I really enjoyed watching your video very informative, I’m building a wet sand blasting cabinet and was disappointed by the results, I think some of the knowledge share here might help me going on the right track !
The challenging part is keeping it all in a slurry so the suction gun can pull it up. Then making sure you have the right suction. Your compressors CFM capabilities plays a big role in that. This is for dry blasting, but it gives you an idea of what is needed: th-cam.com/video/OaWxDhMGiIk/w-d-xo.html
I’m new to working on Blass cabinets. I use one at a local CNC machine shop and I’m probably the only guy that ever uses it. Getting ready to add glass beads to the cabinet and was wondering if the entire 50 pound bag was necessary to put in?
For suction cabinets the answer is always no. This is a good guide for that: th-cam.com/video/zTm1bg5uTPQ/w-d-xo.html For pressure cabinets you would want to put in enough to almost fill the entire pressure pot. This can very greatly as pressure pots come a wide range of sizes sizes.
thank you for great video, can you please explain the higher the gauge reads the low the vacuum so moving the nozzle out dropping the reading means more vacuum, thank you
I'll try to give you an explanation. A proper vacuum gauge will read from 0"-29" HG. So the higher the indicated value, the better or more vacuum. We usually see our suction guns read from 15"-16" HG once they have been adjusted. As the orifice is extended out of the gun the vacuum will increase to a certain point and past the point it begin to decrease (kind of like a sweet spot). Using this type of setup for the gun is the best way to know if your gun is drawing the most amount of vacuum and is working correctly. Thanks for the question and I hope this helps. - Tracy
The principals of suction will still work outside the cabinet. Provided you have the correct compressor for the nozzle and jet pairing. Moisture is your enemy. Try to keep the media dry.
Yes we do. You can find a video on those here: th-cam.com/video/yNiTg98F6TE/w-d-xo.html They can be purchased from our store: blast-it-all.com/product-category/eco-gun-parts/
Great video. Thank you. I was having problem with suction of my blasting gun. I will check adjusting the orifice with vacuum gauge. Is it possible for the gun body to wear out?
I get 18 inches of vacuum and my gun shoots like crap, we have two guns in our cabinet and one shoots fine at 15-16 but the other with a higher vacuum does not. Maybe i'm dumb but it makes no sense.
The nozzles are matched with the orifice to provide the best possible suction. Here is a chart that shows nozzle and orifice pairing. blast-it-all.com/cfm_requirements/
I have a sullair 160 air compressor has 4 cyclinder car engine it puts out 160 cfm at 105psi continuously its industrial what nozzle size do you recommend
What size compressor is needed to run your gun? If my compressor doesn't meet your recommendation should I stay with the gun that came with the cabinet? My cabinet is the big H F that is all over you tube and my compressor is an Ingersoll Rand Garage Mate.
Edward that particular Gun requires a minimum of 21 CFM at 60-80 PSI. Here is how an Ingersoll Rand rep explained it to WorkshopAddict.com. th-cam.com/video/6vWqa7WjkVU/w-d-xo.html
@@blastitall measured vacuum on inlet. Thought that range would be greater, but it didn't change a lot between almost fully threded in to say 6 or 7 threads out. Gauge read about 0,4bar vacuum +/- 0,2bar But still, was good to check that.
Thanks a lot

@@blastitall thanks ! I’ve a 7,5 hp with 25 CFM i’ll try to choose my jet accordingly, i use a water pump to also help getting the slurry up !
thank you for this video it was very informative
Stay tuned we have more to come.

@@blastitall that is a great help now i understand thank you for your help and quick reply regards john
@@blastitall thank you Tracy fine tuned my sandblast gun today and working fantastic regards john
kind of stupid question here... can you use this gun without owning a cabinet?
The principals of suction will still work outside the cabinet. Provided you have the correct compressor for the nozzle and jet pairing. Moisture is your enemy. Try to keep the media dry.
Do you have a trigger model? I really don’t like to stand on one foot while blasting!😊
Yes we do. You can find a video on those here: th-cam.com/video/yNiTg98F6TE/w-d-xo.html
They can be purchased from our store: blast-it-all.com/product-category/eco-gun-parts/
Great video. Thank you. I was having problem with suction of my blasting gun. I will check adjusting the orifice with vacuum gauge.
Is it possible for the gun body to wear out?
Yes, the gun body can wear out. We have seen some with holes in them.
Informative video, thanks

That does seem a little odd. When you say it shoots like crap what is it doing or not doing?
There are small nozzles? Or some part extra to make it compatible with small nozzles for the other type of gun
The nozzles are matched with the orifice to provide the best possible suction. Here is a chart that shows nozzle and orifice pairing. blast-it-all.com/cfm_requirements/
I have a sullair 160 air compressor has 4 cyclinder car engine it puts out 160 cfm at 105psi continuously its industrial what nozzle size do you recommend
The nozzle and jet size will be different depending on what type of work you are going to be doing. What will you be blasting?
@@johnklaver4960 I will be running coal slag on car frame its about .140 thick
What blast gun do you have?
Try a number 4 or 5 Nozzle

Thanks for informative video. Really liked about vacuum gauge attachted to gun to measure best adjusment. Will try that.
@@pizdriks Let us know how it goes.

@@pizdriks Make sure your nozzle is in good shape as well and is the correct size (Matches the Orifice size)
