Need a Gas Tank

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?

Regulator for disposable oxygen tanks? Answered

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.

What type of tank should I build? Answered

I am planning to build a ~2:5 scale tank using this video as a guide. I am trying to decide whether to build the base as electric or gas powered like he does in the video. Electric may be less powerful but it is easier to assemble. (for me at least) I may even make an Instructable on it when I get the time. Any suggestions would be welcome. Although I have pretty much settled on a modern M1A1 Abrams-style design for the shell, my mind could be changed.

Removing rust from the inside of a motorcycle gas tank using the electrolysis method? Answered

Which is better for removing rust from the inside of a motorcycle gas tank using the electrolysis method? Steel anode or carbon graphite anode? I have tried both. I like the carbon graphite better.

Pressure Washer? Answered

I would assume it can't be, but it would be really lucky if a pressure washer could fill an air tank to the pressure the washer is rated for.  So can a pressure washer that says 5000 psi really fill a tank to 5000 psi with the right fittings.  It probably won't be breathable or paint ball worthy but is it plausible.

Building a custom shaped Compressed air tank

Hello, am looking into the possibility of building my own paintball markers, and wanted to do a custom way of using the air system, compared to most markers. I was thinking either a square shape, but after finding an article that was talking about water and gases tanks and why they are build cylindrical, i realized that maybe that might not be as easy or practical. another possible idea would be a flask shaped tank, but for the design am looking at it would need special commendations, none the less I wish to see if something like that could be possible.

Spring powered internal air compressor

Hello everyone, I've come here for some help on designing a PVC-based air tank. I'm planning on building a pneumatic cannon that I can charge once and use to fire multiple short bursts of air. To do I decided to have two tanks -one large tank acting as the main tank and a local tank with a much smaller volume fed by the main. My problem is that I want to squeeze out all the air I can from the main tank, and I'm not entirely sure what the best way to do that would be. My current design uses a spring behind a wooden plunger so that as the volume of compressed air drops, the spring can extend and restore the pressure. (Image attached for clarity) Can anyone spot potential problem areas or places that could be improved?

does this works in practical?

Car running without fuel first i will take some water in petrol tank of a car.now i will connect it to a electrolysis box. the electrolysis gets electricity from battery. now 2H2O[water] on electrolysis divides into 2H2 + O2 this in the engine with the help of glow plug combines and gives 2100C -2800C temperature  and water [in gaseous state] with that temp[ car works as in normal case].The water in the exhaust cools down and again goes back to the water tank. By this the cycle continues and car keeps on working. it will be like this, Battery                       Electrolysis box  [water to it comes from water tank ]              2H2,O2                 2H2+02 [in engine]                                                                                                                       2H2O + 2100-2800 Celsius temperature [engine works] water tank please tell me does it really works out or not

Tired of dumping dehumidifier... Float switch, submersible pump, and a timer?

I have a small dehumidifier with a removable tank that has to be emptied far too often.   It has an integrated float switch in the tank that shuts down once full, but if you neglect to dump it, the basement gets way too muggy. I would like to put in a submersible pump (like this) that is activated by a simple mechanical float switch.  Once activated, I only want the pump to run for a set amount of time, in order to keep the pump from pumping all the water out and running the pump dry.  I thought about this timer, which has a minimum interval of one minute.  One to two minutes of pumping would be about right for the tank size, depending on the pump flow rate and where the float switch was set to initiate the pump. I had originally looked at a Kerick Valve float switch, but this will only let enough water drain out to lower the float and close the valve.  This will essentially just trickle out. Any ideas on this? I don't want to drill a hole in the tank and just run a drain tube... though I considered it.  Part of the reason is that I wanted to avoid just letting it trickle out.  And I also felt like I wanted to tinker just a little.  :)

Arc welding : How do I prevent these 'bubbles' from forming? How can I close them without grinding?

I'm self taught, was joining these diesel tanks to make water tanks, so the materials are the same thickness. As has happened many times before with other jobs these 'bubbles' form. It never really bothered me, but it turns out that water will leak out of the flux pool center. After much grinding my teeth and using the angle grinder the job is now complete and watertight. I would really like an experienced welder to give some advice.

Bicycle iPod dock

So here's my idea: I'm restoring an old bike and there's a spot for a fake gas tank to go. I will build this tank, but one side will open up and hold within it an iPod dock. At least, I'd like it to.  I'm thinking of using the pedals as a dynamo crank which would power the iPod and play music through speakers mounted on the handlebars. I've been doing a lot of research and it seems possible, however, I've not done something like this before and I was wondering if anyone would have any pointers on how to make this work well. P.S. A separate USB port would be cool as well, so that a phone could be charged while riding the bike.  Thanks for your suggestions!

Where is the induction kettle or hot water system?

No modern kitchen these days is complete without at least a single induction cooktop.Convient to even place on the table to keep things warm but also nice to have 4 or 6 "hotplates" to cook on that are actually not getting hot at all.When it comes to efficiency induction cooking tops all others as no heat is wasted.Which brings me to the point...A single cooktop goes now often for well under 50 bucks.Although the base might end up slightly higher than a normal kettle I fail to see why we don't have induction kettles in our kitchen.Why wait 12 minutes to have the thing boil if you can do it cheaper and faster?Way more convinient too as there is no pesky contacts and heating elements anymore, no failure due to leaks either...But what really got me wondering is the hot water systems or heating options like prefered in Europe.Here you have a central "boiler" so to say and water circulates through valves into finned radiators, usually located under windows.We have oil filled radiators of this kind as free standing units that are now being phased out because they waste too much energy with their heating elements.Same story for just hot water :(On demand systems are getting more popular now outside Europe but still the common solution is to have a few hundret liters of water in a tank that is kept hot no matter how much of it we use.Be is gas or electric both types have their drawbacks and to get ahead of the corrosion that always kills them we now opt for expensive stainless steel tanks...Using induction it would be very easy to have a fully sealed tank and to actually only heat what needs to be heated without wasting too much energy.The "heating" element could be just a steel plate inside the tank with no connections to the outside.The gap between wall and element doubles to make the water circulate.And changing from a fixed timer to a temperatur control system to turn the induction element on and off is not hard either.Do you have an induction based hot water system, heater or maybe kettle already?Would love to see it...
