Making My Homemade Powder Coating Gun V.4

- Another contraption I put together mostly from recycle materials. I made this homemade powder coating gun to have a push button switch trigger tied to a solenoid valve that controls the air flow. This is in-line with my future plan to incorporate a powder pump to feed the gun through a hose from a separate powder hopper. Below links for related videos:

This is another level of brilliance!!!
You are very creative. I enjoyed watching how you progressed with the build, and most components from scrap or inexpensive parts. I almost went and built a gun like yours. In the end I decided to buy a WX-958 machine. I just wanted to mention, that your gun doesn't have a resistor in series with the electrode. The WX-958 machine has nozzles with 4 x 1Mohm 1W resistors, inside the electrode tube. They prevent arching by limiting the current. Also the handle of the gun mus have a metal section so that you are grounded. Just a thought, it might be safer for you.
Hi. Thanks for the comment. My previous gun version is made of metal that I connected to ground. I will definitely put a metal section on the handle for grounding. I tried connecting resistors at the electrode, but spark jumps between the leads. I will have to enclose that in epoxy. I will be publishing one more video of my recent contraption which I think is the best design for a homemade gun.
@@DIYPhil, I looked again and the resistors are 4x3Mohm resistors in the short fan nozzle, and 5x3Mohm in the long nozzle. So it's total 12 to 15 Mohm. I have notised in the OEM Gema gun cascade, the resistors are built in, inside the resin.
@@trp051 Thanks a lot. Very good information. In my latest cascade, I filled them with resin but did not include the resistors because I am not sure of the values. Without a resistor my gun over charge the powder that is why I am getting orange peel and back ionization. I can only get 1 Mohm resistor so far but will keep an eye for at least 3 Mohm values.
I have been watching your videos. You have been doing an awesomejob. Have you attempted to two coats of powder ? Base color and a clear ontop? or a primer coat and base color? That would be cool to see how your DIY gun works with multiple coats.
Hi. I ever spray powder on painted metal parts for testing purposes and the powder stick to it, no problem. However, I did not actually cure the part in the oven. That is something I want to do on future videos. I already have a clear coat powder at hand.
Hello, is there any pdf or link where you have put together the entire circuit diagrams for a clearer understanding
Great job. Very creative.
Thanks. I had these clips several months ago. I only had time to edit the videos and upload it now.
Hola soy de Chile y me gustará saber si vende este equipo ya listo y enviarme Aquí 220v 50her
you removed the reference winding from the coil ? ( it would be nice to know the connection with the modified coil from your last video.as you not using the high voltage circuit. I wonder how to do it and revwre removing the thin wire from primary winding not to use the hole circuet where the parts are getting hot...
Hi. I removed the thin wire (feed back coil) from the primary spool because I'm not using it anymore with the 555 timer driver circuit. Only one transformer will work fine. I used 2 transformers in series-parallel configuration to get even higher output voltage. In the previous video I show the circuit diagram of how I connected the 2 transformers.
Have you ever looked up triboelectric based powder guns? No HV power supply required.
Yes. That is something at the back of my mind and I always want to attempt building in the future. At this point, I am making my project out of easy to get components and mostly recycled materials. With a tribo gun, I have to somehow get a suitable material and may need machining, which will involve additional cost. Not within my budget constraints at the moment.
I am following with much interest, just finishing my hv cascade now. I want to make the shell on 3D printer to share with others so that’s probably going to be my biggest hurdle. What resistor value are you going to add so it’s not too powerful?
Hi. Nice to hear from you. Some viewers sent me photos in email of their DIY powder coating gun inspired by my project and theirs looks very impressive and professional. I can imagine you can also make a good product with the 3D printer in your disposal. The photos I saw on the internet of HV cascade has what looks like 4 pieces of 10 Mohm resistors in series. I already tried puting resistor in the past, but spark just jumps across the resistor body and to the terminals. I will try to put the resistor in clear epoxy. Those in Mohm values.
@@DIYPhil thanks, I was looking at the hv cascades too and thought they were 4 x 1.5Mohm, I also just worked out they need to be glass glaze type to handle the hv. Any chance of please sharing what others have made?
@@DIYPhil I found some clearer photos and I think you are correct, the photos I found use 25Mohm but only 5ma diodes so need a lot more protection. Honestly if I hadn’t ordered the other parts beforehand it would have been much easier and almost as cheap to order of aliexpress pre-made.

Can you help me with building the power supply. Can you provide me with your email address? Please I would be grateful
You can send me an email at philipal2015@gmail.com. Did you watch my other videos about building the power supply yet?
