Any excuse I get to use my grinders I do. Something therapeutic about them. Being a painter for a custom oem trailer shop love my job. But I would used a grinder then a orbital or Palm sander with 180 and 320 would only take a few minutes even by hand. You could still see the scrapes clearly. Still looks good, I would have used some spray can primer, then paint, some cheap spray clear as it's gonna get dirty and maybe oil leak out and such. Unless I was already doin a 2k clear on a show trailer or something. This gives me some ideas. But one I want to try is making a compressor from two push lawnmower engines. You take one and with a belt connect it to the other and take the spark plug out of your secondary and use a fitting. And your operational motor will spin the it and it pumps air a good bit actually good cfms. And can rig them up on one unit making it portable. Filtered air and their splash lubricated. As long as it has compression and you can get plug out. Doesn't matter if the carb is messed up or whatever don't need it. Just need air to get in. I've seen s couple videos on them. Or it can spin a car alternator hooked to a power inverter and car battery. You can also make little generators and pumps out of little two strokes as well. A small alternator or with a pulley change is easy even for a small weed eater motor to turn

This is what I was thinking I thought at first the drain might be the old top of tank last fitting he put in. You'd have to turn the tank forward 90 degrees if thaf was it. I didn't recall seeing a pressure relief valve. And was wondering if the compressor would run with no oil or how it would work as the oil will be pumped our the discharge in short time. But I wouldn't mind using some of these tanks as storage tanks for extra capacity if I got them free. 11 gallon tank is only like $40 and just needs a 1/2 inch npt fitting swap to get rid of the bs fitting they come with. Or Lowe's has a 7 gallon one 185 Pai rated with the regular industrial fitting and right npt on for $60. I run 2-3 compressors in parallel with a t fitting into a portable tank and run my main line from it. 50 ft lines to let the air cool for the separators and that makes it easy to connect to separate breakers. 40-50 gallons 125-150 psi depending on which ones I use. And 7 to 8 cfm@90 for if I use the smaller one with one of my other two 10cfm if I use my two main ones. And 12.5 cfm if I connect all three. Usually always have two. Even if I don't need both for some jobs I leave it connected for extra storage capacity. Works great for painting. And j don't need dedicated 220v and I can load it in and out my truck in 5 mins and paint or air things up anywhere. Get great deals off Craigslist for compressors oiled and oil less. All oiless use the same internals there's one company that makes the sleeves piston and rod. There's like two literally that cover every brand. And it only cost $30 if the motor is good you can get compressors for a steal and for 30$ have a brand new oilless compressors. Or you can go to harbor freight spend 300 on 2 21 gallon compressors or the 10 gallon versions and have 10cfm @90 the same as entry level 60s start out with for $500-600 without installation or wiring. And it's portable. Win win. Constant supply of cheap Craigslist compressors people never use and get rid off. Especially right before Christmas and right after winter ends people clean up. I wish I would have saved the tanks on a few. But once they get older and Don know previous drain history I've erred on the safett side. But a nice big propane cylinder would be great . If j ever do a stationary here it would be tank. Pricing tanks it's cheaper to buy station unit 60-80 gallons then just the tank makes no damn sense

I like your observations sir... It looks like you have a lot of knowledge about compressors 😊

You are right about this, I have an A\C compressor that i was going convert as shown in this video. With the compressor running standalone, it gets very hot! It also does eject fine droplets of oil as u have mentioned.

And the life of the compressor is also shortened because it sucks moisture and that is very bad for a refrigeration compressor , the oil is hygroscopic and absorbs moisture and deteriorates it too , anyway it's a good use before you throw it away .

It is true.

Saya dah bikin gan, pake tabung gas 3kg, gk pake sistem las cukup pake nepel dan shock...

trust myself more than anyone else alive, that's why learning and diy, or having the knowledge hands on, is super important. one time I didn't have time to do my own oil change , air filter etc , went to drive through quick change, watched like a hawk, stopped big mistakes, dipstick, air filter cover, oil cap not replaced correctly. This dude is my hero, I do my own mowers etc also my own electronics. my $1500 3d 4ktv isn't made anymore, $50 all in diy, back to 100% #supportrighttorepair

thanks men you just save a lot of lives. imagine people making DIY air compressor using old gas tank drilling it right away without filling watter to degas the tank ..

Its not gas tank bro this is some different 😉👍

@@MrDKDIY Hey, no worries 😉 Love the channel btw

@@jet4460 😎👍🏼

Good point about the recycling issue .In this world of consumer mass consumption and throw away goods , people have forgotten about how to rebuild things or tinkering . I grew up poor as a kid and learned a lot about mechanics and working on my own cars and whatever else I had to fix because we couldn't afford to pay for repairs or to buy something new. Funny how the same people who used to laugh at me because I was too poor to have new things would later come to me with all their mechanical problems . Now because of the lack of skilled labor and the lack of knowledge in mechanics or salvaging things we have a shortage of skilled labor in various markets like welding or electricians . All the kids are being pushed to learn about computers and IT when we really need skilled engineers and craftsmen (or women ) especially considering the fact that the infrastructure in this country is in dire need of a rebuild .

Michael Gale This man is a genius and he is gifted by almighty gun. It takes a genius to use the word “though” . So far I have compressor , given to me by a friend. Thank you Dk FYI , you rock , I need a tank , though. 😂

Thank you 🙏🏼

Thanks Pete Peterson

@@MrDKDIY no no thank you have a good veterans day

I personally think that for a home made unit you did an excellent job! The remark that teflon tape isn't recommended for air fittings is not quite correct! I managed an automotive wholesale tool and equipment warehouse and we built air compressors from 1/4hp up to 25hp, Electric, gas and diesel driven on 20 gallon tanks all the way to 240 gallon and we used teflon tape for all of the connections and we never had any complaints from customers that any line was plugged or leaked. All units were fully ran and tested before leaving the warehouse. I would make one recommendation though and it was mentioned in another reply, that you need to install a drain cock in the bottom of the tank to facilitate draining any water that accumulates in the tank and should be done on a daily basis when the compressor is used. One more thing, any welding done on a tank deteriorates the integrity of the metal which will cause a failure at the weld. However I don't think it's a problem that you have to contend with, with the pressures that you will be dealing with on that unit. Good luck and keep the Fantastic Videos coming, they are enjoyable!

I recommend laying out _all_ the fiddly bits -- perhaps on the melamine -- in their expected relationships _before_ begininning the assembly. If possible, treat sub-assemblies first without disturbing the lay-out, add the completed sub-assemblies back to the layout, and progress through until everything that can be done 'in the air' is done, then hook it up to the big iron. The countrr-top layout doesn't _have_ to use the actual parts (e.g. the air line, the electrical lines), but some proxy would help tyros to grok the recipe and the process.

Right, and such a small tank, you have very little working capacity. Also, it takes forever for the thing to pump up.

Yes, you are right, this is not practicable, also tank can bust due to high pressure.

air intake needs a filter to keep the dirt out of the compressor.

😂

It is oil cooled. That thing can run for a loooooong time. I'd say its pretty quiet to run also

The compressor intake inside the housing has baffles to prevent the oil from being sucked in with the gas. Lubrication is provided by splash within the shell. If he wanted to he could occasionally add a small amount of oil through his air intake tube. kzfaq.info/get/bejne/abunq5CQu8vHeKM.html I had to look it up, you had my curiosity up with your excellent question!

The compressor already has oil in it, hence why you cant use it for spray painting unless you have a oil trap.

I had used an oil bubbler on compressor the intake and a line dryer before the quick connect for my airbrush compressor

NEVER DO THIS!!! IT IS DANGEROUS AS HELL!!! THE COMPRESSOR IS AT RISK OF EXPLODING!!! A COMPRESSOR THAT IS DESIGNED AS AN AIR COMPRESSOR IS BUILT TO RETAIN THE CRANKCASE OIL IN THE CRANKCASE AND OUT OF THE COMPRESSION CHAMBER. A REFRIGERATION COMPRESSOR IS DESIGNED TO ALLOW OIL INTO THE COMPRESSION CHAMBER SO THAT IT WILL CIRCULATE THROUGH THE REFRIGERATION SYSTEM. WHEN THE COMPRESSION CHAMBER IS FILLED WITH REFRIGERANT, IT IS SAFE TO ALLOW OIL IN THE CHAMBER BECAUSE THERE IS NO OXYGEN PRESENT. WHEN A REFRIGERATION COMPRESSOR IS USED TO COMPRESS AIR, OIL AND OXYGEN ARE BOTH PRESENT IN THE CHAMBER, AND THE OIL COULD EASILY DETONATE!!! NEVER DO THIS!!! IT IS DANGEROUS AS HELL!!! THE COMPRESSOR IS AT RISK OF EXPLODING!!!

Ricambi Ariston per cldaie

Screw you

I thought the same thing, however this is very small and mobile so just tilt it to the original top valve and drain the water out that way.

Ok v ery good I well copy it

That's the point: with this configuration, oil will keep leaving up to the point the compressor will get dry and fail.

@@larrywildman4381 I must have missed something. You actually WANT it to fail?

Many many thanks

Nice hobby$$$

Typical answer....... well I can do it better lmfao

No it wouldn't...most of the stuff is free, ; the rest wouldn't come over $50 on ebay, compared to $200 Aus these days for the cheapest one over here

He wrapped the ptfe tape onto the fittings in the correct direction, but it always amuses me when people release the tape from the roll like they're using sticky tape....it's much easier to control if you wrap it onto a fitting from the top side of tape, not the roll side...👍😜 Also.....bit of a concern...I don't see a PRV or NRV anywhere, and no tube connected to the unloader...gotta ask how long it's gonna keep working??...LOL

If you wrap the PTFE tape in the direction of the tightening it will undo the PTFE tape when it tightens your wrong. Have the thread of the bolt facing you and wrap it clockwise then when you tighten it, it will be tightening the tape on the thread

I once worked with a welder who insisted that PTFE tape wouldn't work on black iron pipe. His problem was that in the past he had wrapped a joint in the wrong direction and the tape rolled out of the joint when he screwed it together. He was convinced that it wouldn't work, and nobody was ever able to get him to come around.

I've said this before to others in here but I'll ask here too: How loud is a running average sized workshop air-compressor? How loud is a running everyday fridge? That alone is a good reason make an air compressor out of a fridge compressor. I've thought about modifying an air compressor to use a fridge compressor and watched this video to see how it might be done.

Correcto Ismael. Además pondría una válvula anti retorno entre el compresor y el depósito. No obstante, buen trabajo!!

You are wright!

Amen brother my cousin got himself killed with one of these

You only live once.

I'm surprised you did not notice he was stick welding Malleable Iron pipe fittings he runs a very high chance of the weld failing. More like when, not if it fails. At least I am out of range of that disaster

Richard, that was my only concern also. It’s a high pressure vessel. Incorrect welding can compromise the metal’s elasticity.

Without a pressure relief valve this is an accident waiting to happen. These compressors can do 600psi - 800psi. Looking at the P12TY compressor specification the best you`ll get is 1cfm. You do need to replace the oil that was in the compressor because when it comes Into contact with air and moisture it will turn acidic and eat the copper motor windings. Your compressor will need 400ml of a non foaming mineral based hydraulic oil. Lastly, these compressors shouldnt exceed a 50% duty cycle or a case temperature of 100 deg C as it will degrade the oil. The compressor has an internal thermal trip to protect the windings but the trip rating is based on refrigerant not air. If the trip operates, you can be sure you are not doing the compressor any good ;)

That's what the spigot was for in the middle front.

He did reuse the shutoff valve. I guess he could turn the tank upside-down and open the valve to let the water out. This is the least of his worries, compressor lubrication is the bigger problem, not to mention it dumps air rather quickly and the compressor cant keep up. For a little over $100.00 you can purchase a 6 gal. commercial grade compressor at, Harbor Freight.

Iff you drain it the oil ccomes out with it and will kill it

yep, my only issue & I have built many compressors from salvaged compressors and components. but have also had 1 when I was very young fail due to water inside near where leg was welded at factory. plus got a few free small ones that had rusted out tanks I rebuilt so add a simple drain plug of some sort.
