use. 90proof. Rubbing. Achahol
Thanks for watching!
Way cool
Tyler Kezer Thanks for watching.
What is the horsepower and speed of the electric motor?
Hey Junk Yard, the motor is a 1/2 HP, running at 1725 RPM. Thanks for watching.
does rotation speed of compressor affect max attainable pressure or it just builds slower? Also what are the ratio of pulleys on this setup?
Hi, the slow rotation speed does not affect the max attainable pressure. Actually, with the slower rpm, that with have the smaller pulley on the motor shaft, will actually allow you to go to a higher pressure, due to more motor torque. But, it will take longer to reach the upper limit. A larger pulley on the motor shaft, and a smaller puller on the compressor, will reach the desired limit faster, but there will be more stress on the motor. So if you have a high HP motor, you can run the compressor at a higher speed. I'll have to get back with you on the ratio. They were just what they were when I received it from my grandfather's estate. Thanks for watching.
Ron Briz
Thanks for reply, I am building similar setup and will base the design on your compressor.
hooperwille I'm back from the shop and the ratio is 4:1. Four revolutions of the motor shaft to make 1 revolution on the compressor. Good luck on your build.
thanks
What is the motor capacity
1/2 hp, thanks for watching.
no safety valve on it???
Thanks for watching. Yep, there is a safety pop off valve mounted on a "T" connector about 2 inches from the outlet of the pump. You can take a view of it starting at 4:52 point in the video. It is spring loaded and will close automatically when the pressure is reduced. I've tested it and it kicks in around 120 pounds. Regards, Briz
How do you wire the compressor?
Sroor9001 The compressor doesn't have any wires. It's mechanically connected, by a belt to the motor. The motor is connected to 110 volts AC, with a pressure switch connected in series. If the switch becomes defective, there is a pop off valve near the output of the compressor, so you don't blow the tank. I would think the motor would stall out, or the belt would slip before the tank blew up. I test the pop off valve to ensure it functions properly.
Ron Briz great so woul you please tell me how is it connected I mean the motor
The hot wire of 110 vac goes through the normally closed contacts of the pressure switch. The hot wire leaving the pressure switch goes to the hot lead of the motor. The neutral wire from the wall plug goes to the other side of the the motor winding. Equipment ground goes to all metal case components. When the pressure is low, the contacts on the pressure switch are closed, causing the motor to run. When the desired air pressure is obtained in the tank, the pressure switch clicks open, causing the motor to stop. Thanks for watching.
Ron Briz but there is no inverter so it's running 110 vac from wall socket and it's 12 volt alternator?
The device that is connected to the compressor is a 110 VAC electric motor. There isn't any 12 volt alternator on this system. There are pulleys on the compressor shaft and motor shaft, linked together with a V-Belt. It's a pretty simple setup up the pressure switch monitors the pounds of compressed air in the tank. When the pressure drops to around 58 pounds (this is adjustable) the switch closes, sending voltage to the motor. When the desired upper limit pressure is obtained, the switch opens. I hope this has clarified a little better how this contraption operates. Thanks for your interest. Regards, Briz
Its called a check valve
MasterlyApple34 check! That's what it's called, thanks for the info and thanks for watching! Regards, Briz

I'm sorry for ypur father
Your
Knocking no oil in Crank case.
Got' r done!
Thanks for watching!
