Eric Gaudio: is that stick welding? and what sticks did u use
George May: I would have a moisture trap on the inlet, and I would have done all of the
pipework in iron, no plastic apart from the hose. I think I would also have
afew pressure gauges for fine tuning. The unfortunate thing though is
getting a ccompressor big enough to power this thing upto full working
ability is very exspensive... That's where making an air compressor from
too old engines becomes interesting... That's what I'm trying todo first
before building the pott
bill p: Would think it should work for soda too?
ron fox: I dig it , good job
bill p: I think it is a great ideal.
disgustapated: I think you're replying to wrong person. You're agreeing with me but who is
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
Alex Huntzinger: @steven13121512 sorry it took so long to answer it is 3/4" black cast iron
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
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
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)
Alex Huntzinger: @steven13121512 yes it is a little more tricky to tune though
Killingtime__: 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
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
SmokeTwo Oinks: nice,i want to make one.whak kind of welder did you weld that gal-steel
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.
Cert: Building stuff is always in my family gene. My dad is a new york auto technician and taught me everything I need to know about cars. Now I sell car parts online to suppliment my income. So it does help when there's good guidance.
