Homemade Sandblaster And How To Build




What do you think about this video?

GHOSTGXZ: In case you didnt know using actual sand can cause you to get silicosis if you inhale the dust. What most sandblasters use is aluminum oxide which is what is used for sandpaper 

disgustapated: I think you're replying to wrong person. You're agreeing with me but who is Pat??

Alex Huntzinger: no i didnt use any thing for rust you should use a air/water/oil seprator the hole in the tank is 3/4 of an inch use black cast iron pipe with yellow gas line thred tape ball valves are a lot of money like 15 20 dollars a pic the gate valves are 4 dollars a pic no i did not put a dead mans valve on it i didnt have a lot of money to spend i cant make a vid of me useing it because i dont have an air compressor bigenf to power the sand blaster and i moved to an apt and my garage does not have power

Ichiban Moto: Nice set up ! Wish I saw this before making mine!

John Doc.: I've just started making a similar pot using the same size tank. Instead of welding the pipe connections, I've run a single length of pipe right through, with about 3"protruding top and bottom. It has holes drilled in it just inside the tank at either end (for Air and Grit flow). It's bonded in place with epoxy resin, injected through the filling hole. Just need a filler tube and cap now...

isaiah the man: my sandblaster is pretty similar

disgustapated: Just for the record nobody said anything about Chinese products... He compared his home made equipment ( which is fine,but not for untested pressure vessels ) to other expensive equipment.

Alex Huntzinger: pis lets say 45-50 psi at 4-5 cfm would work but not as fast but have a small nozzle on exit the blasting tube work with what you have i do it all the time keep me up to date

Aaron s t: I have made 4 pressure pots using 30 LBS propane tanks and TWO using 100Lbs propane tanks. Yes it is making a pressure bomb. If your not an idiot, and do it properly you will never blow yourself up. Disgustapated, you should try and make one. maybe you wont be good at welding and natural selection may sort you out :) Trying this is not for the weak of heart, or the unsure of skill. Period. If this scares you, easy dont try it. trust some outfit in china do to a safe job. lulz

byronmill: All you certified welder pressure vessel building know it all PITA dudes need to get real. He is not reusing the tank to store propane, it will likely never see more than 100 PSI of COMPRESSED AIR!! How could this be considered a bomb? What serious thing is going to happen if his weld fails? Your imagination is running wild on you. For goodness sakes, he has vinyl hoses with barb fitting and hose clamps exposed to the same pressure. Imagine the nightmare if one of those fittings failed!! sarcasm

Roy Lewis: Do you have a video of you using this sandblaster? Thanks for posting this one. RL

Alex Huntzinger: @steven13121512 sorry it took so long to answer it is 3/4" black cast iron pipe

disgustapated: You're an idiot...

A1986Ge1995: Do you know what are you talking about??

Alex Huntzinger: CFM means Cubic Feet per Minute to put it in a pic i have a little craftsman air compressor it is 2hp it puts out 90psi at 4cfm the tank is 3gal i hope this helps a little

Jared Chewitt: hey could you give me a list of the parts you used and some guide lines for building?

Steven Singh: could you put soda in the tank? and will it perform well you think?

Alex Huntzinger: @disgustapated im really not you should do some research before you start criticizing on people it's not a pressure bomb I'm a certified welder I know how to weld aka good heat transfer I would not recommend somebody that's just starting out welding to do this

Alex Huntzinger: It's not really based on horsepower it's based on CfM cubic feet per minute 90psi at 4 or 5 cfm should be good enouh so basically if you go to the store and buy an air compressor make sure the compressor pump itself says 90 PSI at 5 CSM or higher the higher the better but the horsepower rating should be around 2 horsepower all the way up to 10 horsepower electric or gas

Alex Huntzinger: yes it does thank you you have to save money now a days lol

A1986Ge1995: You could try and put a small valve under the tank were the sand comes in the air stream it will make it a lot easier to tune

MrHuskerOne: Id like to see it working

Aaron s t: my homemade pressure pots are the same as those fancy 5 grand pressure pots. i used their schematics and plans -_-

John Doc.: Meant to ask Alex, do you bother with a Ceramic nozzle? If not, what did you use? Got my filler pipe and cap today, just finished welding it on, along with some legs to lift the pot clear of the floor. Need to knock-up a simple little cabinet now. I'm planning to make it foot controlled, by connecting a pedal to the lever ball-valve, and fitting a return (closing) spring.

Alex Huntzinger: @steven13121512 yes it is a little more tricky to tune though

killingtimes1: just wondering if you have used a soda blaster with an air compressor at 5cfm and how it worked out? I am looking to get one, but most soda blasters state they require at least 7cfm and compressors >6.5cfm start running 450-500 up. based on my researching lately, one could run a 7-8cfm soda blaster on a smaller air compressor say 5cfm, but would have to wait a long periods for the tank to fill back up. What's your take on using a larger cfm blaster on a close but still less cfm compressor ?

Alex Huntzinger: thanks for watching my video thanks for the concern but i went to school for welding and i can weld vary well not trying to be an ass

thinkpad411: The pressure pot is dealing with low pressure usually... just enough pressure to inject the sand into the air stream.

Aaron s t: @disgustapated heh. your funny. i dont think anyone who cant weld, or think, would try something like this. like i said ive made 7 and theyre safe. i still use one from 20 years ago. stay safe kids, if your a moron, just buy a new one. if you have a few active brain cells and a little know how, you can do this safely. and im very impressed you can weld. i do full auto restorations. if your afriad to, dont try it

disgustapated: Yes I do...This is a pressure vessel, of which somebody welded on...welds create a HAZ -"heat affected zone", this could be a weak point if the weld wasn't done right, or stress relieved and i doubt that this was hydro tested either. What do think will happen when 100 psi escapes in an instant?? Even though it has a small amount of volume,it still has a tremendous amount of energy . Google pressure vessel explosions...see for yourself.

Alex Huntzinger: view a soda blaster as a fire extinguisher every thing is under pressure there is a tube that gos to the bottom of it to pick up soda comes out at vary high speeds cfm the more cfm something has the longer you can use the blaster 90 psi and up and like you said 5-7 cfm is more than enough to work but if you have a smaller air compressor you can still use it but the blasting tube on exit will have to be smaller to work like its sopost to 4 to 5 cfm is good at 90 psi but u can work at much lower

disgustapated: No,they aren't "as good", not in this situation...I hope you don't kill yourself or someone else...

thecuddaking: Sure beats the $100 harbor freight setup

holyluke: thought ur name was disgustedpat... my bad??

Dunia Bengkel: great work man.. i don't understand the CFM deal.. here they sell compressor using HP, any idea how to confert HP to CFM? or it just 2 different think ;)

disgustapated: You have made a bomb...good job !!

thinkpad411: HP affects how fast the compressor itself will run and therefore how much volume it can supply per minute. Low revs with large displacement will generate the same as high revs with small displacement, and the compressor will last longer without a rebuild. An engine and air compressor are the same thing, just that each are purpose built. You can convert any gas engine to an air compressor with some check valves and disabling the exhaust valve/valves.

SmokeTwo Oinks: nice,i want to make one.whak kind of welder did you weld that gal-steel with?

holyluke: btw... has nothing to do with heat transfer... what pat is talking about is how when the weld metal is brought to its UCT (upper critical temperature) and then slowly cooled it creates a HAZ heat affected zone around the weld that becomes hardened or "tempered" and that is the area the will get you, it will always break beside the weld assuming your welds are good. this is why in industry we send our vessels to be annealed in an oven wich returns the HAZ to its parent metal state.

Chris T: Be very careful welding galvanized anything, you can get zinc poisoning from the fumes that is left out, I know from experience from welding galvanized for a living. We had special whips that had vacuums on them to pull the fumes away to a filter system. Some guys got very sick when they decided not to use the vacuum. Your best to stick with black pipe. It is your life and have been warned.

Alex Huntzinger: @A1986Ge1995 i did put one on it like a week after i posted the video and yes i do know what im talking about

Steven Singh: hey alex what is the thread and size that goes into the propane tank. Thanks

ilovemachy: How much psi do u use for a small project

autofabwerks: Pipe in the forehead--lmao-- no jb weld folks--; dont know how to weld dont attempt. iam a master welder- and totally agree- project is cool. Two thumbs up. No pipe in the face. Lol

gumpydoood: Welding galvanized pipe produces a toxic gas. Be careful.

keith hendrick: Hey!!!!! another video showed how make sure tank is empty. opening the valve does not empty tank you must press the internal release with screw driver or the like. This may have saved my life

jdubin660: i would like to see it work make a videos showing it working please

CoolasIce2: Nice project, but I'd be a lil skeptical of the welds between the iron pipe and sheet metal tank. At 120 psi the pipes could break off and be dangerous.

Mario Jose Gonzalez: A real life MacGyver!!! Awesome dude! I'm building one myself!! Thanks for sharing the brains man! PEACE!!!!!

Scott Jones: My kind of guy,I make all of my own stuff too...looks crude but I save lots of money and the results are the same as expensive stuff.

Schools: Learn how to get phlebotomy training in California! The job pays decent money for the amount of schools needed to graduate.
