I have a 14000 rainwater tank, and like to find a way go clean the debris from the bottom potentially recycling the disturbed water - so there is minium loss i have a ready supply of compressed air near by.,.,. can any one devise perhaps a venturi device that is easy to build, runs on compressed air and effectively vaccuums the muck from the bottom while recycling the caputred water....

If I were to have 2 seperate buckets, one with ground and the other with something like 9 volts nothing would happen because the 2 bodies of water arn't connected. If I were to join the two bodies of water using a wire would electrolysis take place?

I have recently acquired a 25 litre compressor on which the motor was seized so my plan is to replace the motor and pump with a couple of fridge compressors however the tank is more than 10 years old and although I cannot see any damage is their anyway to check it is safe to pressurize to 8 bar? it has 175PSI stamped on it so I assume its designed with that as the maximum working pressure but I want to know if I can get it checked as I don't want to blow myself and my garage apart if it bursts I'm in the UK

Hey guys, this is my first time on the forum section of the instructables! Not a bad place to be, really. So here's the thing. I have this old scooter that I've had for as long as I can remember. It was the very first thing I rode that was powered by a motor and my father bought it for me so I could get ready for my first motorcycle (Which was sadly stolen about a year ago :/). Last year, my dad went back to our hometown to visit family and he brought it back with him, but there was one problem. We have no gas tank for it. I have NO idea where it could have gone or why it wasn't brought back. Oh well though. I have this scooter, the same as Wesley666 does. I'm having trouble finding the gas tank on my own. Notice that there is a gas tank that I took from a weed eater just to try it out. But I'm not sure it would work out very well. I mean, look at the size comparison between the two? I also want to keep original parts on this nostalgic machine. Sorry if the pictures are oriented weird, but these are taken with my phone.You can see from the thread posted above there is a picture that shows a blurry close up to the gas tank and I can't really tell what it says. "Something EBR Motor". Long story short I need to get that gas tank, maybe even the gas line that comes with it, in order to get this thing working again. Does anyone know of the brand name of the scooter so I could get the original parts I need?

Hi, I have coffee machine with small water tank. i want to put large water tank next to it so i would not need to refill it every time. my problem is that the water tank in the machine is not sealed, so if i put more water with a hose from bigger tank it will spill out.. How can i create bigger water tank next to it so the smaller tank will refill automatically? Thanks,

Some friends and I are looking to make some projects, mainly air powered. We have been looking for an air tank to hold the pressure before we discharge it but have been having problems finding the exact part. I have found lots of the air tanks to fill tires and stuff like that but I need something to hold a good amount of pressure and let it out in one big shot and can be charge with a normal car tire air compressor. -I need to know the exact name this items goes by. (Just "air tank" gives me the tanks for tire inflation) -I need to know a webite or store to purchase them at. (Home Depot or Grainger by any chance?)

Alright fellow instructables, here's the lowdown: I'm currently attempting to build a hand-held flamethrower that you only need one hand to use, sort of like a pistol. However, when I was looking at a diagram for a regular Army flamethrower, I realized something: The fuel tanks on the flamethrower werent pressurized, and the fuel was pushed out using a pressurized tank that was fed into the fuel tanks. Now here's my question: Because I'm just trying to make a little hand-held that I DON'T need to shoot 50 feet, can I skip the pressure tanks and just jump to a commercial fuel source, like one of those miniature camper stove fuel tanks? Thanks Outdoors!

I am creating a custom fish tank stand from 2x4s and sheet wood. I plan to paint it black but I ran into 2 problems when I decided I didn't want the hood that came with the tank. 1) The lighting. I have a pretty good history with LEDs so creating the lighting will not be too hard, only real issue I run into is sealing the lamp. I plan to use an acrylic sheet with holes drilled for the white and blue LEDs. White for day and a row of blue for moonlight on a 3 way rocker. I just dont want water to penetrate the holes from the ports for the light to damage the components. 2) The filter. This is where I am at a loss. I plan on making something similar to this: http://tinyurl.com/fishtankdesign But I have no idea how to an external filter rather than one of the regular table top aquarium ones that would not look very pleasing on a nice stand. Any ideas questions comments or concerns please ask.

Does anyone know how I can get (or make) one of the regulator / valve things that screws on to a disposable oxygen tank? I would use the regulator from a propane torch but it has to have left hand threads. All the ones on Google shopping and Ebay cost like $40 and I realy don't want to pay that much, I'm thinking more like $10 or $15. I could use a Nitrous Oxide dispenser like the ones used for making whipped cream instead if anyone knows how to get or make one for the same price.

Hi Girls n Guys, I moved about 6 months ago from a house that had combi boiler to a house that has a hot water tank and standard boiler, Over this period we are using lots of hot water due to kids baths and bits, draining the tank too quickly, so the tank is in a cupboard just off the landing and was told I can get bigger tanks, the current tank is a 1050x450 and I'm looking at a 1500x450, Question is will I need to re-enforce the floor any more than its current state! Thanks Matt

Ignoring resonance what should the average capacitance of a Tesla coil tank capacitor be? In what appliances can you find large high voltage capacitors, preferably above 10nF? And can you use microwave capacitors in series for a Tesla coil tank capacitor?

My tankit has a mg. and uses no chain peaces. the only exotic peace it uses is a orange gear. like a yellow gear it has the pegs sicking out of it but only has half the pegs. it can be made by cutting off half the pegs if you want. not very power full but that is because i am using a clasic motor. the motor has to pull bach the ram so to much rubberbands and the motor can not pull bach the ram. if made with a beter motor it could be stronger.o and the last picture is of all my knex guns :)

I was looking through the internet, and was linked to this page. There they used a freon can for the foundry shell, but I thought those small helium tanks would work too. I kinda knew that a dremel wouldn't cut through it, but it is just what I put on there. I used Inkscape and GIMP to make it.Also, does anyone know a good source for fire clay? I've heard that masonry supply stores are a good bet. Another thing - does anyone know a good page on a cheap, simple, charcoal foundry? I made a .gif animation describing my ideas, below. In the animation, I meant to put the part about cutting the hole for the blower in the beginning, too (after I cut the top off).

I have been browsing through all the fish tank instructables and I thought that they were rather rubbish to be honest.... I want an instructable to build a decent tank in a rectangle shape with the dimensions of Height: 12" Length: 20" Depth:14" (Dimensions do not have to be followed but appreciated if they are and dimensions do not include lid space) If there is also any specific thicknesses needed for the tank to hold the capicity of water this would greatly appreciated if stated. I would also like the person who choses this project to use links to websites for the materials/tools (preferably English GBP currency) Any links to what types of fish are work well together would also be a bonus. Thanks in advance to anyone who will write the instructrable for this.

I can patch the side leaks on me metal tank easy enough with marine epoxy. but there's no way i can crawl in the tank without destroying the bottom with my weight. i would like to find something i can pour in there that would sink and find the hole and cover it up. wouldn't take much with the water pressing against it. maybe some sort of saw dust? it would eventually sink and find the leak? but it can't rot over time or have bad chemicals in it... or something made of much smaller particles? really needs to be a remedy tested by time, maybe something from our grandfather's day. or, i could make a remote controlled robot with manipulators and a camera! nahhhhhh..... thanks

I have a 50 gallon water tank in the basement and a solar tank on the roof. The roof tank is 35 ft above the basement tank and the top of the basement tank is connected at the bottom of the roof tank with 1/2 inch Pex with valves. Is there a simple way of pumping the basement water to the empty roof tank. Unfortunately I can't use city water pressure to force the basement water up to the roof. I am trying to transfer the basement water to the roof leaving the basement tank empty.

I have a 1550 gallon water holding tank and plumbing in an outshed in Fairbanks, Alaska. The pump and pressure tank are also in the outshed heated with an electric heater. To save energy I'm thinking to install a circulating pump inside the tank that circulates through the plumbing inside the outshed to keep it from freezing but not necessarily to the portion of water pipe going under ground to the crawlspace of the house. It should also have a thermostat to start heating when the temp of the water gets to 32 degrees or so. Is there any such thing and if so, how would it be installed? Thanks!
