I made one just like this today and the blast cabinet works a lot more consistently. Thanks for the video I had some extra 1/2" PVC pipe laying around and a cap so it was essentially a free mod.
Kevin, thanks for your sandblaser (siphon) suction tube plastic pipe upgrade, right on the money. Matter of fact, I'd rate your upgrade as one of the best on RUclips by far. Why? Because it is simple and absolutely works. Period! Also if you drill 1/8" hole on top siphon (where air line is connected and clamped) the hole ejects air for smoother transition of abrasive medium...
I've seen a few videos on this topic, but I think everyone is over thinking it. I simply drilled the outer tube on the harbor freight pickup full of small holes and it works fine now. Before that it was only working sporadically.
Years ago I made a sandblast cabinet out of a 55 gal drum. I never had much luck with a siphon type gun. I ended up buying a pressure pot. It made a huge difference.
Building our own too: watching this -like watching paint dry, OR slowly blasting an object with the wrong setup, etc. Rather you than me - so thankyou for taking the time to do all this and show us that we may not waste our time doing what you've had to do. One one'll always learn from others. take care
Thank You Mr. Robinson. Had feed issues w/ HFreight Item 37025 since it came out box. Made a siphon tube like yours, but used some pieces of PEX lying around and it works great!
Hey Kevin. I made a pickup tube as you described with one exception. I drilled a hole directly below front two holes so you can see through from bottom pipe to top pipe. Then made a bracket to hold the tubes on bottom of blast cabinet. It works so well i had to tell you. I have a small jobsmart blast cabinet that came from tractor supply. 😎
Bring water to a boil in a coffee cup and then take it out of the microwave and hold the end of the hose in the water for about 20 seconds of so. Then you'll find it slips over things easier but maybe taper sharp edges first so it won't catch while sliding on.
i am doing this right now .i have fitted bigger bore hoses and ditched the regulator which came with the second hand cabinet ..already one on my compressor which seems to allow higher / more pressure ..that quick release on your gun may not be helping as most have a smaller bore ..i was on the verge of dumping mine but the bigger bore hoses has made a massive difference ....but still going to try your plastic pipe for even better results
Make sure your blast mix does not contain sillica cause it will ruin your lungs. Thanks for the upgrade. I am struggling with that very same issue. Out of the box- it doesn't work well AT ALL.
I have the same sandblaster gun and same cabinet. The suction tube clogs every 10 seconds. I have to use my finger to block the nozzle to force the air to blow out the media that clogs the suction tube.
Well I'm almost a year later on this video , my cabinet was ok but the gun would pulse as it sucked up the media same as yours single tube shoved in the media . I'm heading to trying this double tube method and seeing you have a continuous supply of media out the gun is promising. Thanks for the demo
Depending on what abrasive you use , make sure the filter in your vacuum is rated for it. I always use the green HEPA 5 filter in my ridgid vacuum it is the best one they offer.
What about for 50 micron glass beads? I’m using them for polishing plastic with a vapor honing gun. Isopropyl alcohol comes in clean, and the air picks up the glass beads otw to the vapor honing gun. I’m having to run my psi too high to get enough beads up from a siphon gun. Smaller holes? I need more media at lower pressure (30psi) but not so much media I use it all up in 5 minutes. Any ideas?
Great video Kevin. I have been wanting to buy a sand blaster for a while now. Like you I have watched lots of RUclips videos on them. That powder coating is tough. The plant I used to work at had an industrial cabinet that didn’t want to take it off either so we would have to wire brush the part a little before putting it in the blaster. That seemed like enough for the sand to get under the powder coating. Thank you for sharing
Not sure about all powders but I soaked a powder coated part of mine in acetone the other day and made it soft as butter. If not acetone I imagine MEK would do the trick or some methylene chloride based stripper.. but be seriously careful with those last two.. acetone is bad enough, MEK and mc strippers are serious chems
I learned a burping technique from a friend who had never modified his draft tube. When his tube plugged up he would hold his glove over the nozzle of the gun and force air back down the pick up tube which will clear the clog. So in this case burping isn’t rude.
Hi Kevin- I am kinda lost when it comes to the siphon tube? I might have it all wrong but it looks like to me that it is just not picking up enough of the Blk sand what is the thought behind the second pick up tube? What I thought I seen was the top of the capped tube was out in the open and not down in the sand maybe I missed something but it seems to me that you are loosing some of your vacuum thru the top of that tube & thru the hole that you drilled - if you understand what I am trying to describe either that or I totally missed how the new siphon tube is supposed to work - Thanks for the video my friend! Two Thumbs Up
is the black beauty sand to aggressive? i thought the metal looked a bit pitted after the blast...tho I could not see clearly in the video . what would you say ? also do you have a link to the site or place where they have that black diamond sand? I want to know if there is a place near me with it that i can get it as well.
To remove powdercoated finish you need air craft remover and strip it prior so that it is wrinkled and dry .. I have a professional grade blasting cabinet with 10hp compressor and life is way to short for me to remove powdercoated finish with cabinet and im retired .. you would need tens of thousands of dollars invested to remove powder coated finish with a blasting set up and it would be very harsh on whatever material besides steel or iron. iron oxide media works but it is rough on parts . I like to use glass bead
Tractor supply has it picked up bag and a bucket of glass media also harbor freight carry’s meds as well got better deal on the black media at tractor supply hopes it helps
That will get the powder coat off for sure. I have been using regular paint remover on all my powder coated items before blasting. Big difference in how fast the PC flies off after that.
If the coating on the swingarm part is powder coat. You will need a lot bigger compressor. You will be better off putting those parts in powder coat stripper
There is a balance you need to find. Too much sand will actually decrease efficiency as the rebounding sand interferes with the new sand. Try a lower pressure and see if it cuts better.
After you change the siphon tube and still its not working, it doesn't mean that your sand is the problem. You must change your gun nozzle. Bigger hole nozzle fix that problem easily.
How frustrating to get a unit that doesn't work as advertised. I use a coarse crushed glass in my home built blaster that works great.Powdercoat is much like the gloves in the box. It is like trying to cut a inner tube with a 2x4, LOL.
I'm having same issues... Made same pipe outta steel. Still didn't work. Made a gravity feed system with meter valve.. Still not working. Thinking about an air injection type thing. Frustrating me like crazy. More experimenting...
Thanks for showing us your new pick up pipe ,i discarded mine and made an adapter at btm of hopper so it was gravity fed ,well it stops tarts farts and is useless so im gonna copy your idea ,Greetings from Wales UK ,if you've time check out my diverse channel ,cheers Ant. ps ive subd you.
Kevin, looks to me like the media isn't flowing freely. Somehow, something is holding back the sand. Just my opinion, but an Uncle had a blaster and he used walnut shells, different grades of sand and man made media for thin metals and they all cut better than what you're showing. I know you'll get it, it just takes time to figure out where the bottleneck is.
I also think your choice of media may play a bigger part. If you're using 2000 grit sandpaper on a car, you'll work harder and longer, than if you're using 80 grit.
Round parts sand blast very hard because they are round and the media hits it and goes around it just like if you put it in a wind tunnel, very different then flat stock,plus powder coating is super hard, better to send it out to a chemical stripper, the best improvement i found for upgrades on a small blaster is to get ridof the pickup tube all togeather and set up a shipon tube with metering valve, you can make your own outof pluming t fittings and a ball valve, no reason to buy them pricey ones on ebay, this allows you to turn your pressure down from 100 to 45 psi, saves on media , does not shatter your media material so much and you canrun it on 3 cups of media and not have to fill your unit up with 40 lbs, makes for quick change over to different grades of media sand, lots of vids out there on making your own metering vales,well you spent this much money for what you got now you might as well take it to the next level because your suck with it now, and get a dust deupty cyclone or a chinise one they work just as good and they cost only 20.00, or you will keep clogging your shop vac up all the time, hope this helps, i used to blast for a living at a areo space company, now retired.
terrible....air jet needs to be drilled out and use bigger(much bigger) nozzle. my hf cab is 10X better than that. also switch to crushed glass($8/50lb northern tool)

good glad it worked out for you.
Powder coating is tough stuff when it adheres properly but I have seen it come off in sheets. Thank you and take care... Paul.
Submerge those powder coated parts in regular paint remover for about 4 hours, rinse with mineral spirits and then blast. Comes right off.
Thank you for the info.

Did anyone ever instruct you an the use of machinery and safety?
Sorry I don't think so thanks for the comment.

@@WPXTacoMan477 Thank you so much for that tip. I have several pieces that this will work great on.
Strong's Adventures yeah no problem Man. Just wear proper ppe and DO NOT use in a non WELL ventilated area
dip the end of the tubing in a coffee cup full of boiling water to soften the tube and it stretched nice
Thanks for the info.
This actually worked :)
Thank you so much for the comment glad to help.
There is way to much media in your cabinet. If you use less it will perform better. We have a video on the channel about how much media to put in.
Thanks for the info send me the link.
So one hole in each pipe? Or two?
One hole thanks for the comment.
Good stuff man
Thanks Michael

Are you going to use plastic pipe?

The hole drilled between the two, is there to facilitate movement of the blast media, otherwise it will create too much suction and pulse.

FYI "Black Diamond" coarse & fine media on shelf @ TSC (Tractor Supply Co.) around $7 (50lbs)
Hey buddy, wich pressure had you useg on this set?
100 psi
@Kevin Robinson I've made exactly like yours but mine still doesn't suck the media 🥲🥲🥲
Well you got it working for somethings. Thank you for sharing!
Black Diamond is to me the best media to use!!!
Thanks for watching black diamond is working great.
We used to send out powder coated parts to have it burned off. We sand blasted them when we got them back to clean them up.
Quick comment from one-time machinist: Buy (or make yourself) a couple of V-blocks. Hardwood is good emough.
Thanks
V-blocks? For sitting stuff on?

What compressor and water setup do you use
I use a kobalt compressor.
Where did you get the black beauty sand media? Thanks again.
Rural King he said, but I think tractor supply has it also.
B-Rad Wilson thank you. We don’t have Rural King but I will check our Tractor Supply. Thanks again
Royal king
Tractor supply has it picked up bag and a bucket of glass media also harbor freight carry’s meds as well got better deal on the black media at tractor supply hopes it helps
Swimming pool filter sand works well. It is dry and pre-screened and costs $8 for a 50 pound bag at the pool supply store.
good to know thanks
No Kevin not good information ! Dont use normal sand, this contains high % silica which causes a lot of lung problems!
@@The_fappening
Phooey. I could see if you do this every day, but incidental use with a respirator or in a blasting cabinet is harmless.
Black blast blasting media is 8$ per 50lb bag at Menards
100 grit aluminum oxide blast media is recommended for powder coat removal.
That will get the powder coat off for sure. I have been using regular paint remover on all my powder coated items before blasting. Big difference in how fast the PC flies off after that.
If the coating on the swingarm part is powder coat. You will need a lot bigger compressor. You will be better off putting those parts in powder coat stripper

After you change the siphon tube and still its not working, it doesn't mean that your sand is the problem. You must change your gun nozzle. Bigger hole nozzle fix that problem easily.
Thank you for the info Hobbyist mind.
Why does it have to be 2 bits of pipe instead of one pipe
One is for air and one is for sand thank you for the comment hsv648.

You will get it figured out Greg thanks for the comment just take your time.
@@Robinson-Homestead turns out the gun that came with the unit is dodgy... Go figure.
Changed hand piece over my cheap arsed one and it works
