Butane distillation

I have instructions for extracting pure esential oil from plant material using butane. The problem I have with it is that at the end, the butane is vented. I just don't feel right about venting unburned hydrocarbons into the atmosphere. I've been looking at glass lab equipment (distillation tubes, connectors, etc). I have no background in chemistry, but it seems to me it shouldn't be too difficult to put something together using standard glass lab equipment to capture, distill and reuse the butane. Butane boils at 31 degrees farinhite and is heavier than air. At the end of the process, the oil is scraped from the bottom of a drying dish. Does anyone have any suggestions on how to put something like this together? Thanks

Gas connections

Hey Guys.  I have a laser tag project that I am making. Now I want to put high pressure air recoil on it. With the HPA being in the magazine and the recoil being a blow back valve in the gun. The issue I have ATM is the connection between the gun and the magazine. I basically want it like a butane connection. I can't find anywhere that shows designs or standards for this though. Or anyone who sells these parts. Also I don't want to use a gas magazine as I have custom magazines and guns. Cheers.

Hydrogen torch - anyone made or used one? Answered

I am working on my own "hydrogen batteries" to create a lot of hydrogen when I need it as a replacement for those propane/butane canisters when camping or fishing. Got some simple prototypes working for the gas creation but do struggle a bit with converting some orifices (is that eve a word?) and a torch to work with hydrogen. Not to mention the pressure regulation LOL Biggest problem so far seems to be the flame temperature. The gas is produce at up to 50°C and my current burners all start to glow red hot after just a short amount of time. Where they struggle to braze copper with propane the hydrogen is almost overkill ROFL Must be really close to these yellow acetylen bottles the plumber use. So big questions: Do I really need a different orifice hole and if so bigger or smaller than used for propane/butane? Do I really need a acetylene rated torch or can I just ignore the orange red color of mine when using hydrogen? I don't think it will melt but after a while the heat travels down into the handpiece too...

Fireball Bomb that works like an A bomb

This is an improved version of lemonie's Instructable Big explosion, bang, fireball, so hoorah to him for it. But any way, my idea is that I wanted to control the exact moment it went off, so this brought me to my first idea, just put black powder and a fuse in the lid of a butane can. Well this didn't work, I just got a jet of flame, plenty cool, but no fireball or musroom cloud. I realized I lacked the essential ingrediants of compression and rapid combustion. So I made this. It's literally a firing mortar for the can, the idea is a non-explosive shell (a coffee can filled with cement with a large bean can set inside to make an orofice) filled with an explosive, with the can of butane in the middle, and a cement stepping stone on top. The idea is that the explosive, when detonated, implodes the can, thus pressurizing it, then ignites the butane, thus decompressing it, A.K.A BOOM. The stepping stone by this point would have come of, thus allowing the expanding hot gasses to disperse. For saftey, the entire contraption would be put in hole in the ground, with no green grass growing all around. The reason I haven't tested it is that I had a very close shave with the cops for the butane can incendierary grenade. Disclaimer, I am not liable for what you do with this information, nor am I responsable for any damage to person or property, in other words, it's your problem if you kill your self. If you haven't yet noticed why this works like an A bomb, what in tarnation are you doing on this site? But, for credebility, I'll say. The main method of detonating a fission weapon is the implosion method. Prior to detonation a nuclear weapon consists of one or more pieces of weapon-grade fissionable material which are subcritical in configuration.The implosion method is when one sphere of material is compressed (through an explosion) to make it supercritical, which leads to a chain reaction, which results in the destruction of the atom, leading too duh, a big explosion.

How to make glass adhere to silver ?

I make jewelry and I've managed to fill a copper loop with tainted glass. I hold the copper and glass in the hottest part of the flame of my little butane/propane torch. But when I try to do the same thing with silver wire, the silver melts before the glass does. I guess that is because silver isn't such a good conducter of heat. So I've tried to heat up the entire peace of silver (instead of just the little loop that I'm trying to melt the glass on) , which works a little better. But even if I do get the silver and the glass red hot at the same time without the silver melting together, I can't make the glass adhere to the silver like it did to the copper. Any tips?

Setting up two forges...

Basically I have two ideas, one of which I'm pretty ready to make now and another which will take a little longer to make, one is a tiny forge, like desktop sized, for working at home and the other is a much larger forge for big metalwork projects, thankfully the large one will actually require less parts scavenging as I have plenty of acces to scrap material and there's a brickyard over the wall from us which will do me the necessary materials very cheap, mainly because I did a little forklift driving for them for larger heavyweight loads over three tonnes. That's all well and good a big one I can get my head round easily enough, But. How would I go about making a tiny forge and I mean miniscule, it's main purpose is for heating to cast for my specialist parts I prefer making and the other is for low material single cast jewellry my mum makes (she used to own a jewewllry business and still makes the odd bespoke items. But my main question is how I can build a reliable yet compact forge and furnace, from what I have sitting around I'm sure I can come up with a decent fuel source, ranging from butane torches and stoves, both of which can do propane and I could go to natural gas (we have a special plug out the back for gas barbeques the house had it when we came...) but my other questions are a bit more odd, first of all what would make a great crucible, I need something that'll be fairly invincible to the hardships caused by life, as the other liely user of the forge and furnace is very forgetful and sometimes accident prone. Next up is the housing, would it be feasible to use a single block of thermocrete cast to make the main furnace housing, as in everything is but the fuel and air source holes and the crucible hole would be one block, as it stands that seems like the best way to make it simple and effective, plus it would be pretty airtight where needed. Next question is the fuel and temperatures, I know that butane at full combustion get 1300C and 1000C is a practicable operating temp. for a butane item but what about propane or even natural gas, since it would be very cheap and clean burning... I'm a bit of a noob towards this end of the scale, I can make stuff hot and I can do alot with these things but actual forge and furnace making is a little beyond me on this scale, however I can think of several advantages to my baby furnace, including the practical movement of it, as it could be self contained very easily. The pic was just one of the last pictures that's remotely intersting I uploaded, however it raises it's own points as the jet engine basically welded all it's components forward of the flame together.

What is the optimum amount of rubbing alcohol for explosions?

I am working on a mini-cannon based project. The cannon has a chamber with interior volume of 15.2 cubic inches. For propellant I am using rubbing alcohol (isopropyl alcohol) that is electronically ignited. The barrel on this gun is about 2 feet of 6mm tubing, designed to shoot Airsoft BBs. I was wondering if anyone knows what the ideal amount of rubbing alcohol to use was (I am using 70% alcohol now, but i can get at least 90% at the store). I could also possibly use butane or propane, if that is better. I went on the internet and looked up the stoichiometric ratio for isopropyl alcohol, but that just told me "1mol fuel to 4.5 mol oxygen at 100 percent concentration." I am not mathematically or scientifically capable of turning that bit of info into a usable amount.

So far, we have had significant success with this combination, but are curious if there is a better ratio to use. With our current specs, we are able to shoot a 3 – 4 lb. ball of plaster over 250 yards (this is the carry distance, not the total distance traveled) at a 47 degree angle.

Tinned my soldering iron, now it wont work?

Hi there. I recently read an instructable on here on how to solder (rather, read through several) and all of them mentioned that it was imperative to tin the tip of your soldering iron. So I took out my trusty butane soldering iron, and tinned it with a layer of solder so thin, I can't see a thickness to it, and can only tell it's there because it's shinier than the tip of the soldering iron. My problem, is now the tip doesn't appear to get hot enough to melt solder (?!), as no matter how long I hold it directly on a piece of solder, it never actually seems to melt. I tried brushing the tip with some sandpaper (while cold) and a diamond drill bit (gently! while hot) to try and remove some of the solder from it, but to no avail. I can no longer solder anything. Any suggestions on what I'm doing wrong or how I could fix this? Thanks, Adam

Scrounging Electronic Components

Old PCBs (printed circuit boards) used to be a great source for electronic parts. Especially if you need a power transistor, MOSFET, voltage regulator, big capacitor, or reed relay which is not available locally. It just does not pay to mail order small numbers of parts, so having a grab bag assortment at home is handy. But I have noticed that the some higher-quality PCBs just loaded with cool parts can be hard to scrounge from: 1. They are double-sided, or even multi-layered, with copper plating right through the holes (vias) so it is like pulling teeth, only harder. 2. They use no-lead (RoHS) solder which needs high temperatures to melt 3. They use surface-mount components and good luck removing and using those. I use 15 watt, 40 watt, soldering irons, solder sucker, solder braid, flux, and a soldering gun. And for some items, a small windproof butane "jet engine" lighter as a mini torch to remove multi-pin items. Just heat-sink the legs and bang the hot PCB down to remove lots of solder at once. Of course I use gloves, safety goggles, ventilation, and proper recycling. But the main issue is that it is getting harder to scrounge parts to build up a pile of useful stuff.  What resources do you use?

I was thinking, when you make the furnace(s) you make a cement/ concrete/ fireclay mixture that can withstand the temperature, so shouldn't it be able to withstand the temperature of the aluminum being poured into it also? (and therefor be able to make the mold out of) - I was thinking to use a special type of cement ment for use around a fireplace.

Cylindrical, it is domed at one end t withstand internal pressure, but the other end tapers to a narrow outlet.The idea is that an explosive mixture in the chamber (anything handy, but gasoline/air, ethanol/air and butane/air are the most likely) is ignited by a spark, just like a potato cannon. There is no ammunition, though.The tapered pipe (I hope) concentrates the blast to release a "bullet" of rapidly-moving gases.The whole cannon points down at the ground, the muzzle only a few inches from the ground. The detonation is triggered via a long cable (metres long). The "gas bullet" hits the ground with a large enough force to simulate the step of a human or animal, or the passing of a tyre. This triggers the landmine left months ago under the soil.My idea is, in effect, a low-tech device, capable of being built and repaired by semi-skilled locals, from scavanged materials, in war-torn areas. With a bit of training, a small team could use one to safely pound a mine-field hard enough to trigger the mines and make the area safe to live in. The cannon would be damaged by explosions, but not so badly that it would need repaired after every use, and it could be easily fixed with scrap from the nearest wrecked landrover.Would this work? Or would they need solid ammunition, say lumps of timber or rocks wrapped in rags to make a seal? That would need a staight (not tapered) barrel, but it's the same idea.I don't have the space or equipment to make one myself, and land-mine charities won't tell me how much force is required to trigger a mine, but most of you reading this are in the US, and it seems you have an easier time finding this kind of thing out.Run with the idea, chaps. Build one if you can, and ship it to somebody who needs it, or come up with better plans than my rough idea, and post them to those who need them.

No patent on this one.

can i use hair dryer or toaster nichrome to make a lead forge?

Hello, a brilliant idea(as they often are) crossed my mind this morning which was to build a 3 in one heating machine. 1. a charcoal maker, heats up wood to the point where it converts to charcoal. 2. burner gas generator. the flamable hydrocarbons released from the sun bleached wood (hite and crumbly, i got tonns of it literally, like moled plane wood), to make fire to reuse for a stove or heater, for something i may want to heat at the same time. 3. lead forge , for melting lead to fill my lead electrode molds, so i can electrolyze in sulfuric acid and then sell, or use, as lead dioxide electrodes for chlorate making etc. Now, butane and propane are completely unreasonable sources of heat, and too expensive as well, so i wanted to know, if the nichrome heating element inside a toaster or a hair dryer, could reach temperatures in excess of 330 degrees Celsius? i want to wrap the nichrome wire , around a steel crucible , separated by fiberglass of course to prevent the nichrome actually touchings the steel, so that when i apply power, the wire heats the steel (which will not be exposed to air) with the nichrome, and therefore heats whatever is inside the crucible , however, i want ti to also be able to reach temperatures in excess if 330 degrees Celsius, so that i can also melt lead. is this possible? otherwise, what kind of nichrome can i directly apply to 240v (wall output) assisted by large contacts for obvious reasons to do so. i know for a fact that nichrome drawing 5 watts is capable of melting lead, as i have melted lead before with my battery powers 5 watt soldering iron, which's soldering tip is a hollow piece of metal with nichrome inside. i want to be sure that this machine will work before i go and buy some second hand toaster or hair dryer at the dump shop. so, will it work? Ive seen hair dryer heating element used before to heat sodium hydroxide inside a steel crucible, in a sodium electrolysis cell, and it went over 320 degrees Celsius. i think. but i cant be sure. i still need a second opinion, thanks
