Thank you for this detailed, very interesting presentation. I think you have unique features to your case that do put you a psi/bar above the rest 😏 Thank you 👌
I am connecting two 6.5 hp compressors into one line that goes through a series of vertical pipe lines zig zagging. The line has a large air dryer at the end. What size orifice nozzle do you think I could have running the two 6.5 hp compressors together? Thank you
I have never combined compressors personally, but it can be done. If done properly it there should be very little loss of CFM. Your combination should yield around 40 CFM. Be careful. Also not sure what you're planning for, but a 6.5 HP compressor should produce around 22 CFM at 80 PSI, which would work well for a suction cabinet and 21 CFM air orifice. #4 gun on our website. This chart gives you CFM requirements for suction and pressure system. blast-it-all.com/cfm_requirements/
@@blastitall I plan to use the two compressors only if needed. I was going to use a 5/32 nozzle with a medium grit crushed glass. If I understand the use of the chart I should be good to go? Thank you for your help
This cabinet was designed to be used with lighter weight media (Aluminum Oxide, Glass Beads, Crushed Glass, etc). We also make cabinets designed for steel shot and cabinets designed for soda.
I am certain abrasive blasting could remove the coating on the other non stick pans, however the processes described online to re-coat them seem unsafe for cooking. However, reasoning cast iron cookware is as safe as it always has been.
We have a larger compressor, because we run the whole shop with it. The air jet and nozzle combo in the gun for this video requires 21 CFM at 80 PSI during blasting.
You are the GOAT man. I love all your videos, mostly because I've been blasting with "all the wrong stuff" for years lol. So I'm watching, learning, saving my money so I can get the right stuff, bigger Air Compressor and such. Thanks for knowledge and sharing it man. Truly
That was blasted using our ECO suction trigger gun. The Air Orifice on the gun in the video was 3/32 and the Nozzle was 1/4". I have done other videos with larger nozzles and air orifices. I usually use a number 4 gun. This sizing chart gives you the correct orifice and nozzle pairing: blast-it-all.com/cfm_requirements/
I just recently added a dust collector to my sandblast cabinet but I´ve been wondering how big should I drill an air inlet to my cabinet if my suction exhaust is 3" wide?
I got a 3.7 horsepower DeWalt 60 Gallon Compressor, 11.5CFM at 90PSI, and I'm just using the harbor freight gun because I cant afford one of y'all's units at this moment, should I be safe? (im going to be using high flow fittings and a short 3/4 airhose from the compressor to the Cabinet)
Thanks for the wealth of knowledge. A large compressor is simply not an option for me, I run a 5.5CFM compressor, which gun, orifice and jet would be best for me?
If you need a trigger operated gun our 12 CFM would be a good fit. blast-it-all.com/product/gun-eco-w-14-ceramic-nozzle/ If you use a foot pedal controlled gun then our 12 CFM would be a good fit. blast-it-all.com/product/3-gun-complete-w-ceramic-nozzle-1-4-diameter/ This CFM chart shows you how the nozzles and air jets are paired and the required CFM: blast-it-all.com/cfm_requirements/
If you stick to a suction gun that is 21 CFM or less. That would be our number 4 gun with a 1/8" air jet and 1/4" Nozzle. This chart shows how they are paired: blast-it-all.com/cfm_requirements/
Yes. Steel shot is much more dense than aluminum oxide which makes recovery more challenging. But the biggest issue is the explosive hazard that is created when blasting with the two.
@blastitall what do you mean by an explosive hazard? I've mixed them together unknowingly. I have a metering valve. The biggest issue it seems is my flow is not good and it's clogging.
@@BimmerFix The flow issue is most likely related to the density and weight. Steel Shot 300lbs per cubic foot Aluminum Oxide 240lbs per cubic foot When you say "mixing" if you mean using them at the same time, that is a bad idea. If by mixing you mean switching back and forth, you need to make sure everything is cleaned out when switching. This is from the SDS for steel shot Particles liable to produce a fire hazard are the following: •Metal dust. •Plastic dust. •Dust produced when blasting metals coated with paint, rubber, etc... The SDS can be found here: blast-it-all.com/wp-content/uploads/2024/05/SS-SDS.pdf
@blastitall thank you for your reply. In this case, any blasting is a fire hazard, it seems. I guess the mistake I made, I dumped 50lbs of AlOx and 50 lbs of steelshot together in the blast cabinet. Then I realized that's too much, so took most of it out. Still can't blast with good flow...BTW bag of 50lbs steelshot was 5 times smaller than 50lbs bag of AlOx. Should I just throw it out now? I figure there's no way to separate them now...
Yes and no to fire hazard. Aluminum oxide, glass bead, and crushed glass are not listed as fire or explosion hazards. However, organic media, steel shot, and some others are. As for the mixture. I don't think there is a good way to unmix that.
The CFM requirement is based on the nozzle size and the PSI setting. A 3/16" nozzle at 90 PSI would require 41 CFM. On the right hand side of the page below there is a CFM requirement chart for pressure which is what this machine it. blast-it-all.com/cfm_requirements/
Edit to my previous comment found one at 3.5hp with 5.7scfm for 100 bucks! thats twice the horsepower and a little more air circumference and its still an oilless compressor a decent find indeed alot better than anything im finding at harbor freight for 200 or marketplace etc for that matter they all seem to make 1.5 - 1.7hp with 4.0scfm so im buying it in the morning!
Blast and wait isn't necessarily a bad. It all depends on the project. One of the big issues is the incorrect labeling of blast guns and the CFM needed for blasting. This causes people to have to blast and wait when they were not anticipating it. This video explains one of the issues with a very common gun: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tfRZ-5cdlY4.html
@@ShockeyUSA the one in the video is a MCGRAW 21 Gallon, 175 PSI Oil-Free Vertical Air Compressor from Harbor Freight. It is my personal compressor. I purchased it about 4 years ago.
Say for instance im just blasting a few small parts on an old tiller as opposed to sanding and wire wheeling. I dont mind being patient that seems to be alot faster and alot less damaging to thin metal, especially since it cant "keep up" with gun provided. That being said then it is much less likely to damage a something as oppsed to wire wheel or flap disk. Belt sander is does bell but doesnt access the small crevices that id like to get to bare metal. From what i see in the video im more than happy with that because then you can go prime a piece while building pressure again. I know its against your judgement but im doing it anyways 😅😂😅
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.
P.O.S. 💩Mine died in less than 2 years time, with very little use. Mostly to air up tires, or occasionally run an air tool or two. Well of $250.00 wasted. Good luck with finding support or parts. Pretty much non-existent.
If by tire air compressor you mean one of the little tire inflators, no. Most of the manuals I have read for those indicate the produces less than 1 CFM. The smallest CFM air jet we use needs 12 CFM. It is possible to get a smaller compressor, 4CFM, with a tank and blast for short periods of time. But for larger projects something the produces a few more CFM than the gun requires is what would be recommended. This shows how that works: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TQoe0ov4M_c.html
I use an 18CFM gas engine compressor with a HF cabinet. I’ve also installed 1 inch tubing for siphoning/ metering. A couple days ago I was chugging along and blasted several parts, however I haven’t been able to find that sweet spot again. Now at most I get a small amount of media when I pulse the trigger. I can see media almost making its way to the top of the hose but it doesn’t have great suction after several hours of use. The HF gun is really bad too, the best performing ceramic nozzle was 1/8” and it wore out fast, I also had to keep the retaining nut loose and wiggle it around from time to time so a lot of media was falling out when the trigger was not pulled. If I’ve ensured there are no clogs and changed the media several times, would a gun like this give me more consistent performance? Also the metering valve doesn’t seem to have an effect on the suction.
There are a lot of factors in suction abrasive blasting performance. The gun paired with the proper nozzle and making sure the nozzle is not worn makes a big difference in the suction. This video briefly talks about nozzle pairing: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-syMz9l0VOTI.html This video goes more into the details of the suction gun: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-dKT9XeFhNNY.html
A truly great video. Thank you for making and sharing this. I have a highly modified blasting cabinet and wouldn't be without it. However, I am slightly disappointed that my new 14Cfm compressor with 200ltr tank, is running constantly and I find that it only get about 10 minutes of effective blasting then I have to wait while it's charging back up with air. I never thought about the orifice in the gun and needing to reduce it. I will have another watch of your video again and see if I can work out what size I should go for. I was actually thinking about buying a second compressor to add into my system before this video. Kind regards Paul from the UK
@@itsalldoable This chart shows you what are after. blast-it-all.com/cfm_requirements/ unfortunately we do not ship outside of the continental us, but you should be able to find the correct nozzle and jet. 3/32" air jet makes it 12 CFM at 80 PSI.
I HAVE A COMPRESSOR OF ONE THOUSAND TWO HUNDRED LITERS / MIN TO WHICH I TRY TO ADAPT A BLASTING GUN AND I DO NOT KNOW WHAT NOZZLE TO USE. WHAT CAN YOU RECOMMEND ME ? MAINTAINS AN EIGHT-POINT FIVE-BAR PRESSURE. PLEASE INFO !
@@claudiumalanga1933 Looks like you have Honda gas engine running that compressor. I looked for the specs on one of those and it looks like it is 6.2 HP continuous operation motor. ( Need the exact model to check) That should get you about 19.84 CFM. A 12 CFM would be a good fit for that. However the motor specs do say it can have a little more horse power going full speed. That should get you up to a 21 CFM, but it will idle high all the time.
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.
An adjustable forearm pad would be a nice accessory for someone that stands at it all day (like I did). Maybe gel around the openings. The trap door for fallen items is a nice feature. Double doors to prevent warping is a good idea.
We have an adjustable arm rest that can be added to our blast cabinets. You can see it in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-O_VqJ7AHZHk.html
is there a link for this specific one? I have a small compressor the lowes kobalt 26 gallon quitetech 4.5 CFM at 90 PSI with 150 max psi. Im using the harbor freight benchtop with metering valve but still not the best results. Can i upgrade the gun to get better results?
