CEO of particular
i can tell by your style and patience, youve really thought this project through
thanks and have a new sub
I appreciate that!
Tinker, you are a legend, I knew there was an easy way of making a PC gun, just didn't know where to start, and as others have said not much on YT about homemade ones, I have ordered the parts and will be making one up very soon.
.
Thanks for the feedback. Have fun with it.
Great great explanations, have not yet looked at the second generation, but if at same level of clarity, it will probably motivate me to make my own !
I built a powder coating oven, and I have been trying to make a powder coating gun, with no luck, then your Video Pops up details leaving nothing to ask you about? Man you rock!, I thank you very much for this very detailed explanation, I happen to have all the parts except the dc-dc step down buck, I've placed my order just now, because I don't wish to destroy my taser module.
Thank you again
You're welcome. Have you seen my other videos? 2nd Generation gun? I have made some improvements you may wish to take advantage of.
How big is your oven?
@@tinkersmith4615 Going to do so right now, my Oven is quite small 40X40X40 Cm, and btw, I've subscribed to your channel :)
Really enjoyed your videos explaining the electrics and the gun..Subscribed
Thank you very much for the excellent video. A hug from Brazil. Congratulations!!!
Thanks mate
Thanks for this awesome video and explanation of the powder coating process and components. I plan on using it to powder coat jewelry; so we're talking about small pieces. The gun maybe small as well or I might make a charged brush to use in some instances. I will let you know how it turns out. Cheers.
Keen to hear how you go. Cheers.
You are a particularly particular person.
Ah, you picked up my particular nervous tick. I always get one each time I speak off the cuff and they seem to be different each time. My most embarrassing one was when I did a week long conference and I kept saying "and the like" as my pregnant pause people started taking count. :-)
Great video like the others i too have ordered the parts. I was looking for eastwood powder coating unit and saw your video. Here in my country eastwood cost P14,355 converted to us $ its around $300 with shipping and the high voltage module and dc-dc converter with adjustable power regulator with digital display is jus $10 you saved me a lot of money and learned something new at the same time. Thanks again and good day to you mate!
You're welcome mate. I hope you have great success with it.
@@tinkersmith4615 i'm just curious. If you don't mind me asking would this dc-dc work shopee.ph/DC-DC-Buck-Converter-CC-CV-Power-Module-1.2-32V-5A-Adjustable-Regulated-power-supply-Voltmeter-ammeter-i.310237530.4253495594
Thanks again.
Yes, that should work well. The most important thing is that it can limit current. I tested these high voltage modules by varying the voltage and current to see which was limited first. It was always the current. For example, if I set it at 2.5A the voltage would only get up to 3.3V and not exceed it.
@@tinkersmith4615 Got it much appreciated. I'll be waiting for your next upload.
Bravo from France
Thank for the électronic tip
Great video
You're welcome!
Very well done!
This is exactly what I was looking for! I am going to replicate it! Thank you very much!
You're welcome. Have fun. It is amazing how well it works.
Great video, with detailed explanation! Does the part that is being powder coated need to be discharged in any way before you can touch it ( and put it in the oven?) I see you touch the tip of the gun to the grounding clip before turning the metal piece around. Regards
I discharge it to be sure. I think in the video you can hear a little tiny zap when I discharge it. I do it just to make sure. I did get zapped once when it was all on and live. Wasn't paying attention. It made me jump but didn't hurt.
Thank you for sharing this i ordered the part and when they arrive i will be 3d printing a whole gun to accommodate the electronics,i hope it will perform better than my eastwood gun 👍👍👍
It would be awesome if it did perform better than your Eastwood. Would you ever consider doing a comparison video?
@@tinkersmith4615 i will certainly do i will send you the link and link your video in my channel
@@tinkersmith4615 I would love to see that guys. Very interesting.
You are very useful man! I am asking because read both for tribo and corona powder coating. I wanted to make tribo gun as it is without high voltage. And they use teflon/PTFE/ which polarized the output tube negative. It may be useful.
Thank you for this video! I now feel confident to give it a try. Doesn´t really matter if i fail since the cost is very low. Here in Sweden powder coating guns is pretty expensive. I have been thinking for a long time that a powder coating gun can´t be rocket science since it`s all about charging particles.
Thanks for sharing this very informative video.
I just had to hop back on here to say that I've built this, just as described, and it works a treat! The only scary part was the arcing across the 'hot end' wires when I first powered on. I had to route the wires to opposite sides of the project box to keep some distance between them, and there is a considerable gap needed between the gun and the ground, otherwise it will blow a hole in the powder on the part. I have my air backed right down to about 25 psi, and a small toaster oven at 200 (the recommended temp of the powder). I pre-heat the part and spray onto it hot, then bake for 10 minutes. My technique needs some work - don't touch the powder on the part, because no amount of over-spray will get those touch marks out.
Great! Thanks for the feedback. 25psi is pretty high. I only use 5-10. The arching sounds like the insulation on your wires is too thin. Perhaps trying the next gauge of wire.
@@tinkersmith4615what's the truth about these do they actually last or blow after useing them a couple of times meaning the static ark generator ?
Mine has lasted ages. The current limiting device that I used prevents it from blowing up. Without it, the high voltage unit will destroy itself. I know because I went through a few to start with when the wires touched.
Great video, you gave a very detailed explanation!
Thank you. Glad you enjoyed it.
thanks for all your videos and very clear explanations. so the buck converter power supply is only there for protection in case you short the output of the High Voltage module? it will work just fine with regular power supply as long as you be careful not to short the output.
Well, yes and no. I have done further experiments and found that the amps is the most important factor. Of course in an electrical circuit both volts and amps are related but I have found that if you had to adjust just one, amps is it. So, to answer your question, yes provided you don't have a power supply that will deliver to many amps should you increase the voltage too high.
A resistor at the output would also limit current
The psu for the Eastwood home powder coating gun, has 1 component… a voltage tripler from a old style crt tv..
one of the best demos on youtube, brilliant. what PSI are you using? I don't have a compressor so was wondering if a variable PSI tyre inflator would work?
Hey Mate, great video!! Cant wait to give it a crack 😊
Thanks mate. Have you seen my second generation gun? Same power unit, better gun design. Works much better. Have fun.
Big thanks to you sir.
Great video !!
Thanks!
To begin 👍👍👍 excellent video and explanation of the components and how they work together my question is is it possible to take the voltage module and extend the voltage knobs through the modular box to transform your initial set up into a dual or multi voltage system?
Thanks. Others who have wanted to do what you are asking have simply used modules such as these: www.ebay.com.au/itm/193663506025?_trkparms=ispr%3D1&hash=item2d173e9669:g:6rgAAOSwr0VfYGCG&amdata=enc%3AAQAGAAACoPYe5NmHp%252B2JMhMi7yxGiTJkPrKr5t53CooMSQt2orsSd3M8ngECaRA0SmyU4KT%252FnrADFkIihSg4QXIDwcLrPUwxJjuxRqKWW9mpCUd39eaqUsmgGEx9eHGqOkTahSzi1kOFtmndCsm%252FRgkr2l1O%252F52HTjwM0YlO9ySJ8rvXH%252Be3eG3tC6kOSOLDfVwLjD6ZXWjOKZJba70vm2%252BNUVMff00v2SJZGI7f9qi1bF%252Bx8curwuW3kXv1sQoCjdJvz6vDNeqdyVKH7aE8bzMjLBkHpK%252Bu4WpBdRKLWJkDvF3KKruX89Ca5bt9a3L4le3XMhM5KjmKkoIlJ0AAT0fk%252BohoKsB5SwgVC6NlsAILwOTl97ElSQ8HAjhXgIjF0493prQauuTWEIWF8FaG%252BiTJqIywsAIy9Xxk1TGLOfbcwWQxupz%252FUgF61Us8Bxn4J19mZKEahHn87VKaFx52SuS6TqHXv%252BaZrTQV6Buv9S2rICCEEmMhunKNdU2RMIxN9uWrGzCW9s8hR7Z%252BKiAAV8PpTFfx39IG7eaNskN%252BJ%252BblNcK2LqQzlr1PytmHFHyTbcSNVVWF30I5Tr6M639x5xvYni9MYi0bss4CRhs4O87ZAqLoJnnWdgh9kgR4NdufXuBkp0BKDGFRzB4WHarvlB8QK5hHdFkKspcByN%252BST2ilmFAiaA7jDHGFgW3lW%252Bt7c4uXS%252FluR6QAusmh9Mmn%252FgRyq0D%252FPVc3bf86oiopw5MqrUxbCnUhbvw7TeHJOF8SFlGI9oDsJLUWexBbBTqS1zpgZRpmyqVoIvSWw08O3s2MwAHwkgICKMvQt8DYdrK4Ehb%252FAVbeoJvVUrU%252Br%252FkSpKJdH%252FHwjCchtMi8FSDLPcaD9v2%252BaZ17AtGHbgjz0Zs90BF3fMO%252BNg%253D%253D%7Cclp%3A2334524%7Ctkp%3ABFBMzvXRq91f
Thank you very much. Great video
Hello Tinker,
What can i say about this video???
Absolutely great i think, you took the time to make this video so i can make my own gun for a few euro's. I think you did great!!!!!
Thx a lot for your video mate and keep on going..............
Eric from the Netherlands
Thanks for the great feedback. I have learnt so much from other people's TH-cam videos so I thought it was time to give back.
Thanks for the uploads. I am in the process of building my own. I have read and seen that to get the best coat on you part you need a good ground. How do you ground your parts? Thanks
The only ground I have needed was connecting the work piece to the negative high voltage wire. I too have read about people driving earthing rods through their shed floors into the ground and connecting them to the negative wire and work piece but I have not needed to do so.
@@tinkersmith4615 Awesome! Good to know. Thanks for the quick response. I look forward to more of your videos, they really are first class.
first of all I Would like to thank you so much for your explanation and it help so much and you made me happy. because I bought one but aramex didn't send it to me.. I will make one now after I understand every things thank you so much
Happy to help. Thanks for the feedback.
Excellent. Parts came in today. I'm using a 12v 4.2a Mean Well power supply along with what i think are identical buck and boost modules. Everything is assembled inside the case of an old ATX power supply that died a while back and i decided to keep the 120mm fan in the case to cool everything. Everything is assembled, all thats left is the first test which i'll be doing in the morning. It's a bit late to be charging up my 26 gallon compressor in the garage lol.
Awesome. I'm super keen to hear if you can repeat my results.
Any chance you have tested your gun yet? How did you go?
@@tinkersmith4615 I initially screwed up and mounted all the hardware inside that old power supply case and between that and making the leads too long, i fried one of the two boost transformers because it arc'ed through the insulation to the metal of the case. I then swapped everything along with a new voltagte booster into a cigar box and nothing.... then i realized i didn't have the clip on the electrode sticking out of the top of the gun and once attached, the powder flowed and it stuck to the test part amazingly well. Better than i had imagined in fact. The powder i used was the cheap harbor freight stuff. I went with the semi-gloss white since matte black the only other choice and here are the results.
i.imgur.com/RJriYCF.png
Just a simple, very old spring clamp made by the Cincinnati Tool Company probably around 70 years ago. It came out real good with not much orange peel. I'm going to try again running a heavy gauge ground wire directly to the house grounding rod which is in my garage also. From what ive been reading, the better the grounding, the better it will come out.
The only thing i've been uneasy about is the safety of running such high voltages through standard 300 or 600v rated wire. I know its low current which makes it safer. This stuff for example is rated up to 30,000vdc. smile.amazon.com/uxcell-Silicone-Gauge-Electrical-Voltage/dp/B01IX44Q36/ref=sr_1_3?dchild=1&keywords=high+voltage+hook+up+wire+kv&qid=1610172864&sr=8-3
Looks pretty awesome to me. Thanks for sharing.
I haven't had too much issues with orange peeling yet but that is because I am only just starting out. When I look at articles like this (www.tiger-coatings.com/blog/default-title-5) it could be any number of issues.
You really like the word "particular"... count how many times you used it in this video...
Very good
This thing is so awesome!!!
Are you saying that after having built it and tried it out?
@@tinkersmith4615 not yet. Why? Are there some inherent problems I am not aware of? O have been comparing different high voltage supply designs for charging capacitors and it led me here. I built the power supply but not the whole powder coat gun.
I was hoping that you were excited by how well it performs. I am still surprised by the results I get. Pretty amazing for such a cheap, basic setup.
Have you checked my channel for other videos. A created a 2nd generation gun to help the powder flow more consistently from the nozzle.
Thank you, id like to make this a long time ago and now i know how! Very gratefull
You're welcome
Have you seen my 2nd generation gun? It is much better. th-cam.com/video/jJ77ekVlhQo/w-d-xo.html
I Will see, and learn more! I will certainly one for me! I very happy!
A great video, thank you. I am looking at whether I can do the same but without a compressor
Thanks. Some have been looking at using a 12v air mattress inflator. I really like that idea because you could create a complete handheld unit.
@@tinkersmith4615 I can't claim the idea as something similar was sold in the past but no longer made under the name "Craftsman Powder Coating System"
nice work, i have done something similar. but still trying to make the gun work
Particularly awesome video. Thanks for showing us. I'm thinking of making one. Initially thought of using old tv parts, never thought of using a taser.
Glad it was helpful!
Thank you T.S. great video.. one question , im wanting to powder coat inside a 1200mm tube of 45mm dia .. do you think this would work if i lengthened the barrel and had the venturi near the end of it ?
Cheers Barry
Thanks. Glad you enjoyed it.
I reckon it would work. Connect the tube to the negative wire and then blow the powder through with centre of tube with the gun. The powder should pass through and then cling outwards as it reaches exposed metal.
@@tinkersmith4615 thanks once again I'll give it a whirl
Very productif video. Good continuation. Algeria
Good and detailed explanation. Why is the positive high voltage attached to the pipe and the negative to the part? Can it be reversed?
I have tested it and it doesn't really matter which way it is around. I have done both and both work. I don't really know how to measure which is better.
@@tinkersmith4615 You are very useful man! I am asking because read both for tribo and corona powder coating. I wanted to make tribo gun as it is without high voltage. And they use teflon/PTFE/ which polarized the output tube negative. It may be useful.
There are two different types of powder coating guns. The most common are "corona" style (no... not wuhan) which uses a negative charge on the gun. Their main benefit is they last longer due to the parts not coming into contact with the powder, which is abrasive. The downside is they can have a problem with the faraday cage effect which prevents getting good coverage on the parts you're spraying.
The second type of gun is a "Tribo" style. These are gun positive and have an electrode that comes in contact with the powder, giving it a positive charge. These guns deposit much more material on the surface of what you're powder coating as well as into recessed areas. The downside to Tribo guns is they apply powder slower due to the lower PSI air use in order to charge the powder while going through the gun.
Based on the test video Tinker Smith has made, he seems to have good results with how much powder is deposited.
hi, how do you check if its positive or negative? if you touch with the positive a metall mass it do something? (i need to charge positively one powder for a project, but it must be positive charge)
I couldn't say for certain. I'm only guessing that it is follows straight through from input wire to output wire.
Hey thanks for the amazing video. There is someting bothering me tho, any powder coating system i have ever seen (that has a small power supply like the one you made) usually uses 15kv-25kv output and yours has "400kv" but it does not (or does it?) apply powder any thicker? I just wanted to know if you have any ideas about the reason behind it. Thanks again!
Good question, I don't really know. This is the only powder coating gun I have ever used. I built it because I wanted to get into powder coating and thought of the idea. I don't really know what high voltage I am running because I don't have the instruments to measure it. I am somewhat doubtful of the 400kV claim and assume that it would only produced that when 7v is applied. I am only running 4V and 2.5A so I don't know how that affects things without measuring it. Maybe it is running 100kV? Your guess is as good as mine. Thickness, not sure again. Did you want it thicker or thinner? I could run a few experiments for you at lower voltages? I first experimented with plain flour before I bought my first powder. Just wanted to see if the static charge would hold anything. Amazingly, it did! That was a very thick coating. Keen to hear your thought.
@@tinkersmith4615 Yeah, I also thought ebay listing is not %100 true. And even if it is true you probably have to run it at 6v. I would love to see you do some experiments using different voltages. I don't really know if i want it thicker or thinner, never done any powder coating before but I am just restoring a car and I was thinking of powder coating some parts. I already ordered parts for building the powder coating gun. I will also try to flour coat some parts haha. I guess you can use literally any type of powder to coat? I doubt it will be useful for anything tho. Thanks for fast reply.
Those cheap voltage boosters when run at 4v and 2.5a or so only put out about 30kv.
@@tinkersmith4615 flour, perfect ! brilliant too ! I'm going to build a few before I go buy an eastwood. eastwoods look pretty much same as what you built.
@@LBCAndrew cool, that is plenty :)
Thank you sir..... You saved me a lot of money...... 🤑
You're welcome :)
Brilliant video. I noticed the boost module warns to use power for less than 1 minute. Has this been a problem?
No because I use the current limiter.
I ran a duty cycle test to prove it: th-cam.com/video/m9PIINLQBW0/w-d-xo.html
Thank you for the particular long and interesting video 😉
Can we find that high voltage part in an old electric machine?
From Morocco 🇲🇦 thank you 🙏🏻 again.
salam khoya ?.
i am also from morocco.
did you manage to make it yet ?
Awesome Video TS
I've already started to order parts!
Could you post a link to the cheap gun and the bottle you used.
Thanks heaps!!
I already had a cheap air gun handle which is the one in the video. It is exactly the same as the Ozito Air Glow Gun from Bunnings (Australia): www.bunnings.com.au/ozito-air-blow-gun-kit_p5810654. I bought one for another device and tested it so I can confirm it is the same.
The bottle is nothing special either. The bottle in the video is a reused Northbrook Lightly Sparkling Spring Water bottle (500ml). Any tapered neck bottle will do.
Hope you enjoy your powder coating gun! Would love to hear your experiences with it.
sorry I want to ask the function of the 2 clamps in the generator where it is attached to it ... thank you
No problem at all. I should have been more specific. If you go to 1:50 in the video and pause you will see both alligator clips in the shot (the part where I am showing the gun in action). You will notice that the yellow wire (high voltage positive) clips to the top of the gun where the rod ops out of the barrel. This ensures that when the powder moves through the barrel it is robbed of negative ions. The blue wire (high voltage negative) is attached to the thick wire holding the item I am coating. This then grounds the work piece due to the high voltage passing down through the holding wire. As the charged powder moves towards the work piece it clings to it due to static electricity. Hope this helps.
Hello! I want to build a powder coating system like yours but i understand nothing about electricity and electric circuits. Do you have a book to recommend? Or some topics so i can search for on youtube? I really wish to have this knowledge. Anyway, thanks for the information in this video!
You shouldn't need electronics knowledge to build this DIY guy. I provided detailed instructions in this video and tried to pitch it to those very little or no electronics knowledge.
10/10 Tinker!
Thanks. I hope you enjoy using it.
Great video! I’m going to try and make it this weekend. I have o let one question for you. Does the powder from the bottle flow up through the vinyl tube or does it go around the tube and through the pvc? The way I understand it is the air blows though the vinyl and the powder is blown via the pvc tube? Thanks again !
Somebody else asked me the same question. I made this video to explain: th-cam.com/video/YsN4F2naDf0/w-d-xo.html
I also made a better version. The flow of powder is so much better. th-cam.com/video/jJ77ekVlhQo/w-d-xo.html
great tutorial which has inspired me to make one however i dont have a bench power supply, do you need one of these because it would not be cost effective for me to buy one just for this project as they are not cheap. i could buy a proper gun for not a lot more money. thanks regards Gary.
No, you don't need a bench power supply. I only used it to demonstrate a feature of the dc-dc module. A simply wall adapted from an old wifi modem will do. Have a look from 13:20 and you will see I talk about it in detail. Hope this helps.
You could probably even use a little 9v battery if you wanted to.
Looking into it further, I don't think a small 9v battery will be able to handle the max current draw of 2A. You may need to use another battery with a high amp draw if you wanted to use a battery.
@@tinkersmith4615 cheers mate, i will give it a go.
Why my multimeter doesn’t give me any measurements when I tried to set up the current power. The multimeter is properly settled up to read amps?
Usually there are 3 lead plugs on a multimeter: centre is ground (black lead), right reads volts and milliamps, left read amps. Did you move your red lead to the left hand plug when taking the reading?
i am assuming if you put some sort of masked design on the metal piece being painted, that it would prevent the paint from adhering to the metal in those spots? Like if you had the letter "A" masked onto the metal, would you have any paint get on the masked off "A"?
Yes. You would then need to leave the mask on while you place it in the oven for 10mins at 200deg. Once cooled you can then pull it off.
I have done it section off segments like the threads of a bolt but not a more complex shape like a letter.
thanks
You're welcome!
Hello again
What i mised in the video is what kind of opening there is in the bottlecap where the powder must go thru. Did you drill a hole thru the cap or is the cap totale open?
It seems I forgot to talk about that. As luck would have it, the external diameter of the 15mm PVC pipe slides nicely into the opening of most bottles. I kept the bottle cap because I wanted a bump stop to help set the depth of the air pipe off the bottom of the bottle (3mm or so). I just drilled a hole in the bottle cap, slid it up to the mark I wanted and then hot glued it in place.
@@tinkersmith4615 Thx for the reaction but i stil do not understand it.
The air is going thru the air pipe,then travels thru the powder en must then go back thru the bottlecap thru another hole right?
i made a video and out it on youtube to explain my question.
th-cam.com/video/WwB7MXJ3fd4/w-d-xo.html
Hope this answers your question: th-cam.com/video/YsN4F2naDf0/w-d-xo.html
I've been messing with this project. I found the boost converter ~3-6vdc input, 400kv output on Amazon. The reason the output wires are the same color is because the output is 400kVAC. I see from your follow on videos that the gun does work and the powder sticks to the work piece. Why does this even work with AC?
Great vid. Almost nothing to find on YT about making powdercoating guns. Could you make a vid, actualy using the gun ? Thanks already !
never mind, you did in the beginning. I was anctious to see the build and skiped the beginning. Great job man !!
Thanks mate! Really appreciate the feedback. I agree, there is a gap in DIY powder coating guns how-tos, that is one of the reasons why I created the video.
I enjoyed the video and am currently making this setup. Only problem that I see, as someone mentioned previously, is which leads go to the part and which goes to the gun. I thought powder coating like metal plating has to have the part on the negative lead as electricity flows positive to negative or does it not matter in this case? Aside from not knowing this one aspect, Great Video!
I have found that works with either lead attached to the work piece. I 'feel' it works best with the blue lead attached to the work piece but have no way of even testing if this is true.
@@tinkersmith4615 Now, I am confused. According to your video, you have the colored leads going to the output of the circuit board and the two brown leads are the output to the gun and the part being painted.
Your part looks to have a green and red lead no blue. The blue and yellow leads are your add-ons. You have a blue lead and a yellow but both are connected to the brown leads of the 400kv generator. Which brown lead is positive and which is negative or did you just try it and reverse it to get it right. Thanks
@@davidblahauvietz6863 I assume it. I assume that the red wire follows straight through to become the yellow on the other side (positive) and the green follows straight through to become the blue wire (negative). The blue I connect to the work piece and the yellow wire to the gun.
@@tinkersmith4615 Sounds good, thank You.
Hi, why does it have to be a bronze wire? Can it be a copper wire instead?
Thanks a lot for sharing, I’ll build it soon .
It is only bronze wire because that is what I already had. :-) The rod holding the tube in the bottle is aluminum. I can't see why copper wouldn't work. The only problem you might have is patina on the copper which might eventually alter its performance. Keep it clean and I reckon it should work just fine.
@@tinkersmith4615 Thanks!
I only have adapter with 2a output. Will it work like yours?
I was originally running it at 4V/2A. It worked but had more overspray. It might just take you a little longer to powder coat something. I found that 1.5A was too low. Why not start with the 2A adapter and if you come across another one, go with that. Would be keen to hear how you went.
Hi Tinker, just wondering if I were to make one of these guns, what power does my bench power supply need to be. Would something like a 15V, 2A DC Adjustable Regulated Linear Bench Power Supply be ok? If not could you point me in the right direction?
15v/2a would be ok as long as you only run the high voltage module at 4v/2a. The module itself will only draw roughly 3.33v/2a due to its internal resistance if a 2a limit is set. I am just in the final stages of putting together another video where I demonstrate this relationship. I will also show the performance of the gun when it is set at 2a. I will try to have it up as soon as I can.
@@tinkersmith4615 Thank you for your reply, really appreciated
@@tinkersmith4615 Actually since it steps the voltage down you need less input current than output current.
Basically the energy needs to be conserved, but then there are conversion losses often better than 80% but to play it safe and call it an easy to use for calculations 50%.
4vx2.5A = 10W, assuming the horrendous 50% efficiency -> 20W input power would be required or 20W/15V ~= 1.3A
What sort of wires are you using?
While a nice design and construction, I honestly believe you have way too much high voltage at the ends. I would try to reduce that substantiality. All you really need is a static charge to allow the power dust to stick to the part you are spraying, not serious arching. But other than that, clever setup...
I'm glad I found this video. I wasn't crazy about blowing mega$$$ on a kit just for a couple of occasional pieces at home. What air P.S.I. are you running on this? Thanks!
I hope you enjoy it. It only needs 5-10psi. Have you seen my other few videos?

Thanks for that. I had gone on to watching your other videos after I left the initial question. I've already ordered parts to make this!
At what airpressure do you use the gun ?
I was only running it at 5psi in the video. I have seen people run their commercial guns at 10psi or so but there always seemed to be a big cloud of overspray. At 5psi just enough is coming out that it is highly charged and so I get very little overspray. The neat thing is, if the work piece is round or thin the charged powder swings back and sticks to the back of it. Having said all that, if you run it at a higher psi the charge is plenty strong enough for the powder to hang on as the air passes over it.
I literally have all the pieces in my hand all i need is to put them together and buy some powder.

How to recognize which cable produces high voltages?
which one is + and which one is -?
I think might actually be AC. I simply followed the +ve and -ve through in a straight line and assumed that the other ends were the same.
I got a very stupid question where is the second high voltage cable mounted ? I mean one goes to the wire in the gun .... and the second ? Or could you use both in the gun with enough distance
The positive high voltage wire (yellow) clips onto the rod in the chamber at the front of the gun. The second high voltage wire (blue) clips onto the work piece itself. I usually clip it to the wire from which part I am powder coating is hanging from. At 1:38 in the video you can see it clipped to the hook at the top. This grounds the part and ensures the powder will cling to the work piece. Please come back to me if this doesn't answer your question.
@@tinkersmith4615 Okay i understand. i thought it would be enought if you put the ground from the "low current cabel"/power suply to the workpeace! So everything is clear
great video. how many minutes can it work? Have you ever tried
Thanks for the great question! You inspired me to run an experiment to find out. Let me know what you think: th-cam.com/video/m9PIINLQBW0/w-d-xo.html

thank you for your interest
thank you for all the information You are cool..
I have ordered all the bits n Bobs to. Make This and can't wait...
The only Thing I seem to be missing on the wiring side..
Is where do the 2 high voltage wires connect to That come out of the 400kv thingmebob.
Which one goes to the gun and which one goes to the part?
A mini wiring diagram would be bloody awesome mate. I will make u a video when I have made mine. Thank you 👌👍
Jimmy, did you figure out which lead from the high voltage generator goes to the part and which goes to the gun?
Thanks
David
@@davidblahauvietz6863 live + positive to the gun
@@Jimmy-choo Yes, but since both output wires on brown, which one is positive and which one is negative? The input wires are green and red. Red went to positive and green to negative according to Tinker's video, but the output wire are same color brown. I don't dare put my voltmeter on this as I don't think it will handle the 400k voltage.
@@davidblahauvietz6863 when holding the cylinder imagine the wires inside.. Left red... Right green... It works the same the other end.. Hope that helps

tryed everything powder will not stick help
Harbor Freight sells one for $80. Don't know if it is any good though. Reviews say it works, but it will work the third time? That's the major problem with el-cheapo stuff, it doesn't last.
The HF gun is 11kv, its really weak the powder doest attract to well to the piece, you want 15-25KV to get enough attraction on a coated piece for a second coat or a clear coat.
I'm a little late to the party here, but I do see one little issue that might change the efficiency of the system. Those little taser modules typically put out high frequency high voltage AC. For that to really be effective in a charged application system, it needs to be DC. You'd be better off using one of the lower-power 20kv modules and adding a couple of voltage multiplier circuit to the output. Use a couple of capacitors and diodes potted in wax or epoxy. Or even a just string of 1N4007 diodes potted in wax or epoxy attached to the output would probably do it.
Never too late. :) So build a bridge rectifier and use a 20kv module (to reduce the number of diodes required)? For example you would need 24x R3000 to rectify 20kV, where you would need 66 for 55kV?
I do like the idea. I might need to do some testing. The only hurdle I see is that current configuration produces really good results for very little time and money. Diodes, resin and all that is whole lot of manufacturing. Do you have a sense or gut feel for what the additional benefit would be the effort?
Actually I do know that if you supply 1A into these "400kV" modules you get about 30kV output. Ran a series of tests and measured the gap between the sparks. 30kV per cm.
Well I want to tell me more details about these 3 components like brand, model and some basic parameters because i didn't find them on your links and i want to search them on internet. Thanks
Try searching eBay for:
- high voltage generator 400kv
- dc converter constant current
For the second, look for one with 2 variable resistors to set the voltage and current.
@@tinkersmith4615 ...and the Air Glow Gun?
@@nelunicoara4483 Sorry, not sure what you mean. Do you mean, how to make the gun itself?
@@tinkersmith4615 You didn't tell me some detail aout it. I didn't find that one either. About building myself it's another storry.
Since the step down buck converter is capable of suppling 5A, would it be beneficial to have it run 2 3v - 6v 400kV Step up modules?
I have thought about it but haven't tested it. Running two modules in series would increase/double the voltage, say 100kV to 200kV. Running them in parallel would increase the current. My guess is that running them in parallel would achieve better results; i.e. less overspray and thicker coverage. I haven't tried it as I am content with the results I am getting.
Have you had any trouble with getting shocked because of using connection wires that is only rated for 600v. I have ordered 30kV wiring used with high voltage CO2 lasers.
I used very think wire for the high voltage wire in the video. I haven't been got however I have seen sparks jump on the negative side down to my saw horse legs if they touch. In my next model I used thicker gauge wire and have seen no spark jumps.
Btw, I have tested running the high voltage modules in parallel at 4V/1A for each; 4V/2A supply. Sadly, the powder won't stick at that current rating. I am currently working on a new video demonstrating all the different current settings, what works and what doesn't. Keep a look out.
@@tinkersmith4615 Thanks for your replies! I will be watching for the next video. I will also send you updates when I have finished my completed project.
This lifting module is from a stun gun, how does it say that it is rectified? there is no positive or negative
I'm not sure. I think it is a DC pulse module. I bought some high voltage diodes to make a bridge rectifier but haven't got around to it yet. It works really well without. I just used it again today. Works great.
what size copper is in the chamber nice video
Not sure. Will have to measure it and get back to you.
Have you seen this video by any chance: th-cam.com/video/7g_oLDS0Km8/w-d-xo.html
Next idea: using an old electric airbed pump and a couple of balloons to avoid having to buy a compressor.
Good idea! You could make it one compact unit.
You are particularly particular. LOL. Great video. Thank you.
Ah, you noticed my nervous tick. :) It is different each time.
Hello thanks for the great video. I built the gun but the problem I'm having it that powder doesn't really sticks to the metal. Can you please help?
That's strange. Are you getting a high voltage arc between the +ve and -ve wires? Some people find that their high voltage module is faulty.
@@tinkersmith4615 yes sir i am getting high voltage spark
Are you attaching the negative wire to the work piece? And is it metal?
Yes sjr
Sir*
Would fish tank compresor be sufficient enough for it 1,8l/min?
I couldn't say for sure but I doubt it would the airflow required. I am intrigued by the concept though. A compressor-less powder coating gun. It would be a super cheap set up and you probably would have less issues with moisture (no compression and expansion of gas). What about using an air mattress inflator pump?
Something like this: www.bunnings.com.au/ozito-500l-min-electric-air-pump_p0242858?gclid=Cj0KCQiA6t6ABhDMARIsAONIYyynjBaXJ-TlSu7800huyx2i9LO8TM80saDZWGsQACyTPN-rSQZoeCIaAvAlEALw_wcB&gclsrc=aw.ds
I think its a nice idea also a was thinking about 12 car compresor it can be hooked up to same power supply as gun
Great video! I'm trying to figure out how to make a battery operated electrostatic circuit for a regular spray paint can for an art project. I'm happy to pay for your time if that's something you can show me how to make. Thanks.
Have you seen this video?: th-cam.com/video/THmUjPR7p1E/w-d-xo.html
You could possibly achieve this by placing 4 prongs just around the nose of the spray gun, close to but out of the fan, and then connect those to the positive high voltage wire of my electrical unit this video. The negative you could either connect to work piece you are spraying (if it is metal) or to a tent peg in the ground.
Is this dangerous as it is high voltage as i want to build one but just worried about that zapper thing thanks
The amp are extremely low and it is amps that will damage body tissue. I have been zapped a number of times and found that it tickles more of than anything.
That’s good to know thanks
@@tinkersmith4615 It might be true, but you only need a few milliamps to stop your heart. Also, it's a bit terrifying if the circuitry malfunctions, which which can change the electrical parameters.
sorry can you show me the schematic of the control circuit
Do you mean how I wired the two components together or the schematics of the buck converter and high voltage modules themselves?
I'm manufacturing AC outdoor unit stands in India. Its a startup actually! Out sourcing my job for an industrial powder coating service costs me more than my actual price. After seeing this video, I have ordered parts that you recommended on Amazon. Can you suggest a way to increase the spraying speed, to increase my production?... Thanks in advance brother!👍
The speed I coat at was based on wanting the least amount of overspray. I have seen video of production units where they have an extractor fan and filter to capture the overspray and they create huge clouds of powder. I have never tried this with my gun (greater volume of air so large clouds of powder) so I don't know at what rate it could go.
I'll have a bit more of a think.
Have you seen my Generation 2 gun?: th-cam.com/video/jJ77ekVlhQo/w-d-xo.html. Today I used this gun at 20psi @ 4v/2.5a and it went on super fast. There was more overspray but if time is of the essence then this would be a great method.
@@tinkersmith4615 Thanks for your reply. Please do try this and give us a good review about it. Does increasing the current / increasing the KV improve the coating speed?
But what about this particular gun in this particular video?
Why not use a cell phone charger also known as a USB power supply which puts out 5V and 500 -2000 mAH to power your high voltage module?
I guess you could. Haven't tried it. Two things to remember though: 1) You would need to ensure that amps are not exceeded when the wires short, and 2) running at 5v will add my power to the module which may require a reduction in the amperage setting.
Bro seems to really like the word petcular
You are not the first to notice 😄
Is there any video on you actually using this contraption?
There is a short clip from 1:20.
