HF 20 oz gravity feed sandblast gun review and modification

[@StiNbJu]

Thanks for this mod video and sizing on bits/holes. I know this is 2 1/2 years old, but for folks that are coming here later, it does indeed say not to use sand. However, I found a decent work around to get consistent media size from Home Depot sandbox sand. I first put the sand out on a tarp to dry in the sun - Then use a mesh strainer you can get from Walmart/Target and filter into a milk jug/soda bottle through a funnel. It takes out the largest pebbles and gives a generally consistent media without clogging.

[@TotoGuy-Original]

you should use crushed glass instead of sand because sand is bad for your health some countries have band the use of it

[@coldspring624]

@@TotoGuy-Original stay off the sand beaches on a windy day right

[@rolfbjorn9937]

@@coldspring624 You don't blast the beach sand at high velocity on metal plates while breathing the dust though. The NO SAND warning is because of silicosis, a lung disease that's nasty and occurs quite fast when exposed to significant amounts of silica (sand, concrete, plaster and other dusts, even glass) either over time or in acute exposure.

Dude, you just saved me so much sanding. Tryed the gun yesterday, didnt work. Been procrastinating sanding the molding on 10 oak doors for my friend, your a life savour man !

Soda didn’t didn’t do anything to the powder coating I was trying to remove. Thank you so much for the help. Sand (dry sand) worked like a charm.

@@23steph13 I’d like to say it went well, and I did get it done. Works incredibly well. Just took about 8 times the length of this video. LOL But worth the effort.

[@richardberger414]

It does work out of the box if you use the proper media. Home Depot sand is made for a child's sandbox. It does not have a consistent grit size. I've used glass bead & aluminum oxide with great success. Moisture will clump the media and clog the gun, you need a water separator right at the gun.

Awesome video. Thanks for taking the risk on the modification of your new tool and for sharing with us!

[@TheNYgolfer]

Man you are a true blue Harbor Freight customer. Harbor freight sandblaster. Harbor freight cordless drill and those dangerous gold drill bitts that snap in a heartbeat . I drilled a piece once like you did. Held the piece to be drilled in one hand while drilling with the other. The bit snapped and I drilled right through my thumb with the broken bit that was left in the drill. What a bloody mess . I NEVER buy drill bits from Harbor Freight anymore.

[@vicjames2743]

Found me a new tool to have for my shop. The mods worked great. Thanks for sharing

[@tolikgord]

Great to hear!

[@johnasumaa8644]

I have the same tool. On page 8 of the instruction manual, under General Operating Instructions, it says "WARNING. Do not use sand for blasting." Further down, it states that compressor pressure should not exceed 90 psi. I had no problems, after reading the manual. That's what it's for.

[@5thGenNativeTexan]

Not sure which manual you're looking at, but that's not what it says. The warning is specifically regarding using sand with silica, and it's NOT that the unit can't use sand, the warning is specifically about breathing silicosis and aluminum oxide.

[@RedlandsBuzz]

thanks Anatoli. Mine worked out of the box but not as good as i wanted. Im gonna mod it like you showed.

[@mac2k2020]

oh it does work you just need to get proper blasting media sand from home depot is not good most likely too much moisture , works great with soda

[@SteveMirabelli]

When blasting with sand use at least a dust mask as silica dust is very hazardous to inhale.

[@LatinDanceVideos]

"silica dust is very hazardous to inhale." silica dust is really bad, it lingers in their air and doesn't settle, then becomes airborn. most states have banned it's use. it's worth the spend to go to a tool shop and buy the proper sandblasting media, plus get advice on the right material to use for your job.

[@Ezekiel-OffRoad]

@@LatinDanceVideos Blasting media is quite expensive especially if you don’t have a way to recover and recycle it I don’t agree with banning the use of silica sand just saying it’s dangerous or hazardous isn’t the best warning either they should put the definition of silicosis then people could make an educated decision to use a respirator or not

[@ronhancock4607]

@@Ezekiel-OffRoad Yup... lungs are more expendable. This video is dangerous, the sand is illegal in the US.

Just picked up one of these today along with a used 5.5 hp compressor for $70.00. Hooked everything up and loaded the gun with glass heads. I’m going to etch glass. Cut a stencil on my Cricut, stuck it on a glass I wanted to test on and it was fantastic. I live in SW Florida so humidity is a way of life here. Installed a desiccant moisture absorber in line and went to town. I am throughly empresses with thing. It does a great job.

[@mariebourn8317]

dumb question. when he drills out the gun he said all the way to? or through? the bottom? not through and through right?

[@wayawolf1967]

The "O" ring took you right back to a small opening.

[@danamcintyre3565]

I found that making sure sand is dry without moisture and i also siffted the sand makes it work great !

[@steadyeddie7453]

The most important factor in any media blasting is having the proper media. Home Depot sand is not made for sandblasting. It has tiny rocks, pebbles, and debris in the bag. You need either sand made for sandblasting, or you can filter your own sand through a screen to remove the larger particles that are clogging the valve and the tip on the gun.

[@ProleDaddy]

You're just talking about the fancy sandbox sand that you can get at HD.

[@frankviramontes139]

Awesome job on the modifications thanks ,thats exacly what I need it for ...

[@steelvet3133]

Thanks man! Great share! God bless you brother!

[@rob12449]

Holy Cow! Some hobbies should not be tried without researching the danger or hazards! When I saw you hold the metal with a bare hand and I was already concerned when you stated going to home depot for a bag of sand... If you accidentally pass that over your bare hand it can take off flesh. Sand is risky, even with a dust filter, when you take it off the dangerous dust is lingering in the air. Yes some sands are safer than others but why mess around, get some blast media.

[@msi4226]

whats the compressor psi you are using buddy?

[@machineman6498]

👍 will do this before using the one I bought. Thank you for making this.

[@vandresv]

I followed this recommendations and the blasting improved a lot, but still was not good for the task at hand. I was trying to remove old paint from a porch light and it failed miserably. My compressor does not hold 90 psi for more than a second or two, it drops to 60 very quickly, so that might be my problem and not the improved modified gun. Thank you.

[@greenisleoverland6469]

Hiya... Hope you are still responding 4 years on... Do you think this would be good for car brake callipers?

I gotta strip the paint off some old steel wheels for a repaint. Liquid strippers barely phase it. A 2400psi pressure washer with the needle tip does not phase it. Think this would do anything?

[@danbrownellfuzzy3010]

I found sacks of black grit at Menards. I think it was eleven bucks or so. It works great but you are constantly refilling the hopper. I tried baking soda today. I dont think it's as aggressive but it lasted a lot longer. I bought sand and it didnt go through, im sure glad it didnt, the comments said I would have Silicosis right now. I have a respirator so i might get a second gun to modify.

The capacity of the compressor only influences the possible duration of sandblasting. The grain size of the medium may be too coarse.

[@patrickperry6945]

I’ve had one of those for a long time. Has never performed properly, like yours. I’m gonna make those mods. Get a hood. Keep the media out of your face and hair. Also filter your media with a 5gallon bucket and window screen. You can figure out how. I used the bucket lid to hold the screen with about an 8 inch hole in it to hold the screen. I use play sand and filter (screen) it. Or you can get blasting sand from some hardware stores.
