This is a superb demo! Seeing the media running through your fingers is worth a thousand words! Doing glass is very useful to viewers. This is exactly how a demo should be. Very grateful to you. Also thank you for no obnoxious music. The natural sounds of media and your voice is music enough. Natural sounds educate, music irritates. Wish more UA-camrs would realize that. I think beach sand has salt, so stays damp and sticky. Try washing it out first, then running through the sieve. I bet it would work great if cleaned up with water first. Walnut hulls may work well with refinishing furniture. Eco safe, lung safe, gentle, cheap. Thanks a lot for the demos!!!
Did a double take when I heard you say Pensacola Beach. I own Pensacola Ironworks right off Palafox. We are literally neighbors! Thanks for the videos. Next time I’m on the other end of Palafox I’ll knock on your door!
Copy that. Our showroom only has about a half dozen products so we aren't much more to see than just a shipping warehouse, but come on by and we'll give you the tour. Thanks!
Just found Pensacola Beach on google maps. If I zoom out as far as google allows, we're only twenty four inches away on my monitor. So you're closer to us than Australia. So practically neighbours. 😁
Dang, I was really hoping for a visual table for which media was best for which application. Great testing and all, but I wish the conclusion were just a little bit better. In any case, thank you for sharing from so many years ago.
You saved me a lot of money and time. I'll give you an unsolicited piece of advice. If you are going to heat any kind of coating you need a multi filter full face mask because some of the resulting fumes will get you even before you can smell them
I swear by aluminum oxide. It cuts fast and feeds great. Currently using White Lightning white aluminum oxide from a local abrasive supplier. It comes in different grits like sandpaper. You can cut it with glass beads to achieve a smoother finish if desired. When purchased in 50 lb bags, it's not that expensive (I think I paid $40-50 for a bag) especially is it's going to re-used in a cabinet. Aluminum oxide does wear out eventually....every once in a blue moon, it's a good idea to change your media. I also use a carbide nozzle on my blast gun....not cheap, but totally worth it compared to ceramic or steel nozzles.
Agree with the aluminum oxide for fast work. It does leave a rough finish but that works out well if you are planning to paint the part. And the carbide nozzles are a must. The ceramic ones don't last with the alum oxide. For more finer and delicate work, like carbs, I like to soda blast. I dont have to worry about the soda getting where I dont want it. The soda simply washes away with water. Cheers.
Great sifters are designed for gold panning and dredging operations. You can get a whole ranged set of them. They stack and fit right into your 5 gallon bucket. Very precise sifting. No spilling at all. ..
Reason powder coat paint is hard to remove is because the baked paint is somewhat flexible and absorbs some of the impact from the blast media. Think of it as like rubber. Thus heavier weight and "spikey"/sharp particle media does better to remove it. Glass bead media, which is a more rounded particle will struggle for example. Great video!
Powder coat is a polymer resin, not a paint. It is NOT flexible. Best way to remove powder coat is with a torch or industrial stripper. Please educate yourself before spewing BS!
Correction - I called this material garnet, but the manufacturer called to alert me it's not technically garnet, it's 10X. 10X is a mineral based media and isn't technically not garnet. My bad...
Nice job.. that beach sand in that part of Florida is quartz but in most areas it it crushed up shell which is what we have in Texas. Believe me being a cheap ass I found out the hard way.
Thank you for this video! I have sandblasted off and on for years. Had my own business etching glass and blasting bear tracks in rock. I am starting to get back into it a little. Needed a refresh on media and this was perfect. The only thing I can add, if I remember correctly, is I think aluminum oxide doesn't break down as quickly as other media. Thanks again!
I wouldn't burn off powder coating because when I did my bull bar it gave off Hydrochloric acid vapour/chlorine fumes, both of which are incredibly dangerous. The acid fumes condensed out on various pieces of bare metal that generated rust within hours. Normally my workshop is very dry such that I can keep bare metal exposed for weeks without flash rusting.
So I’m an upholsterer and finally broke down and bought a harbor freight gun and some #24 walnut media instead of the #12 you tested. The rust I hit it with wasn’t quite as bad as your test panel and I had to put the nozzle of my gun right up to the rust, but it did come off. But I wasn’t too concerned about the walnut media mulching the edge of my yard where I cleaned my seat frames. Now that I have a blaster (and am getting a bigger air compressor), I’ll probably build a cabinet and consider a more aggressive media that is more reusable.
Excellent video! Flame stripping is a very old coating removal method. I use a weedburner (carefully on thin steel) for that and a handheld wire brush. I secure the work on my tristand (any outdoor vise will do) when it doesn't weigh enough to stay put. I keep pieces of scrap especially angle with bolt holes to hold all sorts of work in my vises. Walnut shell is so gentle it's been used in aviation by applying it to RUNNING jet engines where it removes accumulated carbon etc. It's very much a specialty item and I appreciate you testing it. Liked and subscribed.

If you have a chemical stripping company in your area, I feel it is the best way to go for body panels. The part is submersed in a stripping tank, so ALL the rust is removed, even in cavities and seams where you cant get with blasting. Then be sure to paint or seal in all the cavities and you will never have to worry about your trunk lid, door panel, etc rusting from the inside out. Just an option for folks. I also use my blast cabinet and outdoor blaster when appropriate. Thanks for the video.

Anything less than 17 cfm is useless for larger blasting projects) www.lowes.com/pd/MEGA-Compressor-80-Gallons-Two-Stage-175-Psi-Vertical-Air-Compressor/5014405385 Remember too, that these are noisy and the larger ones need 220V outlet, and they have a risk of exploding, so keep them in a sound-proofed, insulated cabinet.
Great video Very informative, Note of CAUTION though Always make sure You are not taking Sand from Beaches that prohibit this or You may face a hefty Fine, check the local laws first and make sure you ONLY take the permitted allowance if permission is granted.
Blasting with any silica sand is very very dangerous it can cause silicosis which cannot be reversed or cured and can cause death . It is illegal to use in many countries and has been for over 20 years in Australia ! Can't understand how it is still sold in the U.S and how commercial sandblasters can use it knowing that it is dangerous even in your air fed blasting helmet but anyone else working near by is at a far greater risk because they aren't aware of the danger and are just breathing it in with no idea it could kill them.
@@ABentPaperclipThe problem is the blasting process pulverises silica particles to micron/nano sizes, not your average sand particle sizes on the beach.
It’s the USA. We still have guns, millions and millions of guns in the hands of everyone. And you think we should make blasting with sand a criminal offense? Concerns over sandblasting caused silicosis or the extremely poisonous fumes when using resin in the fiberglass industry,… well, you must be responsible first for your OWN safety. Then, secondarily, you must be responsible for employees’ safety. Being responsible for your OWN safety means you will guard yourself against being sued by injured employees who choose not to follow safety protocols. You must fire those who are too ignorant and of such low IQ that they cannot work safely. Such is life, and for many, life is hard and short.
@dwainseppala4469 if you don't like people here having guns and think it's any of your business I suggest you put your money where your mouth is and come and try to take them yourself. Otherwise just play your video games and be glad there are people like us to provide you a blanket of freedom to sleep under
Obviously they aren't gonna ban sand... as if you could even do that... there's a thousand different things you might need to buy sand for that have nothing to do with blasting. They also sell sand specifically for blasting without the silica content.
I bought a 5g blaster direct from VEVOR when I got most of it was together my only concern is when I hooked up the blast gun hose to the bottom of the tank it went on really easy it seemed very loose fit I tightened the hose clamp real good and I can still spin the hose around and around I'm not sure if it is suppose to do that or not. My thinking is yes because of all the different hoses it has this would be the one that you would want to spin depending on how you prefer to hold the blast gun, please get back to me ASAP thanks Wally
Why the hell didn't i watch this before doing it. i bought the black copper slag and it was useless, clogging up the gun waste of tine. BIG mistake. . Fantastic video. thanks.
I used to live in niceville around the fort Walton and Destin area myself. That Quarts sand is amazing stuff. When you bring it back from the beach it's in your car and house for life lol. It sticks to everything. Even turns oil slicks into tar balls. And lighting loves the he'll out of it. It's a great conductor of electricity. That why things around there get wacked by lighting so much. I just wonder being it's been in salt water. If flushing it with fresh water then drying it would make it less corrosive to the metal your blasting. So you don't end up with rust under the paint job. I'm just thinking of possible salt contamination to the metal. Just possible food for thought, possibly what are your thoughts on this?
I can tell you this for sure. At the beginning of this Nova project I blasted some parts with play sand from Home Depot. I epoxy primed one of those parts and set it outside with only primer. Years later, it looks great.
Only thing I'm thinking with beach sand well ocean beach sand is I imagine it would have a high salt content and that's not all that desirable blasting say mild steel, I would think it could really beat that salt into the pores causing instant rust issues...?
I have an all original 1957 chevy engine and powerglide for sale. It has the power pack heads and the Carter car along with the proper breather and generator.
aluminum oxide is what i use and it's great for steel and aluminum for my powder coating, but after i use it and outgas it, then ill put it my other blast cabinet that has glass media, to fine out areas that are needed works great....im getting ready to buy black diamond fine and medium , what do you think about using it replace it with the glass ??? please let me know thanks
@@RedlineStands Thank you I appreciate your response. 10.00 a bag of black diamond fine, isnt gonna hurt my budget, so i'm gonna give it a try, and ill let you know the results and different application difference..if any !!!.. Happy New Years from my shop to yours
Great video I enjoyed very much. What psi were you using in your demo ? I use the glass bead 80 grit on painted, rusted cast iron and stamped steel which does pretty good in my blast cabinet. I might give the 70-100 mesh 10x a try and see how that works.
Very informative. Which media produced the least amount of dust inside a cabinet? I am going to purchase your REPP70 pressure blaster. I have a 40 hp diesel screw compressor I plan to keep outside and run the air in. It produces 100cfm at 100psi. It amazes me how small increases in nozzle size increase tremendous amounts of air flow. With a 1/4 inch nozzle I need 85 cfm. What size nozzle can the REPP70 use? Thank you
In my REPP70 at home I like to run either a 6mm or 7mm nozzle and that works well for me, but then again I only have 17 CFM to work with, but I make do just fine. I'd say the 10X produces the least amount of dust. Crusted glass gets really dusty fast.
@@RedlineStands actually you don't even have 17cfm unless you are blasting at 40 psi. at 90 psi you have 15 cfm. plastered clear as day on you compressor.
Thanks, Enjoyed. I am trying to remove decades of paint from an upright metal belt sander. Rockwell made in 1942. I have a large blast cabinet and first tried soda. Poor performance. Plan B.
Soda is meant for more delicate parts, like carbs and soft aluminum. To remove "decades of paint" quickly I use aluminum oxide with a carbide nozzle. I restore vintage metal and woodworking equipment and the al/ox works best. Plus, it provides a nice finish for my primer to grab.
QuickCrete is the brand, so it's just sand, not QC and sand. I have used a good 3M respirator in the past and experienced no health problems after a full day of blasting. With that said, do not use a dust mask. You definitiely need something much better.
Yes there is a health hazard with any blasting operation, but especially with silica sand. In my 37 years in the equipment rental business, including many types of blasting equipment, I would say "NO", a respirator is not safe enough. Even a Positive Air Pressure device leaves traces of highly abrasive in your lungs, which you will need for the rest of your life. People breathe more than 10 times more air than they eat food by weight.
I bought that screen material many years ago so I don't recall. Today we sell this sifter in the link below and it works great. www.redlinestands.com/catalog/shop-equipment-c-327/sand-blast-equipment-c-327_501/sand-blast-accessories-c-327_501_506/5-gallon-buckettop-blast-media-strainer-filter-p-3056
That's really tough to say. It depends on what you plan to do with the metal once you're done. For instance, is it aluminum? If so, are you going to polish it? If so, you will want soda because anything else will leave the metal badly pitted and would require sanding in order to polish it. Are you powder coating it? If so, then a lot of pitting is great, and I'd recommend something cheap like crushed glass or 10X.
@@terryrowles7703 It's probably powder coating. If you'll hit it with a propane torch and burn the coating really well it'll become brittle and will blast off easily.
@@RedlineStands Oh I didn't know that. I suspect all of those abrasives are deadly when they get ultra fine powdered and inhaled. I mean glass is the same as sand and garnet will get just as fine as glass. Gotta wear EFFECTIVE breathing protection. Thanks for the warning. ..
@@MrDavePed I Understand the Point being made, what I don't understand is how Marines can drive through the Dessert, for 18 days at a pop, Get covered from Head to toe with enough sand, they have to put bandannas on their faces to breathe, then spend hours cleaning that gritty crap out of everything. Trust me when I tell you that sand is about as fine a particle as you're gonna find after being ground up by 5 Ton Trucks and 15000 Lb. Howitzers or Tracked Vehicles, Yet, they still do this today!?!! I am glad to see so many people erring on caution though, sharing this information is working, Thanks Everyone!
At the time of this video....17 cfm and 5Hp. ...Today... 34 cfm and 10 hp... If you're thinking of blasting with 5 hp, make sure to set aside your saturday...
im disappointed a man of your age does not know the correct Star Wars quote you referenced. great video though, thank you for all the data you complied.
So I have no idea if that's true or not. Maybe it is. If it was, I'd still have done the video just the same. I feel like I showed the medias people wanted to see being used. The video is at 156K views today. To me, that indicates that people are interested in what they're seeing and are finding what they hoped to find.
Something like this? www.redlinestands.com/catalog/cool-stuff-c-286/racing-go-kart-stands-c-286_249/all-go-kart-stands-c-286_249_117/streeter-standard-racing-go-kart-stand-p-770
You're absolutely wrong about the aluminum oxide! For some things, it's the cheapest Media you can get because it's infinitely recyclable granted you're using a cabinet. For some things, there is nothing better.
Beach sand, builder's sand, brick and block sand and play sand are not the best cutting materials. All of the above are rounded by the action of wind and water, and appear like ball bearings under magnification. Blasting sand looks like shards of broken glass with lots of "sharp" edges, before first use. Most media can be reused. Blasting sand can be reused up to about 4 times before it is no longer economical. Sharp blasting sand is manufactured by fracturing silica deposits, before drying and packaging, and must be kept dry for best results. Sieving and cleaning media is time consuming and therefore expensive. Silica, like asbestos, is an extreme respiratory hazard. Silicosis, also know as tunnelitis, killed at least 764 men working on the Hawks Nest Tunnel, alone. Other media, while being initially more expensive, may be less expensive when reused. The Kobalt air compressor is not capable of 17 CFM at 155 PSI. 155 is the max pressure, and 17 CFM is the cubic feet per minute at 40 pounds per square inch (PSI). PSI is like electrical voltage, and CFM is like current (AMPS). To determine power, multiply CFM by PSI. In use while blasting, the actual air pressure will drop to near zero, so therefore. flows more volume (CFM} Than specified. Good job on the video. I hope your wife forgives you.
Be careful. It is illegal to remove sand from a 'beach'....state beach, county, city beach etc.. Tourists get away with small bottles but don't get caught walking away with a pail full..... I prefer buying bags of 'play sand' at Home Depot or Lowes, but, sift it! At least it's dry LOL
Illegal to remove but not to blast with? Can cause death but don't get caught walking away with a pail full? Tourists steal small bottles of sand??? A pail full must be a felony hope it's not your 3rd strike
@@catatonia1 Just answer your own questions and you'll be fine. Personally I would NOT remove any sand of any amount from any government owned beaches....... You need dry cleaned bleached sand.
Absolutely ZERO mention of silicosis from this guy at all means i cant take this man seriously. The physical demos he didcspeak for themselves but thats all I'd pay attention to.
i use aluminum oxide. but i recycle it till it is powder. beach or hardware sand, works about two or three times, before all the sharp parts are rounded off, ,blackjack is a little better, but still gets smooth, a lot sooner than the aluminum oxide . for a single run, it is great and cheap, on my cabinet recycling it. not so much, great vide thanks
_"...running 17 CFM @ 155 PSI"??_ But the specs for that compressor are: 17.3 SCFM @ 40 PSI 16 SCFM @ 90 PSI 17.3 SCFM @ 40 PSI And _pressure_ (PSI) changes _inversely_ to _CFM_ (volume) - so the higher the pressure the lower the CFM. I'm guessing dude just misspoke since the "Max PSI" printed on that compressor is "155". But who knows what the SCFM would be a max 155 PSI. I'm not calling anybody out, it's just important to know exactly what settings are being used.
Glad to hear it was helpful for you. Really thought when I made this video that the content was good enough to garner more than 11k views in 2 years but oh well.
@@RedlineStands I agree with you. I’m sandblasting for the first time and based on my search today there’s not much else on UA-cam with your scope and specificity.
@@andyspoo2 if you think a mask is sufficient then you are sadly mistaken. A respirator at the very least. But hey it won't hurt me in the slightest what you use. So by all means.
If you are going to do some serious blasting a siphon system is useless. Use a pressure pot. You will also need serious amount of air. 5 horse compressor is pretty well useless also. A superb media is Dupont Starblast XL.
This is a superb demo! Seeing the media running through your fingers is worth a thousand words! Doing glass is very useful to viewers. This is exactly how a demo should be. Very grateful to you.

I think beach sand has salt, so stays damp and sticky. Try washing it out first, then running through the sieve. I bet it would work great if cleaned up with water first.

Here is the closest match for $2250 and they don’t mention CFM (air movement at Cubic Foot per Minute - the most important factor in blasting. Anything less than 17 cfm is useless for larger blasting projects)

Remember too, that these are noisy and the larger ones need 220V outlet, and they have a risk of exploding, so keep them in a sound-proofed, insulated cabinet.
I'm in beginning of video but appreciate notes I am screenshotting them now thx
Great video Very informative, Note of CAUTION though Always make sure You are not taking Sand from Beaches that prohibit this or You may face a hefty Fine, check the local laws first and make sure you ONLY take the permitted allowance if permission is granted.
Blasting with any silica sand is very very dangerous it can cause silicosis which cannot be reversed or cured and can cause death . It is illegal to use in many countries and has been for over 20 years in Australia ! Can't understand how it is still sold in the U.S and how commercial sandblasters can use it knowing that it is dangerous even in your air fed blasting helmet but anyone else working near by is at a far greater risk because they aren't aware of the danger and are just breathing it in with no idea it could kill them.
Should we be wearing a respirator if we want to go to the beach on a windy day?
@@ABentPaperclipThe problem is the blasting process pulverises silica particles to micron/nano sizes, not your average sand particle sizes on the beach.
It’s the USA. We still have guns, millions and millions of guns in the hands of everyone. And you think we should make blasting with sand a criminal offense? Concerns over sandblasting caused silicosis or the extremely poisonous fumes when using resin in the fiberglass industry,… well, you must be responsible first for your OWN safety. Then, secondarily, you must be responsible for employees’ safety. Being responsible for your OWN safety means you will guard yourself against being sued by injured employees who choose not to follow safety protocols. You must fire those who are too ignorant and of such low IQ that they cannot work safely. Such is life, and for many, life is hard and short.
@dwainseppala4469 if you don't like people here having guns and think it's any of your business I suggest you put your money where your mouth is and come and try to take them yourself. Otherwise just play your video games and be glad there are people like us to provide you a blanket of freedom to sleep under
Obviously they aren't gonna ban sand... as if you could even do that... there's a thousand different things you might need to buy sand for that have nothing to do with blasting. They also sell sand specifically for blasting without the silica content.
What a great video🥳
Like the set up.
Very informative and that I appreciate.
I bought a 5g blaster direct from VEVOR when I got most of it was together my only concern is when I hooked up the blast gun hose to the bottom of the tank it went on really easy it seemed very loose fit I tightened the hose clamp real good and I can still spin the hose around and around I'm not sure if it is suppose to do that or not. My thinking is yes because of all the different hoses it has this would be the one that you would want to spin depending on how you prefer to hold the blast gun, please get back to me ASAP thanks Wally
No sir. Definitely not. That hose should be Jesus tight.
Excellent video! Although it would have been awesome to see comparing the 20/40 glass with 40/70
Very informative. Thank you.
Great video!!! 👏👏👏😍😍😍
Why the hell didn't i watch this before doing it. i bought the black copper slag and it was useless, clogging up the gun waste of tine. BIG mistake. . Fantastic video. thanks.
I used to live in niceville around the fort Walton and Destin area myself. That Quarts sand is amazing stuff. When you bring it back from the beach it's in your car and house for life lol. It sticks to everything. Even turns oil slicks into tar balls. And lighting loves the he'll out of it. It's a great conductor of electricity. That why things around there get wacked by lighting so much. I just wonder being it's been in salt water. If flushing it with fresh water then drying it would make it less corrosive to the metal your blasting. So you don't end up with rust under the paint job. I'm just thinking of possible salt contamination to the metal. Just possible food for thought, possibly what are your thoughts on this?
I can tell you this for sure. At the beginning of this Nova project I blasted some parts with play sand from Home Depot. I epoxy primed one of those parts and set it outside with only primer. Years later, it looks great.
THANK YOU!
I've got an old rusty truck frame that you can practice on Dude !🇺🇸☺️👍
Only thing I'm thinking with beach sand well ocean beach sand is I imagine it would have a high salt content and that's not all that desirable blasting say mild steel, I would think it could really beat that salt into the pores causing instant rust issues...?
Oh I agree completely. I did this test because people love to see all sorts of demos and comparisons on UA-cam
Nice tutorial love it
Thank you for making this
I have an all original 1957 chevy engine and powerglide for sale. It has the power pack heads and the Carter car along with the proper breather and generator.
aluminum oxide is what i use and it's great for steel and aluminum for my powder coating, but after i use it and outgas it, then ill put it my other blast cabinet that has glass media, to fine out areas that are needed works great....im getting ready to buy black diamond fine and medium , what do you think about using it replace it with the glass ??? please let me know thanks
I don't understand your question sir
@@RedlineStands does black diamond work the same as aluminum oxide ? performance wise ?
@@417plasma6 Never tried it. With that said, I have never met anyone who thought anything worked as well as aluminum oxide.
@@RedlineStands Thank you I appreciate your response. 10.00 a bag of black diamond fine, isnt gonna hurt my budget, so i'm gonna give it a try, and ill let you know the results and different application difference..if any !!!.. Happy New Years from my shop to yours
Great video I enjoyed very much. What psi were you using in your demo ? I use the glass bead 80 grit on painted, rusted cast iron and stamped steel which does pretty good in my blast cabinet. I might give the 70-100 mesh 10x a try and see how that works.
How about synthetic olivine pyroxene sand for blastig body panels?
Very informative. Which media produced the least amount of dust inside a cabinet? I am going to purchase your REPP70 pressure blaster. I have a 40 hp diesel screw compressor I plan to keep outside and run the air in. It produces 100cfm at 100psi. It amazes me how small increases in nozzle size increase tremendous amounts of air flow. With a 1/4 inch nozzle I need 85 cfm. What size nozzle can the REPP70 use? Thank you
In my REPP70 at home I like to run either a 6mm or 7mm nozzle and that works well for me, but then again I only have 17 CFM to work with, but I make do just fine. I'd say the 10X produces the least amount of dust. Crusted glass gets really dusty fast.
@@RedlineStands actually you don't even have 17cfm unless you are blasting at 40 psi. at 90 psi you have 15 cfm. plastered clear as day on you compressor.
Thanks, Enjoyed. I am trying to remove decades of paint from an upright metal belt sander. Rockwell made in 1942. I have a large blast cabinet and first tried soda. Poor performance. Plan B.
Soda is meant for more delicate parts, like carbs and soft aluminum. To remove "decades of paint" quickly I use aluminum oxide with a carbide nozzle. I restore vintage metal and woodworking equipment and the al/ox works best. Plus, it provides a nice finish for my primer to grab.
Why remove the soda? Tell us what good it is for. At least.
is there the health hazard with quick Crete and beach sand. If so, does a good respirator
safe enough?
QuickCrete is the brand, so it's just sand, not QC and sand. I have used a good 3M respirator in the past and experienced no health problems after a full day of blasting. With that said, do not use a dust mask. You definitiely need something much better.
Yes there is a health hazard with any blasting operation, but especially with silica sand. In my 37 years in the equipment rental business, including many types of blasting equipment, I would say "NO", a respirator is not safe enough. Even a Positive Air Pressure device leaves traces of highly abrasive in your lungs, which you will need for the rest of your life. People breathe more than 10 times more air than they eat food by weight.
hi could you tell me what size screen you use to clean or shift the media ? thanks great video.
I bought that screen material many years ago so I don't recall. Today we sell this sifter in the link below and it works great.

I found the Black Diamond coal slug works on everything Especially on rust
We just picked up 100lbs for $20. Have not tried it yet.
Is there any that can take gun coatings off and maybe polish it a little
What media would you suggest for sandblasting paint off leather that wouldn’t damage it?
I'd maybe try walnut shell first. Very unabbrasive.
Thanks.
I'm told that the railroad uses walnut shell to clean up brass air break parts without damaging the surface finish.
what type of media is best fro removing a coating on a 1985 Kawasaki motorcycle frame>? The stuff is very thick not sure but mite be plastic coat?
That's really tough to say. It depends on what you plan to do with the metal once you're done. For instance, is it aluminum? If so, are you going to polish it? If so, you will want soda because anything else will leave the metal badly pitted and would require sanding in order to polish it. Are you powder coating it? If so, then a lot of pitting is great, and I'd recommend something cheap like crushed glass or 10X.
@@RedlineStands Hi it is being powder coated, i'v tried crushed glass it dose not work on this coating what ever it is?
@@terryrowles7703 It's probably powder coating. If you'll hit it with a propane torch and burn the coating really well it'll become brittle and will blast off easily.
@@RedlineStands I'll give that a try thanks good video keep it up..
As I understand it, unless you are sure the sand you are using is silica free it shouldn't be used, Silica dust is very bad for the lungs.
Yeah That's why I ware a full face old military Gas mask when using sand all internals clean as a daisy after blasting.LOL.jim
@@TheShawna1 You can't filter out the silica dust with a mask.
@@TheShawna1 Silica sand stays in the air for days after being blasted. It should never ever be used.
@@TheChrisey Yes you can.
A lead, asbestos filter on your respirator should be good for silica as well. Just make sure you have done a good fit test before the task.
Too funny :) Beach sand is the best (FREE!!) just make sure it is sifted out and dry thanks much !
No sir/ma'am. Please don't use beach sand. It contains free silica, will give you silicosis when blasting with it, and will kill you.
@@RedlineStands Oh I didn't know that. I suspect all of those abrasives are deadly when they get ultra fine powdered and inhaled. I mean glass is the same as sand and garnet will get just as fine as glass. Gotta wear EFFECTIVE breathing protection. Thanks for the warning.
..
@@MrDavePed Correct. It's all terrible to inhale, but some are much worse than others.
@@MrDavePed I Understand the Point being made, what I don't understand is how Marines can drive through the Dessert, for 18 days at a pop, Get covered from Head to toe with enough sand, they have to put bandannas on their faces to breathe, then spend hours cleaning that gritty crap out of everything. Trust me when I tell you that sand is about as fine a particle as you're gonna find after being ground up by 5 Ton Trucks and 15000 Lb. Howitzers or Tracked Vehicles, Yet, they still do this today!?!! I am glad to see so many people erring on caution though, sharing this information is working, Thanks Everyone!

What compressor are you using?
At the time of this video....17 cfm and 5Hp. ...Today... 34 cfm and 10 hp... If you're thinking of blasting with 5 hp, make sure to set aside your saturday...
"...taken from the beach..." -- NEVER use beach - QUESTION" What is usually at the beach? SALT - and never use sand - SILICOSIS of the lungs..
pneumonoultramicroscopicsilicovolcanoconinosis
Does 20/40 mesh garnet works on 6mm nozzle?
Probably, but I'm not willing to guarantee it.
im disappointed a man of your age does not know the correct Star Wars quote you referenced. great video though, thank you for all the data you complied.
LOL. I'm not a virgin, so my Star Wars quotes are gunna be a little rusty.
@@RedlineStands damn, sir well played, well played…
All blasting media types you showed have a major disadvantage. Abrasive particles are left stuck/embedded in the metal.
So I have no idea if that's true or not. Maybe it is. If it was, I'd still have done the video just the same. I feel like I showed the medias people wanted to see being used. The video is at 156K views today. To me, that indicates that people are interested in what they're seeing and are finding what they hoped to find.
tried crushed glass/ aluminium oxidise/ none of them work...?
What are you blasting, what is the substrate?
Should have tried copper slag or coal slag although coal slag will imbed itself into the metal.
What was that that u used to hold the body of the car?
Something like this?

Is the nozzle inside your gun?
Yes sir
You're absolutely wrong about the aluminum oxide! For some things, it's the cheapest Media you can get because it's infinitely recyclable granted you're using a cabinet. For some things, there is nothing better.
Beach sand, builder's sand, brick and block sand and play sand are not the best cutting materials. All of the above are rounded by the action of wind and water, and appear like ball bearings under magnification. Blasting sand looks like shards of broken glass with lots of "sharp" edges, before first use. Most media can be reused. Blasting sand can be reused up to about 4 times before it is no longer economical. Sharp blasting sand is manufactured by fracturing silica deposits, before drying and packaging, and must be kept dry for best results. Sieving and cleaning media is time consuming and therefore expensive. Silica, like asbestos, is an extreme respiratory hazard. Silicosis, also know as tunnelitis, killed at least 764 men working on the Hawks Nest Tunnel, alone. Other media, while being initially more expensive, may be less expensive when reused. The Kobalt air compressor is not capable of 17 CFM at 155 PSI. 155 is the max pressure, and 17 CFM is the cubic feet per minute at 40 pounds per square inch (PSI). PSI is like electrical voltage, and CFM is like current (AMPS). To determine power, multiply CFM by PSI. In use while blasting, the actual air pressure will drop to near zero, so therefore. flows more volume (CFM} Than specified. Good job on the video. I hope your wife forgives you.
P.s ... just off hand , the more psi ... the better finish
Which shots i can use for aluminum casting??
No one knows
Careful about saying you took beach sand from Florida. There's laws against it.
great video, however with that big tip you were wasting a lot of blast media.
What can I use to remove paint from chrome
I'd use a chemical stripper to keep from damaging the chrome. Read the label first and buy anything made by 3M.
Plastic. It will strip the paint without damaging the undersurface. Ideal for blasting soft metals like aluminum, brass, etc.
Glad to see the internet police have come and inspected this video. 🙄
Be careful. It is illegal to remove sand from a 'beach'....state beach, county, city beach etc.. Tourists get away with small bottles but don't get caught walking away with a pail full..... I prefer buying bags of 'play sand' at Home Depot or Lowes, but, sift it! At least it's dry LOL
Illegal to remove but not to blast with? Can cause death but don't get caught walking away with a pail full? Tourists steal small bottles of sand??? A pail full must be a felony hope it's not your 3rd strike
@@catatonia1 Just answer your own questions and you'll be fine. Personally I would NOT remove any sand of any amount from any government owned beaches....... You need dry cleaned bleached sand.
Never mind the fact it's going to have salt in it most likely unless is from a beach on a pond
Not a good idea to use beach sand or play sand. Silica powder is bad for your lungs.
Absolutely ZERO mention of silicosis from this guy at all means i cant take this man seriously. The physical demos he didcspeak for themselves but thats all I'd pay attention to.
i use aluminum oxide. but i recycle it till it is powder. beach or hardware sand, works about two or three times, before all the sharp parts are rounded off, ,blackjack is a little better, but still gets smooth, a lot sooner than the aluminum oxide . for a single run, it is great and cheap, on my cabinet recycling it. not so much, great vide thanks
Beach sand bonds with salts n minerals. Even ugh it can be washed n entilated
_"...running 17 CFM @ 155 PSI"??_
But the specs for that compressor are:
17.3 SCFM @ 40 PSI
16 SCFM @ 90 PSI
17.3 SCFM @ 40 PSI
And _pressure_ (PSI) changes _inversely_ to _CFM_ (volume) - so the higher the pressure the lower the CFM. I'm guessing dude just misspoke since the "Max PSI" printed on that compressor is "155". But who knows what the SCFM would be a max 155 PSI. I'm not calling anybody out, it's just important to know exactly what settings are being used.
Powder coat is good stuf...
Dosnt play sand have silica in it ?????? Wtf
This was really interesting. The results are not intuitive for me at all.
Glad to hear it was helpful for you. Really thought when I made this video that the content was good enough to garner more than 11k views in 2 years but oh well.
@@RedlineStands I agree with you. I’m sandblasting for the first time and based on my search today there’s not much else on UA-cam with your scope and specificity.
You should consider trying childrens play sand. It's pre-sieved, and usually dryed out.
sand has silica and if you value your health it should be avoided. ever heard of silicosis?
@@lunger2006 Ever heard of a good quality mask? Or were you asleep during covid??

Please don't steal Beach sand people...
Looks to me like the amount of material flowing through the gun needs to be turned up, give it more material
If you are going to do some serious blasting a siphon system is useless.
Use a pressure pot.
You will also need serious amount of air. 5 horse compressor is pretty well useless also. A superb media is Dupont Starblast XL.
What do you recommend would be the minimum specs for a compressor?
