Make sure to warn people about the dangers of welding on a propane tank without proper preparation as consequences can be deadly . Thank you for the great video .
when u live 20 miles from the nearest store of any kind, u horde certain things. lol. i didn't go 250, but i did build my own 120 gallon. because back before u could get good battery powered tools there was air, plus i like to paint. thank for the video bro, u showed me things i could have done better, i appreciate it. even though I'm an old man now, i still love to learn new things.
You're doing a really nice job Randy. I have a Porter Cable 60 gallon compressor and it looks like its the same as that one. One of the reed valves broke when it was only a few years old. The cheapest repair ever. That part was around five bucks. You're doing great.
one recommendation for a tank of that size Randy: put an automatic sneezer that kicks off at 150 PSI on it so the condensate drains regularly... save yourself the hassle of having to do it manually all the time
Poor man’s version for home shops? Crack open the drain valve so it is always leaking. Unless you are running Dailey a weekend diy shop can use this method.
Something I've seen done in another video is add an airline in between the air filters and the piston cylinders and pipe that hose through a 5 gallon bucket of cold water to cool the incoming air down before it hits the pistons...that causes any moisture in the outside air to condense BEFORE it hit the tank or shop tools... They built a water trap and bleed valve into the condensing coil at the bottom of the bucket so they can bleed the condensed water out into the bucket... Add this mod to the system and it should significant;y increase the lifespan of the compressor and tank as well as any air dryers in between the tank and the shop tools...
@@HolzMichel By running the air through a cooling loop, it forces the water to condense out of the air BEFORE it hits the compressor...so by the time it hits the compressor and then the tank, it's already dry so there is nothing to condense out as it cools in the tank...
All the crud in the valve area appears to be caused by using detergent motor oil, compressors need non detergent oil. The temperatures in a compressor are much lower than an engine so the detergents don't get hot enough to properly do their job, so the crud forms
That really looks good. That's all you need. I picked up an extra Ingersoll tank to use in addition. Topping about 140psi. 3/4" black pipe all over the shop. Really nice to have. Cheers! -Tom
I'm thinking the gaskets weren't sealing or just deteriorated over the years, everything else looked pretty good. Those dual piston compressors are much quieter than the single piston type. Nice job.
Without having studied pressure vessel welding I hope you might add comments and considerations on one of the future videos of this build. Looking forward to the next.
I worked for the company that built that tank, I’ve personally seen one take 1500 psi of water pressure without failure, and every tank is pressure tested to 500 psi and checked for leaks. A 150 psi of air pressure shouldn’t bother it in the slightest.
This is why I like Quincy "QR" compressor pumps - they've been around since WW2, and are basically unchanged, and are still in production. Rebuild kits are easy to find and the base castings are cast iron, not aluminum, so they last forever. Downside is cost - a new QR pump can cost as much as a whole compressor from IR.. 😵
We are replacing replacing a 45 year old crane that had a Quincey air compressor . They wanted the new crane to have a rotary screw air compressor . The control board Alone is probably 2k. I speced out the Exact same Quincy ! The pressure switch about 50 bucks.
Pressure testing a used tank with air is not something I’d ever do. The amount of stored energy in that tank at 100 psi is enormous. I’ve seen what happens on tanks and pipelines with even moderate air pressure. Hydro testing is much safer. Fill the tank with water and pump up the pressure to the test limit. Eve n a slight leak will just dump a small amount of water. No explosion.
Good video and your knowledgeable no doubt but just a little advice in case you haven't messed with a many small atv,motorcycle engines which the compressor motors are made like the jug is tapered on the bottom so a ring compressor is not needed just offset the rings and tap the jug down onto the piston.
Hey man, not sure how I got here but I found your channel! I really like your energy, especially at the end when you showed the end result admiring your work 😁👌 Damn, I really need to learn how to weld! It opens so many more opportunities and ideas which usually is the thing that hinders me 😴
are you setting up inside or outdoors. Outdoors will give you nothing but trouble with moisture in the air. Inside will give less trouble. And don't forget the autodrain to remove condensation. (heck I would put 2 in just in case one fails)
Yes! This is so cool! Will the tank smell of propane? A friend's dad used a natural gas tank and evrytime he ran it,it reeked of the chemical additive for the gas. Love this build!
Thank you. Yes there is the smell. I purged the tank with a shop vac in pressure mode 4 times for 2 hr each time. This removed almost all of the smell.
yes, you fill the tank completely with water to purge the propane.. then you drain the tank and can weld to your hearts content. edit: and you need to leave the fittings off so you don't create any adverse over pressure during the welding
That looks great, 2👍👍up. I do have a question... I'm not a Machinist but bought a mini mill and lathe as a retirement gift to myself ( with wife's okie dokie ) to learn on in my shop. I need to get a granite surface plate. Is there a difference between a granite surface plate you would buy from a tool manufacturing company and just a piece of granite countertop? My concern is,.. is the countertop actually flat enough? Or are they something to stay away from? Thanks in advance and.. Have a Jesus filled day Greg in Michigan
Counter top looks flat but they are not. For under 100$ you can buy a new 12 x 9 x 2 B grade plate. This is probably large enough for to work you will do. For under $200 you can buy a 24 x 18 x 3 B grade plate. This is at MSC. Thank you Greg.
Standing under unsupported hydraulics is highly recommended. 🤣🤣 But it does sure look good. I don't know if I would of not made a smoker out of that tank instead tho. That's a lot of Air volume for a small compressor.
Was there any preparation done to the tank before welding? I was wondering if this would be risky... I could you some enlightenment on this! Project is looking great! Thanks for your time and sharing! 👍😎✌️
In another comment someone mentioned water filling for pressure testing. That would help clean it out more thoroughly than a vacuum, but it would also be a good time to weld while it’s full of water putting a bit of helium inside to purge air contact with any propane remnants would also work well.
Great job leak stopping and converting to air. But what the heck kind of John Deere man paints a tank green and no yellow on it? Maybe just a yellow racing stripe down each side? 😉😉
@@anthonyhumbert8787 The number of compressors has very little to do with the size of the receiver. The number of compressors or the volumetric output of the compressors is all dependant on the volumetric load on the system, the receiver is sized more for the surge capacity that may be required on the system. In this case the compressor is large enough to meet the needs. Running only a few times a day for 15-20 min. This is very efficient for the load. Smaller receiver the compressor would run 10 or more times a day. The large receiver also allows the air to cool and drop out extra condensate, producing drier air to the load.
@@RRINTHESHOP yes for low volume use it's ok. The problem would be if you ran a high volume tool for an extended period. Something like a big impact, paint gun, media blaster or multiple low volume tools at once. Home shop use you would probably be ok.
Dang, very nice work! Pine straw floor for paint booth, haven’t seen that before. Any help on where I can get the Moyco lapping abrasive sheets. Tried a quick Internet search with no luck. Thanks
Has any engineering been done on propane conversion to compressor tank as I think propane only has maybe 10 psi static as compared to 150 psi dynamic loading on a compressor tank.
Hi Randy I believe you live within driving distance of me couple hours I have a 2 cylinder two-stage compressor pump in real good condition off a mobile air compressor was powered by 16 horse gas motor or you could use a seven and a half electric motor to drive it if you're interested let me know cheap with pulleys complete. JM Also it's a 32 CFM compressor make a hell of a shop compressor
Well that's a nice little air compressor you got there looks a little bit of cleaning and it should be good what size tank are you putting it on thanks.JM
@@RRINTHESHOP well Randy it's been here a long time for some reason nobody wants it it's probably too big you come across somebody would like to have it let me know thanks
@@junkmannoparts9696i would love it if you want to still get rid of it or even still have it not sure how reply work but hey never hurts to ask thanks to all the knowledge droppers i pick up all or what i can appreciate it
Randy, where are you getting your braided flex lines that you are connecting your compressor outlets to the tank? I have a need for something smilar and cant find a reasonably priced option.
These are actually used lines off of a Sikorsky S-64 Skycrane. My son works on them. They have to change them out on a time basis. Still plenty of life in them, they are rated at 1500PSI and 450F. Good for what we are using them for. Thanks Christian.
@@GenXPessimist Yeah we use them for all sorts of things. My son has them in is off road truck for fuel lines. I have them for air lines on my milling machine.
Randy, you sound like crap. Are you OK? I hope you're not suffering with covid - if you are then go get some of that medicine they're giving out when you get tested. (Pfizer’s Paxlovid ) So, besides being concerned for your health, I like what you're doing with the compressor - Those old Fan/Flywheel/pulleys are my favorite with older compressors. Stay safe and well :)
Oh yeah, then not now. I have had Covid twice. No Vacs and none of there drugs. All fine and in great health. Thanks for your concern. Yep I love those type also. they really smooth out the pulsations of the compressor.
Just look at the cylinder bottom and you can see a 30 degree camphor and that's to assist in the compression of reinserting the ring when yo slid it over the piston. You shouldn't need any ring compressor. Also the normal pressure in the tank is between 150 - 200 psi and wouldn't be considered high until you got 300 psi or over. Nice job.
