Great idea, please do another follow up video and how did you go with different media, for a weekend warrior this saves a lot of money with the need for a big air compressor

I actually tried this concept last summer. I moved and did not have 220v to run my compressor in my garage. I used my gas pressure washer. It did not work as good as air since the gun was not optimized. I also hooked it up to a water source and it adds 1-2gpm to the system which is not ideal. My basin fills up fast, and water would have to be purged every few minutes. I wouldn't feel comfortable with filtering water from slurry source, especially when you end up running finer media. I plan to revisit the concept soon with a better gun design.

Hi there, it's nice to know you tried this out as well! The gun is different from a standard vapor blasting machine that uses air, and therefore it must be custom made to suit a pressure washer with the correct valve. The amount of pressurized water in this system does not change the cleaning effect, the abrasive material does. This system could be improved to accept different types of material with a "quick-change-system" and when using finer media, one must use a finer filter material. There are many synthetic filters out there that will work just fine, but I will make sure to follow-up on this topic. Thanks for watching and leaving an insightful comment! Regards Andreas

Looks very interesting! Please keep us updated with your project revisions. I'm sure there are tweaks to come. By the way, I was involved in using high pressure water and an injector to draw in media over 30 years ago. A PhD hydraulic engineer told me that the media being drawn into the water stream picks up 1/3 of the pressure. So, a 1500psi pressure washer will result in media hitting the object being cleaned at an effective 500psi. We were using 10,000psi at 8gpm but for the same horsepower, we could have done more at 15,000psi at 2gpm. In this type system, pressure is more important than flow.

would it be the same pressure drop seeing as he has a different pump feeding in the media? from your explanation it sounds more like a system that is drawing media into the high velocity stream and using that drop in pressure to pull the media in and accelerate it

I'm super curious about this project. I recently built the traditional style vapor blaster using compressed air. Using a pressure washer to propel the slurry is a great idea though. I'm curious if a pressure washer is a bit overkill being that you generally limit the air pressure to around 60psi on a traditional setup. I did some Google searching and it looks like you can buy water pumps in all sorts of pressure ratings including 60psi. I'll be on the lookout for an update when you try out a finer media!

At psi above 60 with just air you would be breaking glass beads and turning them into crushed glass. Water will have some cushioning effect, but 2400psi, which is about what the pressure washers run at is way too much. you need an additional reservoir that has low pressure water flowing in as well to reduce water psi and increase flow rate by like 20x to get to sub 100psi at the nozzle.

What a great idea. You could build a second tank that would filter the water and recycle it and not have to use fresh water.

Thanks a lot, Joe! I agree with you. Many filtering compartments on machines use a type of overflow system to capture their desired liquid (oil, coolant, water etc.) The main goal is two capture two different types of fluid: 1: Water & Media for blasting 2: Fresh water for the pressure side With this in mind, any type of system that can separate this will work just fine. I will try and share an update video on this topic sometime soon👍🏽 Regards Andreas

Glass beads preferably no 13 or 170 to 325 is what you want. However the pressure washer is to high of a pressure and will destroy the media as well if any media gets into the pump of the pressure washer it will be destroyed

Hello there! Thank you for your suggestion about the glass bead. I think that would give these parts an awesome finish and a neat shine to them! Using a smaller bead would mean I need to change out my filtration system for a finer material. I am planning on upgrading the filtration system so I have 3 levels of "security" before the water is clean enough for the pressure washer. I really wouldn't want the media to chew up the inside of my pressure washer haha.

Hi Joseph, thanks for viewing! I will share an update about this machine in the next couple of weeks.

Hey man you surely proved the concept! Only way I've ever seen to achieve "dustless" blasting. Definitely a great idea! Curious to see if you find that sweet media that works best. Always used silica myself but never wet like this. I think they use granite in water jets. I was pondering if this could be construed as a high volume low pressure water jet lol. Obviously would only cut paper. Lord knows I've spent lots of hours trying to improve the function of a blast cabinet, I think you've done an excellent job. Since the concept works, time to throw more power! Bigger pump on the media solution and higher pressure washer pump. Can't wait to see what you can figure out. Maybe some solvent or acid in the water? Keep in posting brother, we love it!

I'm really glad it worked out this way and now I'll try and optimize the system. That's right, it really is a dustless form of sandblasting/media-blasting. The media is a little bit too coarse for this aluminum, but I have a feeling a smaller grit will work much better! I'm not even sure how strong water jets are, but I know this pressure washer cannot reach such pressure! The one I used in this video has a max rating of 2000PSI. If I need to bring the pressure up a little bit, I can always make a smaller orifice, without damaging the pressure washer. You know exactly what it means to improve and optimize a blasting cabinet, especially since you've done it yourself! What media do you usually run and for what materials? Thank you for your kind words!! I'll do my best to make this system better and hopefully I can get a better camera setup. The blasting footage was very poor, because the water shot up against the glass. This is something I'd like to improve, to make better timelapses of the parts I clean.

its hard to compare to those air power vapor blaster. it looked pretty similar to the air powered unit but how could we know if this is equivalent to 12 cfm at 60 psi or 5 cfm at 100 psi is hard to say. you would probably need to inspect the glass beads after using them. if the manufacturer says use the glass beads under 60 psi or they will break, if they you don't break then you know you are under the equivalent of 60 psi. but realistically, as long as you get the finish that you are looking for, who cares how it compares. earlier I was thinking why not with a power washer that is what they use for outside application pressure washer with an attachment at the tip. Then start looking then bam, I found your video!!! glad to see I'm not the only crazy one to have had that taught

I would say they are very comparable, when it comes down to the function of the machine. I could install pressure gauge to see what values I have, but I know that this systems already works the way it should, so I don‘t need to. The glass bead will always break down over time, but I‘m not sure at what rate. If I could regulate my pressure, I could probably reuse the same media for a very long time! I noticed the pressure isn‘t as important as some „experts“ say it is, but the media is! In this video I chose crushed glass for my application, but I‘m going to try glass bead and see what results I can achieve. Updates will follow and thank you for your great comment.

I technically do have a "nozzle"in this setup, but it cannot been seen. At 04:25 I mention I have a built-in orifice right after the valve. Usually on a pressure washers, you get different nozzle tips or even one that you can turn in a circle, to choose your desired output. The smallest hole (nozzle setting) for this pressure washer, was a 1.5mm hole. I didn't have a 1.5mm drill bit, so I had to drill a little bit bigger. If the orifice would be smaller, I would increase the pressure and the pressure relief valves within the pressure washer would still be able to handle it. It would be great to be able to read the output pressure and to adjust the settings. I'll have to figure out how I can integrate that into this setup. It probably would increase the cleaning action and that's something I'll take into consideration. Thanks for your comment, CJ!

I did a double take on this video. This has potential. Not everybody can afford a compressor and electric pressure washers are cheap. Your media is too abrasive. It’s damaging the aluminum. But lets see what it does with the glass bead.

Hi Randy! Thank you so much for watching this video and leaving a comment. I agree, air compressors can get pricey, pretty quickly and that‘s exactly why I tried to go this route😁 I am aware that this 30-60 crushed glass abrasive is very rough and I might only use it for the BMW rebuild project. I‘ve seen many oxidized and discolored cast aluminum parts before, but this metal is in very rough shape. The oxidation layer is very thick and I was trying to approach this as a „roughing“ stage. I have since collected some information about aluminum preservation and I will explain why I‘m opting for a rougher grit abrasive on the BMW cast aluminum parts. I will make a follow up video with slight modifications I made to this Blast-cabinet and also shed more details on the machine. Thank again! Regards Andreas

Hi Jonny! I‘m glad you found my video and hopefully it gave you a little insight on how you could build one yourself😃 The nozzle consists of two parts: pressure washer feed and the front portion is dedicated to the media feed. Most pressure washers have high pressure ratings and therefore you‘ll have a strong valve. I actually used the exact same valve from a pressure washer handle. This was integrated into the back of an existing „sandblasting-gun“ and I just merged the two parts together. Pretty simple actually and it turned out to be very compact! I hope this helps.
