You’re really talented, man. I can only imagine the UA-cam grind is a long and uncertain one, but I just wanted to encourage you to keep making content and doing your thing, because you clearly have a knack for this kind of work. Mad respect and appreciation for what you’re doing.
I appreciate that a lot! There are times for sure where it would be a lot faster to do the work and not film it, but comments like this are a great reminder there are some people out there that appreciate it.
@@HardAngle Dang fantastic, got a new subscriber for sure!
@@xx-vk5ol love to hear it!
Great build! I like when things are built and restored vs bought. I am building a 5 hp w/ a vertical 30 gallon used tank.
Oh and a tip when soldering, use flux on the pipe and fitting and apply heat to the fitting and the solder will run into the fitting and coat the entire surface between the fitting and the pipe. This will give the strongest and leak free join.
Thanks for the tip! System is still running with no leaks or issues, changed to a 60 gallon vertical once I noticed this smaller tank had pinholes in the bottom and I didn't want to risk my safety. But that tank was also used and restored just like this one.
@@HardAngledoes the generator work good with the 60 gallon tank ? If so how long does it run with a full gas tank in the generator
@@CristianGarcia-g3u I've gotten over 12 hours of run time with a full tank, but the generator was also running my lights, the sandblaster vacuum, and a wood stove blower fan at the same time as the compressor.
@@HardAngle an that’s with your 60 gallon compressor runs good with it ?
@@CristianGarcia-g3u Yes, that is with the 60 gallon tank, since it is the compressor body and electric motor just on a different tank it runs just like before, just takes a little longer to fill up now.
That was an impressive restoration.
You did better than the other video I watched. He got so excited, he started it and ran it for over a minute. Then OOOOPS, forgot to put in oil!
Oof, moments like that hurt the soul.
24:39 great job !
Keep the heat on your fittings when soldering. The heat helps draw the solder all the way in the cup.
Was coming here to say the same thing. Also prevents cold joints. Other than that good DIY project
If you wanna save on fittings sweat the joints everywhere you can. I did this my second go around building one of these cooling loops and it saved me 120 on fittings vs my similar 200 the last time. Now if your sweating joints and creative you can make some interesting parts for very little. I know one step was gonna run me 70 the first go and sweating it it was closer to 20.
That was a Sears Craftsman Compressor under another name Aprox date 1975 had a few of them good unit check tank for rust mine started leaking pin rut holes
I also discovered pin holes on this one shortly after the rebuild. I have since switched everything over to a vertical tank and even did a hydrostatic test on it before building it.
Great video ! Adding links to the components you used would be a nice touch. I'm immensely curious how you're getting 12 CFM ? Because that is fantastic ! Would be helpful to know the specs on the motor and compressor head ! Thanks for the video I enjoyed it
Looks good !! I approve :)
Turns out, this tank had a pin hole in it and I had to get a new tank. Bought a 60 gallon and the new setup is even more similar to what you did! Lol
@@HardAngle Very nice... I personally like the upright compressors more since they take up less floor space 👍
@@fix206 Less floor space AND they are easier to drain due to the shape of the bottom vs a horizontal where it pools along the entire bottom, I am now a firm believer that vertical is the way to go.
I just finished rebuilding my air compressor and due to the modifications i've got a bunch of fittings involved and because of this I wanted something better than teflon tape making sure everything is leak free. I ended up buying a tube of "pipe dope" aka RectorSeal "T Plus 2" and the stuff worked flawlessly. I will never use teflon tape on my compressed air system ever again.
Pipe dope is worlds better than Teflon, overtime pretty much every piece of tape was replaced with pipe dope when they started leaking.
You should hydro test that tank.
This tank ended up having a pin hole in the bottom, I got an upright 60 gallon tank and hydro tested it to 230 psi and all went well. Has been running flawlessly for 7 months now. I agree with hydrotesting your compressors every few years, takes an hour or so and could save your life.
Air pig the other tank so you have more air near where u are working
Where did you buy pump and motor from? Great job
I bought them on the Vevor website
So does that coil of copper sitting in the water end up filling up with condensed water? And by the look of things, once it fills up, its going to back flow into your pump
I have a few hundred hours of runtime on this pump now and have drained many gallons of water out of the water separator but when I took this system apart to move and turned the coil over not a drop came out, so apparently the pump flows enough to ensure any water is pushed into the water separator.
I built a similar sized compressor with a used 3hp motor, used tank, used switch, used electrical disconnect and a used Devilbiss pump that was in like-new condition...way way less than $972.
Again.... $400 in copper and fittings, literally half of the cost is for the cold dry air, the compressor was around $570, couldn't buy this kinda of air output for that low anywhere these days. But I do still respect someone that can build something out of used parts for as cheap as possible.
@@HardAngle I'm good at not adding up cost for home copper plumbing jobs.
It is definitely not my area of expertise
The pedal stool?
Oh, and please buy yourself a crimping tool. I can guarantee a simple tug will pull those wires out of the connectors. I used to do the same but after getting a proper Klein Tools VDV200 crimper, it's like night and day. It crimps so well i can hang 40lbs of weight off a connector and it wont come loose.
I'll look into those, always room for improvement
I was just watching fix206’s video on this and like you mention he uses the water pressure relief valve and I’m trying to cut cost on the water cooling system and that thing by itself is $100. Do you just purge it at the separator? I’m wondering if I can add a separator and the coil to my setup and be done.
I purge the separator every few hours of runtime and pull about a pint of water out every time, I do the tank daily and have yet to have more than mist come out for a second or two, his setup was a lot more autonomous but mine has given me dry air for hundreds of hours of sandblasting so far.
What generator would I need just for the air compressor it’s sell I have same exact setup but with a 60 gallon tank
Generator wpuld be the same its running the same power at the start as it would the emd maybe just runs a few extra minutes.
What size pulley you use for the Electric motor ?
Go online you can get the size you need
Othe rthan the soldering, heat the joints as others have mentioned. Nice DIY project
dude like that system, can you leave us a link to where you bought the motor and pump thanks
Should of stayed with the old pump, those alloy pumps are just waiting to to get back to the junk yard.
That copper gets really hot! Be careful it will get weak and loose in time. This will be like getting shot with a 38 cal. Be safe use compression joints save yourself and your family.
This is good advice! Air systems always make me nervous in general, an air compressor is basically a giant bomb after all.
I think it’s required to say it two or three times differently. At least I do. Vevor, veevor. Who knows how it’s pronounced. They are usually good though.
speedair compressor
No heat shrink on wiring exposing copper, no tank drain on the bottom of the tank, wrong crimp fittings and lack of crimp tool for wiring.. and if you wire motors off of 240 when they can they will be more powerful.. keep the heat on the pipe and fittings when soldering plus use flux.. you can get pads for the compressor that stops a lot of vibration.. if you get a power steering cooler radiator they cool the air plenty as long as you get a 2 pass thats a decent little size and they’re only 40$ at most. Powr steering is usually 3/8 line so some adaptors and a little pipe fitting and they work great.. using a bucket of water is just too much to keep up with and as long as you use the power steering cooler and put it below the point where it enters the tank with a oil water separator before the tank than not much moisture will get in the tank but still need a drain.. gotta keep tanks drained. From the amount of crap that was inside that tank from the sound of it im betting its pretty rough inside.. not good..
Just going to say most of the stuff you suggested I actually did... yeah the motor wiring could have been better but it is wired for 240, the tank did have a drain, I didn't build the tank anyway a giant corporation did, everything was soldered with flux, and the bucket of water was insanely cheap, had better flow, and will keep the air cool for hours of continuous use and when heat soaked can be dumped out and replaced with cold water in just a few minutes.
Your a dick
That old electric motor just needs sevicing.
Don't worry, I gave it to a friend who wanted to rebuild it, it did not get tossed in the trash
WHY DIDNT YOU JUST BUY THE 459CC PREDITOR INSTEAD OF THE GENERATOR???
Because the generator would be handy anyway. I got a car lift a few months later and that generator powers that as well.
100% duty cycle is a dream . I highly doubt that will run a sand blaster your gojng to over heat the pump or motor in no time flat
I ran a sandblaster for 15 years using a 2hp 20 gallon SEARS compressor.
Surprisingly it runs my Skat Blaster great, have done up to 5 hours of straight run time without issue, had a few hundred hours on it now.
So you paid 75$ pretty much for a old tank . I’ve also been cursed with air compressors every used air compressor is usually messed up people don’t usually sell air compressors if they work good
I learned this lesson the hard way lol
