where can i get a spray can-like spray nozzle made from metal?

Hi, im currently doing a project which uses a high volume, low pressure water motor and needs to spray a mist, using little pressure. Essentially what im after is something with the same specs as a regular aerosol can spray nozzle, except it needs to be straight, and made of metal, so it wont dissolve in the petroleum oil, or slip . ive tried using a normal spray nozzle but the pressure is too great and no matter how i go about binding the tube to the nozzle it always pops out, either because it grows soft and warps from the petroleum oil in the spray mix, or from the overal lubricating effects. either way, using spray can spray nozzles is bad. For another project ill be doing at the same time, which is for watering my plants, i still also need a straight spray head, prefferbly made of metal, as this one will have a bit more pressure behind it, and i need to be able to absolutely permanently attach the nozzle to a pvc plastic hose. I dont want to vary at all from my design, or compromise with a plastic version. What im after is a straight spray nozzle, aka, not bent, that sprays a mist of roughly more or less the same size and directionality, and angle as a earosol spray canister. for all intents and purposes, my water motor will be putting out perhaps 2/3rds of the pressure of your typical spray can, a normal spray nozzle works fine, so all im after is a metal equivalent, or anything that wont dissolve in petroleum oils, acetone or paint laquer. does anyone know where i can find such a thing? thanks

What is making my sprayer drip?

I've replaced all the O rings, so now the only drip is in the spray.  About 1/3  of the cone of spray just sprays crazy and dribbles from the hole in the top  of the domed piece that screws on.  The hole looks round to me.  I can't tell if the inside of the dome is uneven.... it's pretty small and dark in there.  I've cleaned it with Barkeeper's Friend on a Q-tip, but there is still some staining.  If the problem is inside, how would I smooth it out? If the problem is in the male part,  what should I be looking for that might cause this?

0.3mm nozzle printing speeds?

I am currently finetuning my homemade hotend and was wondering what you guys have in the speed settings for 0.3mm nozzles printing ABS? I started with the aim of reaching 120mm/s but after some hours of finetuning I am currently trying to breach the 200mm/s barrier. As I am only using a very old Mendel Prusa I am actually quite happy that I got that far. What speeds are possible with the current printer models? (not the statements on the website, real life)

Clear Spray Nozzle? Answered

You can turn the can upside down and clear the nozzle before it gets clogged. That way it doesn't get clogged, and you don't have the problem.

What is this tool?

Today, I had a clear out of the workshop (Okay, shed) and found this peculiar tool. It's being lingering around for years now, and I've never been able to figure out exactly what it is and where it came from. The orange thing pushes down and locks, and when it is at the bottom a tiny metal rod appears and dissapears again at the end of the white nozzle. It holds in place until you press the orange button, at which point it fires the orange thing out at a fairly high speed, and it stops when it reaches the end of the blue channel. If you cover over the nozzle, it fires very slowly, so it probably sucks air from there. Does anybody know what this tool is?

Vortex tube should have a supersonic nozzle for efficiency; a simple drilled hole will not allow supersonic flow, right?

Scientific American had an article on supersonic nozzles in Amateur Scientist.  The nozzle needs to first narrow and then widen, so that maximum velocity is reached by the expanding air. The Hilsch tube seems to be very primitive because of details like the primitive nozzle.  Perhaps, the Hilsch tube was designed to have too much friction.  Perhaps, the tube was built to be sure it was inefficient and not very useful.  The tube can only violate the Second Law if it is built with a minimum of friction losses.

Cheap External Mix Snow Machine

*EDIT* IT WORKS!!! Hi everyone, this is a simple DIY snow machine. It utilizes external mixing which not only increases the production but also eliminates the risk of water backing down the air line and vise versa. I will not be making an instructable but possibly a video displaying its qualities. It only needs an air compressor with the standard quick connect end and a regular garden hose. It works and I may be selling a few on ebay for ~$75 each and will include a professional looking instruction manual. This produces a very large mist and i have yet to measure its snow making capabilities. I expect it to make about 2" per hour over a 200 square foot area. Please comment and rate!!

License question... Answered

I am currently in the finnishing stages of a new aluminium print nozzle for 3D printers. Of course I would like to share my project here soon but I also would like to see if it has any commercial value. I would only be able to make a very small amount of them each month and the hours I have to spend in my workshop for it would not be justified by any price. So if someone would have an interest to mass produce this nozzle what would be the correct type of license to choose from when publishing the Instructable?

Need help with Aeroponics misting system any ideas? Answered

I've been struggling to build an aeroponics system and the only problem I have right now is the misting system. I purchased some misting nozzles off amazon that I inserted into some vinyl tubing and sealed with a silicon sealant. I used a small DC 6V pump powered by my Arduino to pump the water to the nozzles. Now the little pump couldn't provide enough pressure to create a mist of water (I think its pump rate was something like 15GPH) it came out with some of the water leaking while a steady stream sprayed in four directions. So my question to the instructables community is was it my little pumps fault or did I get ripped off buying bad nozzles? What pump should I buy that will pump enough pressure to create a mist? here are the nozzles I bought and here's the pump I bought: http://www.amazon.com/gp/product/B004HHW0FU/ref=oh_details_o01_s00_i00    http://www.amazon.com/gp/product/B004U3MRIG/ref=oh_details_o02_s00_i00     One more thing, I was thinking of a misting system which I'm unsure will work. I got the idea driving behind a truck after the rain when the road was wet. The wheels were spraying a mist behind them as they drove over the wet road. Could I simulate that effect at all with an electric motor and a small wheel?

hobby rocket using rocket candy

Today I tested a homemade rocket engine made with r-candy and clay catlitter (for the nozzle and plug). The nozzle was made from clay catlitter with a tapered hole I used about twenty grams of r-candy then l put a thin plug of catlitter. I had placed the rocket upside down on a bamboo rod clamped to a table with a scale under the engine but when I ignited it the sound was so great that I had to step back and could not get a reading but from the looks and sound of it the small 500 gram scale would be maxed out then at the end of the 3-5 second burn the thin plug at the end popped off shooting the engine up in the air this was becouse the core was not drilled all the way to the end so when the burn was near an end it found it easier to escape threw  the thin plug then the narrow nozzle.

MIG Soldering Iron Concept

The plan is to modify a existing soldering iron remove the tip have a small nozzle at the front (made of a thick disk of metal, drilled with a normal bit until a small hole is poked, thus making a cone nozzle)(thinner than what i put in the picture, because the taper should be 45 degrees) the area where the tip is screwed in to will be where the solder liquidfies a hole will be drilled above that for a flexible copper tube to guide solder in the tube will be heat sinked so the solder only liquidfies when it is near the chamber the solder will be feed with some sort of unreeling mechanism or something that is controlled by a button the feed will be guided to the copper tube via another sort of tubing the pressure of adding solder will force the liquid solder out the nozzle the goal is to have a tiny drop of liquid solder, small enough for average through hole soldering, come out with a press of a button. flux should be applied before. does anybody see anything wrong that could happen with my concept? does anybody have other ideas and suggestions? had this been thought of before?

Color changing LED faucet?

I'm looking to make one of those faucets that changes color with the temperature of the water coming out of it. I already have a preliminary circuit using a thermistor, an LM311 comparator and a couple LED's. Just wondering if anyone had any tips of how to refine or whatever. Also hitting a roadblock on how to power this, as I want to make it entirely analog (no microcontrollers, just op amps and the like) and I want it to be fitted to an actual faucet nozzle. If it is fitted to a nozzle, space is very limited and batteries are really not desired. I was thinking along the lines of a mini waterwheel or something that uses kinetic energy from the water.

homemade paint gun/ airbrush

Ok well me and a friend of mine have been experimenting with making our own paint gun. we are doing for two reasons. well we want to airbrush some things but we don't have one adn we don't have much money, and we need something to do so it occupies time. we have gone throught many trials and errors and quite a few have failed. we now have one that works acually pretty well. it composes of blowgun attached to an aircompresser, there is a "t" fitting at the other end of the blowgun, at one part of the "t" fitting is a little attachment that goes to a small water bottle, and at part of the water bottle is a little nozzle(nozzle2). than at the other part of the "t" fitting is another nozzle (nozzle1). those nozzles are really close to each other. you put the paint in the water bottle and supply air to it than it paints(sometimes) i was just wondering if anyone knew how to make it better or had another idea for a paint gun? any comment that is related to the topic is welcome and thanks for any feedback. i am sorry if that is confusing.

Coanda effect in conjuction with Venturi effect !?

I am still working on my project to create relatively accurate model of a Repulsine. No, I am not one of those free energy nut balls, just curious in old tech ;) As part of my research I came across some statements in regards to lost pieces of the Repulsine. The last remaining model still exists in Austria but noone seems to have to clue what the missing parts looked like. I think the missing parts are a system of nozzles, diverters and a secondary hull - forming a similar system like the Coanda plane engine. There are lots of people still out there tinkering with Coanda lifting devices and trying to get them working. Is there anyone here doing it ??? Would like to exchange some knowledge, tipps, designs and so on. Short term goal is to make working Coand engine with enough thrust / lift to be used at a later stage for a working Coanda plane model. Long term goal to modify it all to incorporate into the Repulsine.
