Review - Harbor Freight 20oz Gravity Feed Blast Gun

- เผยแพร่เมื่อ 23 ต.ค. 2019
- I originally purchased this Central Pneumatic brand sand blaster gun to remove rust from my motorcycle frame, but I had a larger job to do on ceramic tile and brick so I review how well this small 20oz gravity feed blast gun held up and offer some thoughts on which air compressor is right for use with this sand blaster. I also discuss various blast media such as glass bead and walnut shell.

Rather than spend on a large compressor it's often convenient to add smaller compressors and connect them. While I use 3/4" air hose and Chicago couplings for my two industrial 5HP units you can run smaller hose between compressors and add all the extra tanks you desire for longer blasting before waiting for the air supply to catch up. The biggest inconvenience when home blasting is lack of air.
Thanks for watching and for adding your insights here. Agree, lack of air is the limiting factor, but if this gun received more air, the next limitation is the hopper size which drains pretty quickly. In the end, for folks who already own a modest sized compressor at home and need to blast on an infrequent basis, this thing is hard to beat for the $.
Your comment might have just been my saving grace. Thanks! 👍
I have been struggling doing my motorcycle frame using "Aircraft Remover", scraping the paint off, & then using a wire wheel on my grinder. This video convinced me to get a handheld sand blaster. Thanks.
I was happy I did, though I did get sand in my hair. Definitely wear some goggles that seal in your eyes. It gets everywhere. Worked great on my motorcycle frame though. 3 years later the new paint on my frame is looking great.
Great thorough review. I’m leaning towards this gun simply for ease of storage since I’ll barely ever use it.
I think you're touching on it's greatest utility. Thanks for watching!
Fantastic review! You did it just as I would. I'm flipping mowers so I just need to spot clean parts. Going to give it a try
Thank you for watching!
Thank you for the great review! Side note: CLR is great in removing the calcium build up on the tile without scratching anything
Thanks for watching! I address the CLR suggestion in another comment below. Do you a trick for applying it in sufficient quantity and dwell time so that it works?
@@UrbanMonkTV Ah, sorry. I figured that someone already mentioned the CLR. I would try to let it react for 5 min or so and then apply more on the scotch brite pad and see where this will get you.
@@ukrsindicat For what it's worth, a lot of time has gone by since I did this job and my pool is in need of tile cleaning again. I've hired a pro this time around as I'm too busy and they are going to bead blast like I did.
@@UrbanMonkTV Good to know. Let me know how it went!
I tried it on my shower did not work the CLR
I think I was using it almost wide open so it went quick . Maybe even a cardboard box with some holes cut for arms to capture media and re use .I just came home and fired up tie compressor , filled it up and had at it wearing eye and mouth protection but still got one in my one eye . I like it . Glad I got it . It’s for small things , small pieces . Not a car body but smaller spots
Media does go quickly.
That would be perfect for the project I have. I have an old vintage tackle box that has a lot of rust. I have plans on restoring it. I'll have to purchase one
Thanks for watching. Yes, it sounds like it would be a good fit for a project like that. Enjoy your project!
Thanks good information
I was looking for something to try a new craft
I think this will do what I need 👍🏼
Thank you for watching! Enjoy your "New Craft Journey!"
I think these guns agre great for using Bicarbonate of soda, or soda crystals on wood or cleaning alloy wheels. For removing rust you need a harder grit, but it then could etch your tile or glass surface, which you probably don't want. So my feeling is you need to choose the media carefully for the job and to suit the gun design, or use a different blast gun and higher pressure than 90 psi.
Thanks for watching and commenting.
Wow! I have tried to get my tile clean. I have a whole box of walnut shells. If it works I will be so happy. I almost went by your video. I also make glass pendants and this will be perfect instead of having a big box sand blaster.
Thanks for watching. FWIW, I have seen videos where people have built a box around this gun with success.
Bro , them glass beads had everything rolling off the table . I’d set a lack of cigarettes down and ot would start moving . I wasn’t aware the first time but then it made sense . I felt it with my hand and thought roller hockey game for the 70:s 👍👍. The good ol days are certainly the best remembered well . I used it for a titanium pocket knife scales and used a 5 gallon compressor barely got it done but just waited like you .
Thanks for watching.
thanks! My question is: (after sliding the container on the handle and screwing in the nozzle) Can I use this right out of the box? That's because it came with a tiny o-ring and 2 venturi screws that I don't know what to do with.
I would think so, but I don't recall mine coming with those extra/separate parts. Perhaps they've made changes to the product offering since I bought this one.
Great review, I've been thinking about getting one of those to make short work of my GL1000 restoration.
Thanks. I think for a small odd job here and there, it's money spent wisely. Save more $ to buy bikes! :)
20 bucks its worth it for small jobs
You're also pitting the tile so the buildup will be worse and harder to get off unless you reseal the tile before refilling the pool.
I did learn that after this video was shot and put a sealer on. Looked even better.
Thanks for the review sir.
Thanks for watching!
Nice review. Very helpful.
Thanks for watching!
Man this the video I need to see i think this smart watch is reading my mind thank man I know how remove the rust off my new trailer I done sand blasting on magnesium parts and bolts
Thanks for watching!
Good deal I have a vintage dirt bike with lots of small parts too go through
Perfect for small temporary jobs like that.
I wonder if you could modify the nozzle to get it to perform better? maybe fab a nozzle with smaller exit hole
Probably. My guess is they went large assuming customers would use without a dryer and they'd avoid clogging with larger nozzle. If you fabricated a smaller nozzle, I'd use dryer in air line. Thanks for watching!
I have a 33 gallon craftsman. 6.9psi at 90 cfm.
I can not get it to work for more then 20 seconds. It just stops, i have a regulator set to 90 psi, and have 2 water removal filters in my hard air lines....
I have used walnut 12 and 24 grit, and black diamond medium grade. None really work well. Should I try the fine grit black diamond?
I'm not really a sand blasting expert, so I don't really know how well one medium will work over another under different circumstances. Are you in a high humidity area? Are the water removal filters loading up?
There are coarse, medium and fine grade abrasives. Go with something fine with a little tool like this. You can blast with baking soda.
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?
Just a guess, but yes, it probably would. Stripped old paint off my motorcycle frame.
@@UrbanMonkTV I got one yesterday with some alum oxide media. made a temp cabinet out of a couple tarps and tables. Takes a while, but works pretty well. I have never been so insanely filthy. Full respirator and clothes you hate required.
@@jwandhistools Oh yeah. I used outdoors and was covered head to toe, but got the job done.
Also I don't think that you will burn off the air compressor by continuous operations. You will just see the reduction of air pressure once the air tank is empty
Well I didn't break the compressor but it sure did get hot. Thanks for watching.
Do you think this would work for pepping old cast iron pans for seasoning?
Yes, I am familiar with that process and I think it would work very well for that. Thanks for watching!
Thanks for the info buddy,I restore old dirt bikes and need something to blast the frames.😁
Thanks for watching!
Do you think it will clean up all the gunk or crystallize on the motorcycle engine?
Not sure I understand what you mean by "crystallize on the engine," but I think it would clean it. That said without actually having tried it on a gunky engine, but having tried it on several other surfaces.
@@UrbanMonkTV hi sorry I just saw you actually got a Gs550, I just picked up a 1980 GS550 and the engine is oxidized, and full of gunk in between the cooling engine part. I just wonder if you can sand blast the whole engine to make it shine like yours? Or i first sand blast it then polish it.
@@DeeBeeStudioSabah I think you could sandblast the engine case, cylinder and head. As for the clutch, stator and ignition covers, I sanded them with sandpaper and then polished. Enjoy your project! These are great little bikes!
Sweet, so my compressor isn't the issue, it just doesn't work as well when compared to the purpose built cabinets
Does this gun get into deep pitting in rust? Like the very fine tiny black pits?
It did on my motorcycle frame. That's the only experience I can offer that mirrors what you're asking. Hope it helps.
@@UrbanMonkTV I'm doing the roof of a car that has 8 year old rust. Got the rust completely gone down to bare metal but tiny little black pits that I can't grind through. Wondering if this tool is able to bounce media into those pits and clean them or if its a waste of time. Did you experience anything like that?
@@glytch5 Not exactly no, sorry. It may well do it though. It's only $20 to try.
Would you recommend for sandblasting a golf cart body?
Yes, absolutely. For one-time jobs this thing provides good results at a great price. Thanks for watching!
great video.
I have a 20 gallon compressor that produce 4.5 CFM @90 PSI. I tried walnut shell and did not work at all. nothing really came out of gun.
Do you think glass will work or my compressor just too weak?
Thanks for watching! If you weren't getting media out of the gun with walnut, I don't believe there's evidence you'd get glass out either. Guessing you're correct to assume compressor isn't up to the task.
drill the holes bigger on the adjustment shaft of the gun and r o ring the hopper watch fo center the one on shaft with a file night and day the gun will work well then outa the box its not very useful
Aluminum oxide
Can you use this with the HF 150.00 air compressor
I really can't answer that with any confidence. I've never used that specific compressor. Mine was under sized and still managed to get a big job done, but I made sure to give my compressor rests to cool down. A person could use the logic that if the HF compressor you mentioned has similar specifications to mine, it would work. However, the quality of the components used to make the two compressors could differ and therefore that approach will not answer the question either. Depends size of your job and how much time you take to do the job.
Everything is as he says 👍👍. Good video . 🙏 from Ohio
Thanks for watching!
Good video! Thanks for posting!
Thanks for watching!
Will it posibly remove anodizing on metals not just aluminum
I'd have to try it myself to answer that. It would certainly dull it, but removal is tough for me to say. Perhaps I'll get a chance to try it sometime soon. If I do I'll circle back here and leave a comment.
Wear a respirator even outside
Thanks for the FYI i haven't done something like this in quite a while
Use muratic acid for cleaning pool tile. 44oz to a five gallon bucket of water works great. I used to build pools and did a lot of rehabs on older pools
Thanks. Good looks
Use toilet paper for wiping your butt, even outside
What about a full face shield. PBeing in Oregon, im pretty tired of things over my mouth at this point (21.5/23 months with a mandate)
Will it work on a guitar pedal enclosure?
Assuming it's an aluminum case, yes. You would just want to be sure to clean it very well after, especially if the pedal in question has potentiometers in it like a wah wah or volume pedal. Thanks for watching!
it seems very weak output, what psi are you using? maybe increase it
Your question speaks to point I made in the video regarding the size of compressor. I was running it at 120 psi, but with such a small tank, the pressure drops fast. A larger tank and compressor would serve this gun well.
Can it remove exterior paint off of red brick house overspray
I haven't tested that situation specifically, but I will say yes with confidence that it'll remove any kind of paint off brick. Thanks for watching.
I saw a video quite a while ago, where the guy who shot the video used baking soda to do what you're doing here. It seemed to work well for him. I don't believe that it caused any abrasion to the tile he was cleaning.
Yes, that's called soda blasting and HF sells a different gun for that. I used this because O already owned it. Thanks for watching!
You should be wearing a respirator. Breathing blasting media can result in silicosis.
That is sound advice. Thanks. Speaking only to my own case, I use this tool extremely infrequently (thus why I bought an inexpensive tool). I don't worry much for myself, but agree with you that a person using this tool should wear a respirator.
Thanks for the review. I purchased this recently for doing small glass etching projects (frosted, not carved). I know I’m going to need a ceramic tip (5-7mm ID) for this using aluminum oxide 120 grit. I notice the tip has a ridge and I’ve seen similar ceramic tips, and others just straight sided. My question is: as long as I get one with the ridge and right OD (about 15 mm)…is this just a straight forward swap out?
Based on what you described, yes, I believe it would be straightforward. Thanks for watching!
Will this gun remove chrome from motorcycle parts?
I'd guess no. It'll just dull the finish. It'll rough up the surface nicely for painting if that's where you are heading.
Do you know if it would remove powder coating?
I believe it would, eventually. It would just take more time and media. Thanks for watching!
Good video
Thank you for watching!
Using the media blaster constantly how many minutes between refilling can you go?
Perhaps 2 minutes or so. My small compressor was the limiting factor. Thanks for watching.
Based on your input I'll buy this tomorrow to remove paint splatter on exterior brick facing. A little suggestion: ditch the music, please. Thanks for the video.
Thanks for watching.
Medium is too expensive ? I paid $10 for 5 lbs and it went quick . Maybe strain some finer sand
Straining would save some $
what blast media did you use?
80# glass bead in this video. Thanks for watching!
I use a water pressure sprayer on my fountain to remove the scale
That's a good idea.
So de Dewalt 15 Gal. 5.0 SCFM @90 PSI not work with this gun?
It'll work for short bursts, but you'll be pushing your compressor a lot on bigger jobs. Thanks for watching!
I was gonna ask what size air compressor.
Thanks for watching.
Yes, as stated in the video, I've got 13 gal capable of 5.5 scfm @90psi. Or bigger would be good.
Nice vid... my central pneumatic is a 21 gallon 125psi but only 4.7@90 and 5.8@40 😑😑
Someone keeps graffiti'ng up the front yard retaining wall. Then some guy showed up a few days after this week, claiming to be the city employee and saying we have 10 days to have it removed, mentioning he'll do it. Probably another scam during covid...
Thanks for watching. Sorry about your retaining wall.
Would this work for a job like Sandblasting some rims for powder coating ?
Yes it would. I used it on a motorcycle frame and it stripped paint nicely.
@@UrbanMonkTV wow. And you powder coated your bike frame?
@@BongoisaPyro No actually I painted mine, but considered it.
@@UrbanMonkTV hmm. I see, my plan is to powder coat some rims and I was thinking about picking this up and using some aircraft stripper first. Do they sell grits that are softer? So I don't cause pitting in the wheels?
@@BongoisaPyro you could try walnut shell. They sell that. More gentle, but might not be aggressive enough. You should try in a inconspicuous area.
Would this work for sandblasting glass
I don't know honestly. Never tried, but I'd guess it would. Not sure how efficiently.
Will it remove powder coat?
Hmm, good question. Honestly haven't specifically tried that, but in theory I think yes. Might take a little more time and media. Thanks for watching!
How long would a full hopper of sand last?
Balsting steady...Maybe 1 minute. Thanks for watching!
Acid and a scotch rite would have worked almost instantly and left the tiles perfect
I actually tried muriatic acid and Scotch Brite before I used this blaster and I had no luck with vertical surfaces. Couldn't get enough dwell time on surface for acid to make any progress. Thanks for watching!
does thsi work with walnut
I would think so but I haven't personally tried. Thanks for watching.
👍👍👍
Thanks for watching!
@@UrbanMonkTV Thanks for your thorough review! 🙏
Did you hog out the feed hole to 1/4 inch. its a game changer . I did, and it ripped it off with sand
I didn't, but have read of others doing exactly that with good results. I imagine it goes through media much faster that way. Thanks for watching!
'5hp' on the side of your air compressor, 120v 15 amps, how? Is that 5hp 'peak horsepower' or something? The math of that doesn't work out- you can't get that hp. out of 120v * 15 amps. Thanks for the informative video!
You've peaked my interest. I hadn't thought about that. I'm going to have to look into that. Thanks for watching!
@@UrbanMonkTV I just bought a used 220v 15 amp unit, and it says 5hp. 1 hp is equal to about 750 watts. Yeah the discrepancy *piqued* my interest. I have the exact same sand blaster, going to hook it up tonight and try it! I bought walnut shells, now I'm thinking they may clog the unit.
On the tile I would had tried a hand brush and vinegar.
I did that. Also tried steel hand brush and CLR. The stuff was hard. Thanks for watching!
@@UrbanMonkTV My area of Southern California has a high calcium reading. I brush the sides of my glass tile every week. There are water companies that will process pool water to get all the calcium out of your pool. It takes about 24 hours and they leave their truck overnight to process the water. It’s not cheap. It’s $800-1200 to do the job.
CLR would have been a good waterline test
I actually tried that and getting it to stay in contact with the surface for an extended period of time and in sufficient quantity was not working for me. Good thought for similar scale on a horizonal surface though. Thanks for watching!
Would play sand from Lowe'swork with this gun seeing that's it's so cheap by 50# bag?
That's a great question. Without actually trying it, it would be irresponsible of me to simply say yes, but from what I can see it should work. I believe the keys will be the moisture content of the sand and the size of the particles. Any wetness causes the gun to clog up and the purpose-made sand is very fine.
Do not use play sand. There’s silica in it which can cause lung damage. You do not want it in the air! Don’t use it!
Only if you're looking to get silicosis.
Where do you buy sand for these types of guns?
Harbor Freight or Northern Tool. There's probably others.
You will be all day with that thing you need a high power sandblaster
Yes, you're correct, it did take all day. I used it because I already owned it. Now that I don't have any sandblasting jobs to do, I'm happy with how little space the tool takes up in my shop and how $ is tied up in the thing. Thanks for watching!
@@UrbanMonkTV I've seen folks use some kinda torp for the sand to fall on so they can reuse it they just filter the trash through a screen
@@Mr.Frost181 I think that makes good sense, especially for someone who is doing blasting on a more frequent basis.
@@Mr.Frost181 ...and the fact that you use the word "folks" makes me like you right off the bat. 🙂
Just fill it with baking soda and it won't abrade your surfaces.
..
Thanks for watching!
You really should have know it would mess the tile up...
I strongly suspected, but it's right at the water line so it doesn't show up now that the pool is full.
Are you the russian cosmonaut from the movie Armageddon?
Thanks for watching. I've never seen that film, but yes, yes I am.
I ordered one from China, only the nozel came, didn't offer a second.
Good review but duh on the tile line
Thanks for watching.
for 21$ I couldn't pass
Thanks for watching. Yes, a lot of value for $21. I'm still using mine.
Try baking soda :)
Not the best... just mest up ur tile ... simple CLR or muriatic acid would do.
Appreciate your $0.02, but I honestly tried muriatic acid and CLR and getting enough on a vertical surface was proving difficult for me. Results were nil.
Music is too loud.
Wait a second..why wouldn't you use something like acetone and a scrub brush to remove scale on your pool walls? And why on earth would you remove base material from the surface of the pool walls with an abrasion application?? Your ignorance of masonry is prevalent as you successfully removed the glazing from the surface of those tiles that give them the qualities they're being utilized for to begin with.. This is beyond lazy and enters into the realm of ignorance. Thumbs down for misleading those not inclined to having basic common knowledge of general topics at their disposal. Please don't make any more videos without researching the content first.
I used this gun too remove my wife's dingleberrys
