Edit: I should have read other comments before typing all this out ha! Got a suggestion that might help as your media is coming in bursts. A vacuum is being created yes, but not enough to pull through a trickle of media so it builds up and sucks a load of media all at once. If you gravity feed your abrasive line from the bottom of a modded bucket it's much more consistent. You'll have to play around with the ID of the abrasive hose otherwise you'll pull too much media through.. or try a valve. When you pull too much media through, like when it bursts through on yours, the particles collide with themselves and reduce their own kinetic energy so you get less effective rust removal, plus it wastes media which unless you're recovering and drying out is costly.
Brad, great video. I was thinking that a gravity feed to the hose from the bucket would improve abrasive flow. It would require fabrication of a stand, modifications to the bottom of the plastic bucket for an output port/hose connection offset to one side and the bucket would have to sit on an angle to keep an output port covered with abrasive. Great idea using a vacuum gauge.
Thanks Paul. I was giving some thought to an idea like that a while back, but for my siphon blaster to reduce intermittent abrasive flow. Any advantage to help abrasive flow is a good one.
Nice. Do the same with my pressure washer and have combined with a slurry pump to drive the sand through. It can be a very slow process so I only use it for hard to get at sections preferring to strip the rest with a wire wheel.
This is a good video, thank you for your time and effort to share your build with us. You mentioned that you have the nozzles custom made, just curious how much it cost to have one made because I had some ideas I would like to talk to you about if you have some time to communicate by email or phone. Thank you.
The problem with pressure washer blasting is the media is difficult to reclaim. Air/vapour blasting will recycle the media if used in a cabinet but requires a large compressor to function. I would like to see if an all water blast cabinet would work, with a slurry/capture tank instead of dry media, a fan spray pattern would also probably be beneficial. With the slurry agitation and pressure for blasting coming from the same source the setup cost would be reduced significantly (no need for an air compressor or slurry pump), it would need an overflow from the slurry tank with a screen so that only water can escape the slurry tank or a trap to allow the media to settle out of the overflow water. You could possibly recapture the water in a second filtered tank to feed the blaster (not essential but would be great if the system could be self contained)
Hi Nexus. I have a recapture closed loop system as you described which I use in my business. I had a lot of people inquire about this over the years, so I wrote plans which I finished this winter on how to build such a system that I am selling now. Regarding fan spray, I am working on a spray pattern setup. I have the nozzle itself, but need to match the jet. Without it, you just get a fat elliptical pattern.
Just an idea to get more even feed in the bucket put a cone shape say for example a traffic cone into the bucket and maybe rise the bucket up higher you just might get a better grit flow. Just a thought. Good luck 👍
The problem with any pressure washer based blaster is two fold: 1. Most pressure washers are lower power than decent air compressor 2. water is heavy and it does not accelerate to nearly the same velocity as air, hence it cannot accelerate the abrasives to the same velocities as air can.
Sort of a long story. I have film of building it, but my truck got totaled before I could take it back to the farm and record better test footage. I do have some ok clips, but I wanted better. Maybe I can use what I have. I have a lot of video that needs edited.
@@ArnoldsDesign Would be great to see whatever you have. I modified my old Woods 5ft brush hog years ago. Cut out a section of the rear so the blades throw the grass out the back. Cuts more freely. Needs less power to run it.
Could this be used with The king's power washer gun? It does up to 20 gpm and operates around 2500 - 4000 psi? If so what would be the cost ? This innovation is very interesting. Thanks in advance.
Incredibly inspirational work man. I know you might have covered it before somewhere but i'm interested in what type of material you use in the vapor blaster for a fine and shiny or polished finish you get in some of these videos. Also, did you say somewhere that you would sell these vapor honing guns you machine? I loved the red one. Keep'em coming.
Thanks Rick. I use glass bead for the final finish. I don't make the red gun for sale. It's too involved to produce, but I am redesigning for one for the same output. I sell the silver guns right now though. They can be used in wet and dry blasters.
Hey, you made a water jet cutter that works on glass! Evidently this is the Holy Grail of CNC. Did you try messing with the internal jet size on the water feed?
Cool. How is it the holy grail of cnc? Yes, I did experiment with different jet sizes, but had to be careful not to overload the pump. Probably if I wanted to use this for cutting alone, I'd have to make the jet with a longer internal hole, to try to get a laminar flow. I don't know though. This is my first attempt at it.
@@shirothehero0609 Cool. Share the video with the water jet guys. Maybe they'll take this and run with it... and buy my blasting gun too at the same time.
Well done for making the video...........but!!! Show us how you made it and what it does............... you talking to your hand doesn't make great entertainment .......... it's abrasive!!! Stephan
I have a previous video where I show it being machined. I don't show the adapter design because it's proprietary, though I'm sure someone can figure it out if I could.
