propane as fuel?

I am designing a top-secret device. However, i need to know whether i can use propane as its fuel source. i need enough thrust to lift a 120-pound weight (54.5 kg) about 3-5 in (roughly 6-11 cm) off the ground for a long time, until i turn it off or run out of fuel. I am wondering if propane is the best option for somebody who can not afford to spend a lot of money on expensive fuels. Also, can it work without any extra propellants, just air?

Propane torch

I've considered several times buying a propane torch to burn weeds in my driveway, or melt ice. The one I'd like to have looks like a cane with a threaded connector on the handle end to attach a propane bottle. They all seem overpriced to me and I've always wondered if I could make one cheaper than I could buy one. I can find the tubing I need but I've never been able to find the rest of the parts.  Any suggestions or would someone like to post an instructable showing how to make one?

Propane flame thrower

    Please read full post before making any comments. First of all yes, I know real flame throwers use napalm and compressed air to operate, but I don't want any crazy range and lethal power. I don't intend on using this thing in combat. I'm thinking something with a 4-5 foot flame, more if possible, (I don't think it would be with propane, but please, correct me if I'm wrong). I don't want a jet flame so I'm assuming I'll need to lower the pressure to get a more "violent" looking flame with the desired ranged. A "gas pump handle" for the flame control (sorry I don't know the proper term for that type of mechanism. it's not really a trigger. A lever valve?), or I might use a solenoid, not sure yet, Whatever would be more effective. Again, please give me any input your may have. The fuel source would be a large propane tank that I will have strapped to my back, I already have a design for that. If that seems too extreme I might do what this guy did and use a small tank with a reservoir, but with two tanks for more fuel. ( https://www.youtube.com/watch?v=ypIGeNdJbJ4 )  I'm undecided on whether I want electric ignition if anyone could give advice on that as well it would be appreciated. Anyone who has made something like this or knows what they are talking about please give me your input. Yes, I know this is a dangerous project and I take full responsibility should anything go wrong.    This is a video showing the flamethrower that in the above video being used. It displays the kind of performance I am looking for, except I don't want it strapped to my wrists. https://www.youtube.com/watch?v=D5_ogU4Jzt4

Propane vs. Charcoal?

I'm going to make the move back to regular ol' charcoal for its sheer cheapness, and my ability to make it hotter than propane. Mainly though i've been running on the last dregs of my propane, and i'm going on-the-cheap and as free of electricity as possible soonish-like. What do you use and why?

Cheap Source Of Propane?

When I got a new can of propane, for my torch, it was $9. At wally world, it was $4. Then, when I went to get a can of cooking stove propane from the camping department (at wal-mart), I notice that the tank was $3. After getting home, I noticed that the threads were exactly the same, and that the torch head would screw onto the neck of the "camp propane" bottle. So, as anyone would do, I fired it up, and it worked! Of course, it would shut off it you tilted it too far, but what the heck! $3 for a can of propane. But then I thought "Why is this so cheap, and why haven't I heard of this before? Is ther something wrong with this? Will I blow myself up?!?!?! Anyway, I'm all for saving $2, or $6 (depending on where I go), so is this actually a reasonable way of saving money?So what I'm asking:-Is this way safe? I haven't fired it up since, in case it did something bad.-Why is it so cheap to but it that way, and so expensive to buy regular tanks?-Has anyone else done this?If anyone can help, it'd be appreciated.

My PROPANE (!) Foundry

Hey, I'm sure you've read some of my other foundry questions and comments, so here's another. I have been using this with charcoal briquettes for quite some time now, and finally built a burner to convert to propane. I made my first melt with it earlier, and I don't think I'll ever switch back, no matter how high propane gets (price). I built a burner according to the instructions here, and it turned out fine, except that the flame won't leave the burner tube completely. It fits pretty well in my helium tank foundry/furnace (a .gif on how I made it is below), heating it up to melting temps on full blast in probably <10 minutes. It is SO much cleaner, easier to make multiple melts( no refilling charcoal), and is alot quicker in starting and finishing a melt (no setting up blowers, positioning charcoal, and that stuff).It was (at first) an easy choice to go with charcoal (cheap, could even be made for free), but after a couple melts, the fun got replaced by work, and I stopped melting metal. I discovered propane, built my burner for $35 total(including regulator) and was up and running within a day. ~$20 for a refill on propane when I run out is COMPLETELY worth it. Sorry if this seems kinda persuasive, but I am trying to help either people on this site, or one of the countless wanderers from Google.Some pictures of my testing (not my burning setup) setup are below.

Replacing a propane stove with a wood stove --HELP NEEDED

I need to remove a propane heating stove and install a woodstove that I already own. I'd like to install the woodstove in the same spot as where the propane stove sat and I'd llke to use the same venting pipe if possible. The problem that I see is that the propane stove uses a 4.5" vent pipe off the back of the stove and it continues to be 4.5" pipe as far up the chimney as I can see (only a foot or two) also, the propane vent pipe is thin, flexible aluminum pipe that goes up the inside of the chimney, while the woodstove connecting pipe is 6". I don't know if the woodstove can be used with 4.5" flex vent pipe from the propane stove or if it needs bigger, steel pipe for wood fires. Does anyone know? Thanks. Peter Norwell, MA

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...

Building a Foundry?

So I've been experimenting with building a mini foundry made out of steel cans. I've experimented with several different fuels, fuel injection systems, oxygen injection systems, crucibles, and different metals. However, the only metal I've ever been able to melt with it is zinc. (if you don't know, zinc doesn't take alot to melt; only about 700F) My target metals are aluminum and copper, but despite over a year of experimenting, I've never been able to melt either. I would like to know what I'm doing wrong, or what I could do better. Here's the rundown of the furnace's construction: The fuel I'm currently using is propane. The foundry isn't big, (you could fit it in a backpack) so I just use propane canisters for torches with a normal output line on the end. The line runs to a small piece of glass laboratory tubing with a tiny nozzle on the end which is about 1 mm in diameter. The propane shoots out as a stream and mixes with air utilizing the venturi effect. The propane mix then shoots into a large metal pipe about 2 cm in diameter. It then bends up at a 90 degree angle and enters the furnace, which is in essence, a steel can with a hole in the bottom. inside this is a steel can cut in half with a thick wire through it to suspend it above the burner.  So what could be improved? When I run it at full blast, the whole furnace glows orange, but no metal melting happens...
