Let’s Make a Pressure Pot

[@donferron5352]

Received my 15L pot today along with the shutoff valve. I had to heat up the suction tube and use a pair of vise grips and a hammer to remove it. They used some type of thread sealer. The same with the elbow. I took it to ACE and they could not match the thread for a replacement plug - nope. We don't have a big box here in town. Can't add the shutoff like you did, because the handle can't get past the gauge. I tried taking the gauge off - nope. Tried removing the T - nope. I have questions pending from a couple of weeks ago and their initial replies have nothing to do with the questions. Terrible customer service. Here is my solution I will cap the top T and put a 3/8" ball valve on the elbow. I got this idea from viewing one of their videos for the relief valve. Parts on order from Amz. Love your videos!!!! Blessings, Don I received the parts from Amazon: an adapter for the elbow from 3/8F to 1/4M to assemble the shutoff I already had and a 1/4 cap to close off the outlet that would have been for the spray gun hose. No matter how many wraps of Teflon tape I used, the elbow still leaked. The manual has instructions on how to fix a leak, but I decided to use it on the threads. I will know if this works tomorrow. Some of the issues could have been prevented if the gauge had not been pre-assembled like yours was. Not totally happy with the clamps chipping the lid. Thinking about a solution. All in all, I am pretty satisfied with the quality, it is just that customer service is non-existent.

I have used these pots for resin casting for 30 years (with some replacements). For leveling the bottom of the tank I use cardboard 9-inch cake rounds. They fit great in the bottom and are easy to dispose of when they have spilled resin on them.

[@PawPawsWorkShop]

That's a great idea! I typically just use a piece of plywood. Thank you for your suggestion

[@ericeinsmann5559]

I finally saw the benefit of the pressure pot.. A guy did a side by side comparison between a pressure pot casting and without using clear epoxy. To me, the difference between the two was like water and soda pop. So now I understand the need for a pressure pot. 😊

[@PawPawsWorkShop]

Awesome, yes, pressure pots are very nice.

[@TheGeekBox]

Thank you for this! I literally just brought this exact paint gun for this reason for my first pressure pot and was getting worried about how I would convert it and how hard it would be lol. You're a life safer Paw Paw 😄

[@PawPawsWorkShop]

Awesome! Glad the video helped you.

[@TheGeekBox]

​@@PawPawsWorkShop thanks I'll update you now I have it. Can't get the paint pipe off atm. Mine seems to be lodginges in tight lol

[@TomPearce]

Hopefully you figured it out by now, but I found zapping it with a heat gun loosened the glue up and allowed me to pop it right off, though mine was a harbor freight pot.

[@TheGeekBox]

@@TomPearce yeah I got a metal border I the end and works a treat. Thanks for replying!!!

[@ericeinsmann5559]

Very helpful video! Forgive me for another question.. Do you have a video for pressure pot basics? I've never used one before, but I have a couple of ideas related to the lathe that I think will require a pressure pot and clear Epoxy. Thanks again and I hope you are doing well!

[@PawPawsWorkShop]

The pressure pot is easy. Use approximately 40 psi and I usually let it sit overnight.

[@dblackb99]

As I noted in an earlier reply, I think the threads on this pot (I just bought one as well) are BSP and not NPT. However they are close enough that a male NPT threaded component can be forced into a BSP female although not recommended.

[@PawPawsWorkShop]

You may be right. Thank you for sharing

[@DrHumperdink]

So I just got one of these and noticed the threads were off compared to NPT and saw your comment. I must say I didn't before know about BSP so I had to look it up. I've seen there's 2, BSPP which is not tapered and BSPT which is tapered. Do you know which it is? Also, do you know where to get those fittings in the US?

[@GamerGoop]

Thank you! Really great video Paw Paw!

[@PawPawsWorkShop]

You’re very welcome. Thanks for watching

[@Vija_W]

Thank you so much for the video, it's very helpful and easy to understand! I'll check out your other videos for sure :)

[@PawPawsWorkShop]

Thank you very much. I appreciate you visiting my channel and I am so glad that this video helped you

[@44mod]

Great video thank you for your time. Thumbs up!! Just a thought, when I am not sure about threads. I pull out my metric and standard thread gauges. The pipi that came out would have been perfect to check and see what type of threads to use with those thread gauges, probably a NPT thread . on the other hand if it fits then no problem.

[@PawPawsWorkShop]

Excellent. Thanks for the comments

[@bobloy4684]

Is there a description of the parts you purchased to adapt it?

[@PawPawsWorkShop]

The parts list is shown in the video itself.

[@DamienDemonSlayer]

Thank you for the video PawPaw it saved us a lot of time! Of course, it took us more work since you have much larger forearms than us 😂

[@PawPawsWorkShop]

Glad it was helpful!

[@timothydonlin4740]

Great tuturial as usual! I was just wondering though if you couldn't use the air intake valve to also release the he pressure once the air hose was removed?

[@PawPawsWorkShop]

Most like yes. It will depend on the manifold. Some may have a one way valve. Mot of the inexpensive manifold should do that without a problem

[@rmaniak96]

man thank you so much for that detailed video ! i'm still a newby but it gives ideas, origanlly i looked into buying this for airless painting for my house but now i'm even thinking about using it for sand blasting or even washer for my motorcycle, i'm wondering if its possible interm of psi settings and adapters or even using it as a compressor ! what do you think about all this? and last question, since i don't even have a compressor, do you think there is a portable compressor with a special adapter that i could use to prime this tank over and over again? even something manually like a biycle wheel pump with the correct adapter? thanks

[@PawPawsWorkShop]

While there are many options available that may work, please be very careful. Pressure pots are primarily used as paint tanks and are limited to a relatively low pressure. Depending on the tank, you will be limited to 40psi or possibly 50psi. Don’t exceed what the tank recommended pressure is on the label of the pot.

[@rmaniak96]

@@PawPawsWorkShop thanks alot for warning me ! ill do some homework to see what can be used then with that pressure pot

[@gustavotobon7042]

Hello, I really loved this tutorial. You were so thorough with the i formation. I have decided to buy this pot and follow your i nstructions. I was able to find all the pieces except for the cap you used to seal the paint hole. Can you tell me what size and thread I need to buy for that. The other thing is what type of compressor I need. I really appreciate it

[@PawPawsWorkShop]

Thank you, I have found that the various pots will have different threads. The Chinese pots most likely will be different

[@TheGR4N4D4]

Quero começar agradecendo pelo ótimo vídeo, obrigado por compartilhar. Eu comprei um Tanque de Pressão muito parecido com o seu, exatamente para trabalhar com resina, mas estava com medo de tirar a haste interna de metal e o seu vídeo foi muito esclarecedor, ajudou muito. MUITO OBRIGADO!

[@PawPawsWorkShop]

You’re very welcome.

[@donferron5352]

Enjoy your videos! Would you have a hardware list for this conversion? My VEVOR 15L tank will be here in a couple of days. EDIT: No need. Read the above post.

[@Edge_Walker]

Literary just got it for pressure chamber use for resin. Thank you! Where did you get the plug tho?

[@PawPawsWorkShop]

Thank you. The plug is found at the hardware store or big box stores

[@user-vz8pb2fk5d]

Why the second valve to release the air from the tank ? I just capped it instead of putting in a second valve. I use the first valve to let the air out ( the same valve I use to let the air in). Am I missing something here ? ( Am new to this ) thx

[@PawPawsWorkShop]

It’s not necessary. It’s just what I had on hand. I did not have a cap for it so I used the valve I had on hand. Thanks for watching

[@gregjohnson8486]

Very informative video. Thanks for sharing. I did wonder why you can't use the first ball valve to empty the tank instead of having a second valve for that purpose. Can't you just disconnect the hose and slowly release the pressure with just 1 ball valve?

[@PawPawsWorkShop]

There are numerous ways to setup the pressure pot. Just like I show many ways to make cabinets for example there are many ways to set this up.

[@jessehughes3741]

Should you add a second regulater with gauge and have 8 to 12 psi to pot and 25 psi to gun ?

[@PawPawsWorkShop]

There is not need to add a second gauge

[@QuiltersHandyman]

Could you also use it as a vacuum chamber to stabilize wood??

[@PawPawsWorkShop]

It’s best to use a vacuum pump

[@QuiltersHandyman]

I'm sorry I made some assumptions....I am interested in stabilizing some wood for pencil blanks, etc. I have a vacuum pump I use with my lathe. I was referring to the chamber.

[@blazegbs]

Yes, you need a couple of different parts

[@janinanelson1758]

Great video. I just got a similar paint tank from Princess Auto but I can't get the tube or elbow off. It appears they really don't want anyone to modify it. It's got something reddish orange around the threads. Looked like an o-ring at first but now I can't be sure.

[@PawPawsWorkShop]

That is most likely locktite. Yes, that will make it extremely difficult to remove.

[@pippadee]

Great tutorial, thank you! I have just got a vevor pressure pot for resin casting but the intake pipe is *not* coming out. We've tried to dissolve the thread glue and have used a heat gun to try and melt it, but it won't budge at all. Pipe wrenches aren't working because they won't grip the pipe. I don't have access to a vice or tools to cut the pipe- any suggestions to get it out? I'm going a bit crazy! TIA

[@PawPawsWorkShop]

Sometimes they use Red Locktite and it will not come out. You can add another connector to it.

[@pippadee]

​@@PawPawsWorkShop I tried using some locktite dissolver (the super glue one), adhesive remover and acetone but ended up buying a pipe cutter to cut most of it off. Whatever they use gets 5*s from me because it does its job VERY well!

[@JBGecko13yt]

I will be doing this, thanks!

[@PawPawsWorkShop]

Great, have fun with it.

[@lcmmassa8571]

Many Thanks Paw Paw Workshop! Ive wanted and needed this pot for 8 yrs. Too afraid of the pressure exploding, Ive drug my feet. No More. Great tutorial! Im heading out for a paint pot. I need a big one. 🤣 where and what sizes are available? Ill check your website for an address to mail a figured wood Thank You! 🙏 All the Very Best! Lcm,GWW

[@PawPawsWorkShop]

Pressure pot is a great addition for working with resin projects. Follow the safety rules as you would with any other tools

[@todayintheshopbanksy5904]

did you need the 2nd valve? why not just cap it off. Then use the fill valve to release the pressure

[@PawPawsWorkShop]

No, you do not need the second one. I put it on because I had it and did not have a cap. Another trip to store that I did not want to make. There is always another way to do things. I like to use the parts that I have first before buying new. Thanks for the question

[@Edge_Walker]

Dont be dumb like me- if you think your pressure chamber is leaking, try turning the black knob. It answer for how much and how fast it lets air out. Fiddle with it and see 👌😌 you can get 45 psi even with a bike pump

[@PawPawsWorkShop]

Yes, the black knob is part of the regulator. You can adjust the pressure to set it exactly to the desired pressure. However, you still can have leaks. The lid gasket as well as the fittings all could leak.

[@zfsachsag]

Hey! Thanks so much for this video - it certainly helps us out here in Canada as this seems to be the readily available pots around. A few questions if you don't mind: - What was the dimension of the plug you used to replace the elbow? Is it something one can find at a Lowe's? - Could you share the names of the other parts that you did purchase? Apologies for the newbie questions - I'm not the best at diy, but really want to make this pressure pot :)

[@PawPawsWorkShop]

I showed all the fittings that I used. Different pots may have different fittings. Lowe’s or any big box store or hardware store will have all the parts you need. If possible take the lid to the store with you

[@SamDoehren]

Hi Great tutorial, about to buy parts for this conversion. Is the plug you replaced the elbow with 1/4" or 3/8"?

[@peterbennett4324]

No point for a 2nd ball valve or the regulator, the more bits you add the more places to leak. Just watch you gauge as you add air and turn of ball valve at desired pressure, if you go too high the relief valve will pop. To let out the pressure just open the inlet ball valve.

[@PawPawsWorkShop]

Yes, that is true. I had the ball value and did not have another plug. Lol. I use what I have

[@reveriesyndr0me]

hello paw paw, did the pot come with the plug or did you have to buy it separately? :)

[@PawPawsWorkShop]

Yes, you need to buy it separately

[@Taco274x4]

Just curious, can this be used as a water pressure test tank? Like for example, testing GoPro watertight cases and such? Finally, thoughts about taking it to 60psi as that would be "my" max pressure setting. 50psi would actually be fine, but what about 60psi as a max? Obviously just as long as it is well below the 80psi max as I agree it would likely not be a good thing to take it to max 80psi.

[@PawPawsWorkShop]

I see no reason why you could not do this. Never max the pressure on your tank. It can be unsafe.

[@Taco274x4]

@@PawPawsWorkShop Thank you for the reply. I know to be careful with the pressures. At work, I use a pressure tank similar to this.We pressure test "diver communications devices" at approx 65psi. I just want to setup something similar at my home to a pressure of 60psi. If 80psi is max, then 60psi is well below that max and this thing would work perfect for me. THANK YOU sir and I subscribed to your channel. Very helpful videos too!!! Keep up the good work!!! Have a blessed day sir.

[@jeremycatches9766]

I feel like the second valve is unnecessary as you can unhook the hose and release the pressure with the same valve you used to let the air in. I will verify and post again. EDIT; so I did a little research and I think the second valve is necessary, but not in that position. The problem is you don't want to release the pressure though the regulator because it will allow moisture to get in the regulator. Instead you need to have the second valve before the regulator somewhere.

[@PawPawsWorkShop]

The value is not totally required. It was required in my situation but I did not have a plug. There are multiple ways to accomplish the same thing. Thank you very much for visiting my channel

[@ryjacrafts4797]

i think i broke my barometer. its not moving when i pump in air.

[@PawPawsWorkShop]

Time for a new gauge. One thought, it might be the regular also. Check to make sure

[@alexormandy3353]

Hello! I have a question about the threads used by the manufacturer. Are they all NPT/FIP threads? I know you said about the adapter for the air inlet but I was specifically wondering about the plug that you used for the paint outlet. Thanks in advance!

[@dblackb99]

I just got one of these and I'm pretty sure the threads are BSP and not NPT. They're close, so it's possible to force NPT male into BSP female, but not recommended.

[@canadan350]

I have the Vevor 10 gallon pot. The pressure relief valve releases before it should. Do you know if it's adjustable? Thanks.

[@PawPawsWorkShop]

Usually there is a screw adjustment to regulate the pressure release
