This week I am showing you how I machine a new prototype sand blasting / wet blasting nozzle. This new nozzle should allow me to reduce my part cleaning times.

[@tctime]

Nice design Venturi would be.proud.

[@yordan.venchev]

Hi, congratulations on the design and craftsmanship. Is it possible to share what fittings you use for the nozzle. Thanks in advance!

[@ArnoldsDesign]

Thank you The fittings are standard barbed hose fittings and jets I got from McMaster Carr. My newer design doesn't use these fitting though.

[@KW-ei3pi]

@@ArnoldsDesign I would like to see an in depth video on nozzle size and jet size for both dry and wet blasting and how that affects the performance. Thank you

[@kmcwhq]

New camera? The video quality seems improved. I bought my -second- bottle of Molly-dee last summer. There's still a little in the -first- bottle I bought back in the early 1990's??. I'm 58 yrs old.......I think it will be the last bottle I need to purchase. lol. Once again, you have a knack for picking great music for your videos.

[@ArnoldsDesign]

Same camera and setting. After editing, I am just processing it at a much higher bitrate. I'm glad you noticed. That bottle of moly I think I've had since 2001. It's like anti-seize. The bottle never runs out. The best tapping fluid I've used was some blue stuff from Valenite years ago, ValTap, I think? I used it in some other shop, but never found it for sale anywhere. The old Magic tap with trichloroethane 1,1,1, was great too.

[@kmcwhq]

Yes, old Magic Tap was good stuff. Also years ago, I had some really dark thick stuff called Honey Kut. It was AMAZING with drilling steel, but a few days later, the chips and drill press table were all brown rust.

[@4speed3pedals]

Very nice. I wonder if a 45 degree air inlet fitting might work to allow more movement with the blast gun. This would place both hoses in near alignment. Do you think you will ever post plans for a wet blast cabinet or a list of what's needed?

[@ArnoldsDesign]

I have a long sweep 90° barbed air fitting that I tried to make lines parallel, but I've found that it interferes with the back of my hand while blasting, so I ended up rotating it to one side or the other depending on which hand I'm blasting with. I found a straight fitting is the easiest for me. I have considered the 45° attachment, but haven't tried it yet. As far as plans go, I'm still working on them, but they are a ways off.

[@4speed3pedals]

Thank you for the update.

[@scottaero]

very nice, let me know when they are ready to go to work

[@victoradriansyah]

Hi there are the wet blasting uses slirry pump? If so would you please gave what the pump specification, and the compresor psi and cfm that you uses? Thx in advance

[@wxfield]

I loved the tap on top of larger NPT tap @ 4:00. I'm not the only person who does this!! I will get leered-n-jeered at when I do this in my shop.

[@ArnoldsDesign]

When they leer and jeer, you can tell them a lot of machinists do it. A point is a point I guess. I've seen a few guys using them as center punches too and who knows what else. I have a ground center pin in my box somewhere, but it's handy just to grab a tap on the shelf next to me.

[@wxfield]

The 'boss' is always questioned as to his technique in the shop it seems. Wait until you have employees..it's coming. My employees were gobsmacked last week when I made a rotary welding table in less than 5 minutes with an old rotary table, a Ryobi cordless drill and a Kant clamp to "precisely" dial-in the trigger speed. Cringe-worthy, but it worked. Would love to understand how much airflow you had going through the new gun..looked massive!! Impressive results with it however. Really cuts down on time in the cabinet I bet.

[@ArnoldsDesign]

Sounds like a good idea actually, with the drill powered rotary welding table. I might try that sometime. I don't know about the air flow. I haven't bought an air flow meter yet, but am planning too. It doesn't seem like my compressor is running more than usual,but the new nozzle is saving me quite a bit of processing time.

[@wxfield]

Meh..it worked and we got the job done quickly. I have tasked someone with building a more permanent table for welding, but it's taken them a week to put a plan together so I may just take them to a salvage yard near us and hand-hold them thru making one next week. Getting customer work done was always the priority when I worked in my Dad's shop as a kid. Engineers today really don't have a lot of 'get-it-done' experience or attitude. At times, it seems like I'm the old Sergeant breaking in the new troops telling them to forget everything they learned in school: kzbin.info/www/bejne/qYWudJpjqst7q68m15s

[@wxfield]

Heh heh. Sounds like you could make another video on how a pitot tube works to measure airflow !! :-)

How big is the compressor that you are using in these videos? What pumps the water??

[@ArnoldsDesign]

I'm using a Polar Air comp that can put out 38cfm at 100 psi, but I don't come close to that usage with my blasters. for the water I am using a slurry pump.

[@simferopolcrimea4328]

Hello Arnold, Many of us would like to know the model of slurry pump you are using and where to buy it. Much thanks.

Not sure of the cfm in the video, but the internal jet is rated 19 cfm at 90 psi. I'm running about 100 here.

@@ArnoldsDesign how big is your air compressor

[@martincadarajian]

Gracias por compartir su conocimiento , me suscribo

[@BigCatMama]

Arnold, I am a uni researcher from the UK, very nice nozzle there. I am working on a particle delivery system for blasting sand/ash into an aerospace system (e.g. jet engine/etc). I am trying to develop a system that is able to control the sand injection flow-rate and the particle velocity (hopefully), I think these are too fast for my application. I am also hoping to control the spray patterns to make sure there are not fully concentrated in the center. From your experience could you advise if I could do it with a stainless steel tube + orifice plate? (To create the suction). I believe I am able to control the system through pressure, flow-rate and orifice/venturi diameter and the convergent/divergent outlet.

[@ArnoldsDesign]

I just saw your question. I know they sell suction particle devices for moving materials. I agree that you would have to experiment with pressure, flows, and orifices. I don't use a venturi tube here. Instead the low pressure is created by the jet itself. I am able to lift crushed glass into the air stream at 20 psi. My spray patterns are fairly uniform.

[@superturkeylegs]

An automated pressure blast system may do the trick. Use an automatic plunger style abrasive metering valve for better control of flow. The guys at 10x Engineered Materials make great blast media, I believe their EpiX product line is slated for more precise surface prep applications. It's affordable, safe, and very efficient. Best of luck!

[@pesnet7]

Thank you in advance.Arnold Design, how have you been? I'm preventing you from bothering him for days, but I have a question: - Do you use filtered sand or aluminum oxide? In his experiences of blasting aluminum parts. If you don't answer, I'll keep the first one. Thank you in advance. Brazil.

[@ArnoldsDesign]

I use fine crushed glass mostly, but aluminum oxide will work. I stay away from sand because of the lung hazards of using free silica.

[@pesnet7]

@@ArnoldsDesign, Thank you for your attention. Have peace and prosperity be in your footsteps.

[@lomsomesGarage]

I really like the wet blasting no dust what type of media we're you using

[@ArnoldsDesign]

I'm using fine crushed glass that I make here from recycled bottles.

[@lomsomesGarage]

I like it I've been using a soda but it sure takes a lot of it so I'm going to try something ealse I have thought about the glass beads

[@ArnoldsDesign]

Glass beads don't cut or clean well, or remove oxide unless you turn the pressure up really high. At those pressures the beads smash on impact with the parts and you end up with crushed glass powder after a few blasting cycles anyway. Buying crushed glass in the first place is much cheaper than buying glass beads, so it is something to consider.

What is the cfm of your compressor?Very nice blasting nozzle.

[@ArnoldsDesign]

Thanks! My compressor's cfm is 38 at 100 psi, but I don't know the nozzle's cfm yet. The compressor doesn't run a lot while using it.

[@privatejoker7162]

How do you agitate the slurry?

[@ArnoldsDesign]

I buy it pre-agitated. The workers at the packing plant verbally abuse the media as it's being bagged, so when the customer gets it, it is thoroughly pissed and ready to go. Really though, I pump water into jets in the slurry basin. This keeps the media in suspension.

is there a recommended or ideal angle for the pressurized air to enter

As straight as possible. I have mine entering from the back, straight through.

[@ke6bnl]

Arnold's Design actually I was referring to the Suction fitting, my mistake

[@ArnoldsDesign]

I don't know if there's an ideal angle. I just made it so it was comfortable to grip. It doesn't affect the mixture or performance that I can tell.

Do you sell these nozzels?

[@ArnoldsDesign]

I don't. This was just a prototype.

[@bradorman1051]

You should make and sell them. Looks like it works great....i'd buy one. I'm converting my cabinet over to a vapor blast/wet blast set-up. But instead of slurry in the bottom of cabinet, I'm draining into a barrel underneath which holds the pump and slurry. Leaves gun then drains into barrel....and repeat. I'll have a couple different barrels with different medias already set up, when I need to switch media I'll just swap out barrels. Hoping it works as well as I plan.

[@ArnoldsDesign]

Sounds like you're off to a good start. One thing about changing out barrels. They will be heavy, especially if you leave the pump in place. Unless you have a pump for each barrel, it might good just to use the one barrel. If you pull the pump each time, the media will still remain at the bottom, so when you go to put the pump back in, the media will not let the pump set on the bottom. If in instead you pump out the slurry mixture first before changing out barrels, you might as well just use one barrel, and change out slurries in it. Would be less work in the end. I've experienced this firsthand.

[@bradorman1051]

@@ArnoldsDesign Planned on having a dedicated barrel and pump for each abrasive and having the barrels on casters so it should be a simple matter of rolling 1 barrel out and rolling another barrel in. What type of pump are you using? Right now I just have a utility pump to keep the slurry moving and the blast nozzle is just using typical syphon feed. I'm trying to figure out the best way to also pump slurry to the gun instead of just syphon feed.

[@ArnoldsDesign]

Brad Orman Casters should help greatly. You could use a trash pump.

[@tlymoto631]
