Amazing! You have completed a torch from my poorly drawn diagram. The original torch cannot be disassembled, so I drew it from my imagination. You have completed it and it works perfectly. You have proved my imagination right. You are a perfect engineer.
Thank you. Your simple sketch was a logical deducement. It made sense. I have years experience in fabricating small parts and it was a pure joy in cobbling this torch. I am going to make a second one and record the process for a video this summer.
Thanks. In its simplest form, it is a whistling tea kettle. Instead of water, denatured alcohol is boiled and its flammable steam is allowed to escape through a tiny aperture at the bottom of the “kettle”, passing over the alcohol burner, which ignites the pressurized vapor.
@@JohnSmith-il4wi i trimmed the pipette so that it was centered above the wick to maximize the venturi effect, and the other end in the middle of the “bump” at the top of the tank. I am making more tanks with different apertures in the pipettes.
@@beshkodiak Fantastic. My take on this design was getting quite frustrating, mostly because I only have soft solder and no high heat brazing equipment. My joints were falling apart from the intense heat. Now I am using clamps and it works very well. Not being able to easily fill the top reservoir was the main reason I went with my own design. My top chamber has a brass t fitting and a screw on/off cap. Other than that it functions the same
I saw this torch the other week and have been designing a couple different torches, just tinkering and learning. And you went and made the coolest one of the lot!!!
Very cool! I've been surprised to learn recently that a "blow lamp" can be made even more simply than this. Surprised again now with this self-powering design without too much more complexity. I wonder whether this could burn oil, which has a higher boiling point, and whether the flame could be improved with a venturi pulling air in with the vaporized fuel, and the fuel/air mixture maybe modulated with a simple throttle valve on mouth of that venturi.
@@bumpty9830 certainly room for experimentation. Remembering this is 19th century Japanese technology, there may have been stand-by tanks that would be switched out to maximize productivity, along with other tanks with different venturi ratios and other orifice sizes. I have never actually seen one of these torches, just some images on youtube, but with 60 years in metalcrafts i was able to intuit a workable model.
That occurred to me, too, @@beshkodiak, that units with a variety of orifice sizes would probably be available the same way you have different drill bit sizes in a metal shop. Nice work! It certainly does the job.
@@brianhasko9240 Brian, the main lamp heats up the 2nd stage, which is a saddle tank of fuel. Out the bottom of the tank is a copper tube with a 90 degree bend. The fuel boils and ejects vaporized alcohol like a tea kettle. There’s a venturi effect and bam! A flame jet. See my 3 part video on making one.
You are right. This video captured the trial to see if the device would actually function. My next video will explain how it works and then actually heating/burning something.
I reckon you have loads to offer, carry on posting, your channel is actually interesting
Just posted chapter one of the construction of this blowtorch

See my new video on how to build this!
would love some video commentary on how it works

Fantastic! Im building one now with copper pipe and brass fittings. Dis you have trouble finding the perfect nozzle height and position in the flame?

Wow excellent! Greetings from Costa Rica!

Wonderfully done
New video of building this blowtorch
Very cool!
Awesome
@@mohammedimran3670 fun to make too! Check my videos on building one
Wat, how is it blowing without air, is it pressurized fuel

@@beshkodiak Wow I would have never thought of that. Very nice. I’ll be sure to check out those videos
If I could give one critique: You can't post a video like this and not put the flame up against a piece of metal or at least burning a piece of paper.
You are right. This video captured the trial to see if the device would actually function. My next video will explain how it works and then actually heating/burning something.
New video on its fabrication
Keşke aynısını yaparak video ya alirsaniz sevinirim
I have made a 3 part video on how i make one. Please watch.
