Hey guys n gals, I am in Cape Verde, and they don't sell Butane torches here - neither a hose torch or ones for a disposable bottle (my previous one died, but they don't sell refill bottles anyway). What are your thoughts on making one from scratch to attach to my butane bottle? It is currently fitted with a standard low pressure regulator (camping gas). I have a bronze ball gate valve and copper tubing, and the means to fabricate stuff. What measures could I take to prevent the flame backing up the tube? Or would the regulator prevent that? If there is something I am missing then please explain what and give suggestions to overcoming the problem. Thanks.

Part of getting the gas to burn is the proper fuel/air ratio

and getting that is a proper Venturi effect that blends the air and fuel.

gonna be a lot of trial and error to get it right. Plus if you look at the tips of most torches, it’s not usually a straight tube...

so while getting the fuel to burn is not that difficult,  getting to burn right is the hard part.

Yea, I have seen that the tips of most torches have holes in them, I assume for air mixing. I plan to have a 80 degree bend or so for ergonomics. I'll take pics when I start the project.

So my proposed idea is ok then? I guessed it might be, but wanted to check.

In case you didn't get the joke, your idea is very bad.

Hillbilly engineering a butane torch is a very good way to blow yourself up and/or burn your boat to the waterline.

Don't do it.

Thanks for the advice. But that is why I was looking for people with knowledge. Please explain why. I am not a hillbilly engineer, I have experience with metal working. But I need to know what the issues I am facing are.

If there are specialist parts I need I may be able to get them locally ie. parts for a stove etc. I am willing to accept that it might not be possible, but I want details to be able to make that decision myself. So if it is beyond your expertise please don;t bother commenting. Thanks

No, I didn't realise you were joking, because I asked that only people that knew what they were talking about comment. ;)

If you're of the opinion that only shop brough items are any good, you won't last long if you ever go cruising in third world countries. If I wanted to just stick a pipe on the end of the hose and call it good, I wouldn't be here asking questions.

Unless you can explain why, then your opinion is just that, and not what I am looking for.

Honestly, I left Cruisers Forum partly because I am sick of people who don't have any knowledge on the subject in question offering "advice". Next person that does it gets blocked. If you can't be useful then stop wasting my time.

I've cruised a lot in 3rd world countries but sometimes the answer is you can't get it here and wait until the next country. Find a welder with an oxy/acetlene torch and use a low flame if you can get whatever off the boat you need to heat up. Use a soldering iron if it's a smaller fastener that needs heating. Borrow a backpackers little gas stove. 

If you come asking for advice and people are genuinely concerned about you not blowing yourself up, don't be an asshole either.

And the reason I also don’t patronize CF is that it’s a shitshow, I agree.The nice thing about SA is that the morons are generally sent away. If you want validation for a bad idea, here is not the place. And yours is a bad idea, especially since you have to ask an Internet forum how to do it. Welding goes on in the 3d world, they buy their stuff somewhere

Your comment seems reasonable, but what I am hearing is that people don't have the skills to carry out this project themselves so therefore neither do I. Generally, that may not be an unreasonable assumption, but they know nothing about me. I have lived on a ship for most of my adult life, and worked in marine salvage and boatbuilding, in countries where there are not the resources to do things "properly", which requires engineering and fabrication know-how. So please do not doubt my fabrication skills. The issue is that I do not have experience with this particular job. I know how to do research, but I also value first-hand knowledge. 

As for these other commenters - yes, I get it, mummy said don't play with fire. Kindly take your gold star and gtfo. :)

Unfortunately those ideas are at two different extremes from what I require, which is paint striping and loosening rust from stuck bolts - a soldering iron would not be hot enough, and oxy-acetylene would be over-kill. Thanks for the input though, I guess I should have made my intended use clearer. I live on a steel hulled ship btw, just in case you were worried I was going to use it to strip paint from a plastic boat :P

Yes, I tried very hard to be polite, but the comments assumed that I was unskilled, meanwhile I have probably 10x more skill and sail miles than 90% of the people here. But I try to be humble, though it seems that I am going to face exactly the same bigotry here as I did on CF - I am 40 years old, and not 60, and therefore my experience is less valuable then their ignorance. If chinese children can build these torches, so can I. What I am asking for is what I need to consider to do so safely. If people don't know, fine, but that doesn't give them the right to leave a derisive comment.

 

With all due respect, I earned the right to be confident in my skills, so I don't feel the need to allow other people to talk down to me. I appreciate the fact that I am able to speak my mind here though, as unpopular as that may be.

1. You can use oxy-acetylene to heat stuck bolts, without cutting or melting them. Heat them orange-hot, then quench them with a shot of water. Usually breaks them loose. You probably already know this.

2. I have tried this process with a propane cylinder without luck. Cannot heat the bolts to orange, just to frustration.

3. There are gasoline and kerosene fueled blowtorches. They are sold as antiques in the US, but you might find them where you are.

SA used to have a fun hazing ritual for noobs. It involved the old timers insulting the noobs. Noobs with thin skin sulked off.  Those with knowledge and skills stayed. It resulted in an ecological/intellectual space populated with smart people who demonstrated their knowledge via the content of their answers, not by citing how far they had sailed or what boat they owned. Acquiring wisdom is a subtle process.

Anyway, I guess I should have also pointed out that this is not for welding, but paint striping and loosening rust. I do not have access to a machine shop, but  I can do some pretty good fabrication with the tools I have. I am not seeking validation for a bad idea, I want to know what is required to do this properly, and then I will make my own judgements as to whether or not I can achieve that with the tools and supplies that are available to me.

I found that my little butane torch was enough for these jobs, but it died to rust, as I mentioned previously, plus refill bottles for it aren't available. I agree that oxy-acetylene would be easier, but I have manage with a simple butane torch before, and I don;t have any jobs that would require anything stronger, and I would rather avoid paying someone else if I don't have to. Attached is what I had, I don't need any more functionality than that.

It may well be the case that I must just buy what I need from Aliexpress and put up with the six week wait, but if I can fabricate this safely then I would rather do that. I have yet to hear a good reason why it is not possible to do so.

I can't speak to fabricating it.

I will say that I just purchased a similar butane torch from Amazon for modest bucks. They also carry the refill cylinders in bulk, and can ship them to you unless you live in California-stan (a well-intentioned poorly-considered law complicated butane fuel purchase recently since potheads had been blowing themselves up while extracting cannabis oils). Hopefully your current location is a little more intelligent with fuel restrictions -- these little butane torches are exceptionally handy when I don't want to run an extension cord or drag out the oxy/acetylene kit.

Here there is no problem buying butane/propane, except the refill canisters for the standard disposable hand held torches. So i need a torch that connects to a hose. Most places do not ship to Cape Verde at all, and if they do the prices are ridiculous. The only place that does reasonable shipping rates is China (Alibaba), and even they are not that cheap. I do plan to ship a few things I am ordering to my gf in Poland, then get her to ship it here, overall that will be cheaper, but much longer. I've done a bit more research now, and I don't see any major safety issues with fabricating this. It's basically just a hand-held bunsen burner, not a welding torch, so there is no flashback arrestor required.

I don't have any intention of extracting cannabis oil, a normal joint is fine with me. And I have no need to make money doing illegal things, chartering worked fine for me until the tourists stopped coming here, but I still have an income from my freelance writing, so things could be worse. Though the pay from that is fuck all compared to chartering, but better than nothing.

The entire premise that such a device is unavailable in Cape Verde is ridiculous. Gas torches are ubiquitous. Available in hardware stores on islands both smaller and remote. In the distant provinces a vendor can order it from the capital city. The entire Amazon/shipping/customs hassle can be avoided.

Additionally, a torch is a much better long term solution, as butane here is $1.20/kg, and the refills in the Canaries for the portable bottles were $2 for 250ml. My main gas bottle is only 6kg, so not so large that I can't move it to where it is needed.

Anyway, if any of you do ever come here to Mindelo, here's a list of other basic items that are not available - 

2 part epoxy resin in quantities of less than 1 liter

2 part polyurethane paint, or any two part paint for that matter

small sizes if wood not available at hardware store - you have to go out of town to the big lumber yard, and it is expensive

blue painter's tape

normal grade sikaflex

The marina (a bunch a fcking twats) have a limited chandlery, but everything is 50%+ more than you might expect, 100%+ more if they have to order it in.

I guess they order their supplies from off island. There are only 5 hardware store here and I asked them all. All you are doing is highlighting your ignorance mate. I don't really appreciate being called a liar when I am giving useful information. Refill canisters are not available, so if they do use them then they use a big bottle. Also, copper plumbing pipe isn't available, they use pvc. Perhaps they use welding torches to repair fridges. Idk, but I am telling you the facts as they are.

Honestly, he sounds like a fine gentleman. Anyway, there is nothing more to be gained on this thread. I'm unsubbing. Feel free to troll on my future threads. Anyway, I have some kebab to remove in my EU4 game. Later :)

The entire premise that such a device is unavailable in Cape Verde is ridiculous. Gas torches are ubiquitous. Available in hardware stores on islands both smaller and remote. In the distant provinces a vendor can order it from the capital city. The entire Amazon/shipping/customs hassle can be avoided.

I would have thought so...

But if I'm reading this right the entire country imported $6,000 worth of welding equipment in 2018...which seems low for a country of half a million...that would put it a few spots ahead of Belize where I know you could rustle up a torch.

Of course you can find welding stuff especially out in the sticks where fixing things is more often done than in more populated areas. As I said, jaz is a troll.

OMG you are a piece of work.  You seriously are already blocking people after basically your first post???  Hopefully I am not the first.  Fuck off Newb, and show us your wife/GF tits....

I am w/ shag on this, already tried the fon, suyw/gft's but asshole is showing no fucking respect.  Let him blow his plugged up ass self up I say.

this is a shame, I really did think that for a moment there was a chance of a mate of this guy's holding his beer  whilst filming the incineration of whatever it was  that was meant to be fixed, oh well...

So, now that you fellas are done shitposting, sit yourself down and let me give you some realtalk. I'm not worried about offending those that don't deserve being offended, as it will quickly become clear whether what I am saying applies to you or not. 

I see you trying really hard to get a rise out of me, it must be tough on you that it doesn't work.  Pro-tip - liking eachother's shitposts doesn't make you look smart, all I see is a couple of losers jerking each other off. 

Anyway, what you are missing is that for you to be able to offend me I have to respect you and care about your opinions. Which clearly I do not. The reason for this is that it is painfully obvious, from your attitudes and statements, that you are armchair captains and daysailors with no real experience, hiding behind the anonymity that this site provides you. Us real sailors can spot each other, because we have tested ourselves against the ocean and not come up lacking - we have no need to be validated by strangers on the internet. Sure, we're all assholes too, but we have a grudging respect for each other through our shared experiences. 

This probably explains why you have been rubbed up the wrong way before by other steel boat captains - the majority of steel boats are cruising boats, and cruisers are immune to your trolling for the reasons I have stated - nothing annoys a troll more than someone that is immune to their trolling. 

Anyway, I doubt this will change anything, the only way that you will understand my points is to grow the balls you need to go out and become a real sailor yourself. This is not arrogance, it is the confidence that can only be earned by doing. If you can't do that, maybe you need a new hobby, or a penis enlargement, whatever suits you best, but you are impressing no one except other nobodies such as yourself - I realise that such people are in the majority, especially online, but if you actually go out into the world you will meet other people who's opinions actually count for something.

A real sailor would have found a torch among those islands. No problem. That's the way they roll. And what's wrong with jerking off? 

What's with the too numerous first person pronouns in your long missives? Work on your writing style or just post the requisite pics. You can get writing, sailing and torch building tips on YouTube. Why ask here?

Actually it isn't a bad idea.  I've seen plans but never followed through and built one.

As pointed out upthread, the venturi is the hard part.  The plans I've seen use a reducing T for threaded black iron pipe.  Some reducing Ts have a tapered pattern and that's what you want.  You want one like this:

Large -- T -- Small
.        |

.      Large

You adjust the sizes based on how much output you want the torch to have, and the details of the pipe sizes and corresponding orifice sizes that worked best were in the plans I once saw.

You then put one or more reducing bushings on the left to get it down to 1/4" pipe or 3/8" pipe.  Then you put an orifice inside the pipe, by drilling and tapping it and using a purchased or salvaged orifice, or by closing it off completely and drilling it precisely.  The other end of the pipe is your gas input, where you will want a valve and hose.  On the right side of the T you put a short piece of pipe, 6"-12" or so, that will be the burner nozzle.  The bottom is open and is the air inlet, and you can put a shutter over it if you want so you can adjust the mixture.

If you can't find a T with a tapered pattern you can still build it, but you might need to shape the inside of it with some clay or refractory cement to get the necessary tapered rather than stepped shape.  The exact geometry isn't critical.

Here is an orifice chart showing drill sizes:

Be careful, experiment outside away from anything that can burn and away from low areas where gas can accumulate, wear gloves and goggles, keep a fire extinguisher handy.

I'm told that it is possible to build these large enough that the infrared from the flame ball can be hazardous to vision, so keep your BTU input down to something reasonable (20,000) or take precautions.

Commercial torches use fireproof hoses, be cognizant of the obvious hazard if you don't.

There you go.  You can still post some nudes to the thread if you want, for karma, it's not too late.

Here's a design close to the one I described that uses a more readily available bell reducer instead of a tapered T.

In general, the metal casting and forging enthusiasts are the ones who know this stuff, so you can apply your google fu based on that.  They build them for high capacity but the concepts are the same and you can scale them down to the sizes typical of handheld torches.

Good luck, stay safe

can't you buy a new torch and gas bottle on the internet and have it delivered to wherever you are?

Apparently you haven't clued into the fact that the "reasonable engineering advice" being offered by the extremely experienced and knowledgeable people here amounts to "Don't do it - you'll probably hurt or kill yourself"

Meh, doesn't seem like it would be much of a loss for humanity.

Thought the troll was unsubscribing to his own thread but he can't help blowing his own torch as it were.  I appreciate the help and advice I have received here and have tried to give useful advice when I had something to contribute.  Hearing how well he respects the locals he must have to keep an eye on his back lest someone sneak up on him w/ a working torch and burn his ass.

, there's actually quite a lot of info online now that I looked properly

So you're saying you didn't bother to look before posting on here hoping to get some attaboys? Noice!

Honestly, I empathize with a lot of what you're saying about people's attitudes on forums in general, this one included. The vibe of 'you haven't EARNED THE RIGHT to hold a tiller" is obnoxious and also deeply, richly ironic coming from a group that also does threads a couple times a year wondering why young people aren't attracted to their sport/hobby/whatever the fuck boats are.

That said, the dynamic at work here is also one where your defensiveness is playing a big role. You didn't get the encouragement/ridiculously specific advice you were looking for ("any thermodynamic/gas flow-state engineers in the house? Can all the physicists who want to lend their PhD's to describing how I can do an arguably pointless and dangerous project please step forward?" WHAT! NO ONE? YOU HEATHENS!) so now you're insisting you actually never needed anyone's help, you found another solution, and fuck you guys anyway/you're the problem I'm going to get back to really (doing hobby)/bla bla bla. Cool.

A few years back I was in exactly your position on a climbing forum. Described a belay setup along with ridiculously specific questions. Instead of engaging the way I had hoped, I mostly got a lot of feedback that my overall system was poorly thought-out. I didn't want to hear that so a cycle began of me getting defensive/pusillanimous and them telling me in gradually more explicit terms to go fuck myself, idiot. 

Were there a bunch of pearl-clutching ninnies mixed into that group? Yeah! That belay system worked fine! Was the response -even from the non-ninnies - super inviting and friendly? No! Would it have all gone better if I just subtracted my defensiveness from the equation? Was my defensiveness the sole catalyst that turned the ninny-soup with chunks of 'yergunnadie!' into a solid block of shit? Definitely. 

So is yours.

(For the record, I'm pretty sure you'll be fine, and I would probably consider giving what you're describing a try if I were in a serious pinch, albeit wearing gloves and a face shield. My understanding is that broadly speaking the common flammable utility gasses will not burn without oxygen, and oxygen is inherently excluded from the system upstream of the regulator by virtue of the pressure of the gas. Which is what keeps propane from 'burning back up the tube' and 'exploding the tank like a grenade' in every cheap chineseum stove and torch on Amazon. At worst, I think you might get a shitty flame/flow and/or have a small explosion/rupture at/just upstream of your valve, followed by a small but poweful uncontrolled fire until you threw the fucking thing over the side. But none of that is particularly unrecoverable. Then again, I'm not an engineer, or any kind of expert at all. I also highly, highly doubt there are none available where you are. If there's indoor plumbing, there's little propane torches.)

Will somebody please just help this guy blow himself up?
