How to Make a DIY 900°С Mini Alcohol Burner




Introduction: How to Make a DIY 900°С Mini Alcohol Burner


Step 1: To Do a DIY 900°С Mini Alcohol Burner You Need!!!

In today’s video I am going to share an interesting idea about how to make a DIY 900°С mini alcohol burner at home!

Step 2: to Make a DIY Mini, Easy to Make and Almost Safe Yet Powerful Burner Is Not Difficult.

A DIY mini alcohol burner made at home suits perfectly for for baking wood, ( giving it flawless texture before varnishing it), and for soldering and desoldering of radio parts or wires.

Step 3: Mini Alcohol Burner Perfectly Performs Its Functions and at the Same Time It’s Very Economical.

Adding a compressed-air bottle or modernising the burner makes no sense. The burner is a small and compact item.

Step 4: It Does Its Job Quickly As May Have Noticed, That Is the Beauty of It.

I`ll keep my fingers crossed for you! Go, invent guys!)

    i'd be worried about the flame being sucked back into the bottle when the pression is realeased.

    isnt it a real issue ?

    Hi Jef.. Good thinking. Have a look 2~3 messages above.. Might be a solution.. ?? M.

    I think your intro says it all....."Almost safe". There is no such thing as, ALMOST SAFE !. Fire and PLASTIC containers do NOT mix, under any circumstance.

    The issue of blowback is a real concern, and your responce of, "you should be fine" is right up there with "almost safe".

    And if you sayyyyy, DROP IT ? It is NOT a tight seal container. Or if something hot even touches it ? A little common sense goes a long way. So does, "almost safe", all the way to the hospital !

    What about inserting a tiny "flash back arrestor " in the air tube... It could be done by maybe pushing some fine steel wool in the inner end of the fine air tube.. Can't think of any problem using pure alcohol... But steel wool might rust if methylated spirit (the purple stuff) is used... Because of the water content in the meths.. Maybe use very fine grade stainless steel wool ??

    For about 15 years of my life, I repaired at least 100 large modem or computer boards to component level every day of the week and always used a 800 degree tip on my solder iron. I was replacing 8 pin to 100 pin LSI The idea was to get in and out fast so the heat had no time to spread into sensitive components. It worked very well as I'm sure this will. As far as it getting to 900 degrees, I used to use alcohol burners while in grade school to melt glass. It will be hot enough. As far as the alcohol harming electrical components, I usually used alcohol to clean the boards and components after I made a repair so you could hardly tell a repair had been made to the board. If not alcohol, then acetone or liquid freon although the freon is much harder to get these days and acetone is just nasty. I like this thing but I'm not so sure it wouldn't blow up if you sucked too much flame and oxygen back into your bottle. Flame alone would probably not explode in the bottle without some kind of oxygen in there. This is really a good soldering tool if it is safe but I can't speak for it's safety record. Thanks for the idea. Hope nobody gets hurt...

    On top of the fact it could melt or explode the alcohol could do nasty things to the plastic and electrical components can be damaged at temperatures of 400 degrees so I doubt 900 is going to leave them in a fit state to use IF it reaches 900 degrees, which I highly doubt.Also that sort of amount of alcohol could blow you're hand off!

    It can indeed reach 900 degrees... Tested it... But I partly agree with you because I had to make adjustments... and yes, modernize it as the instructable told us not to...

    Where do i get the tube?

    On top of safety concerns I do not recommend to use electronic components that have been desoldered at such high temperature.

    Electronic component have to be used within the specification limits, the temperature reached during soldering and desoldering operations are in the datasheet. My suggestion is never exceed 240/250dC.

    Tin melt at ~220dC, there is no real need to go over such temperature.

    Sorry to say, but I've seen a bottle like this exploding while there was less than half alchol inside. You can immagine the scary. A friend was very lucky to have not reporter any burn on his skin.

    maybe i should be fine, but not being fine would end up in half a bottle of alcool exploding in my hand, so, would you elaborate a bit on why you think that should not happen ?

    also, from the video, i'm not sure if the small tube is supposed to plunge into the liquid alcool (thus projecting a tiny stream of liquid) or not (thus projecting alcool charged air, which would be more likely to be sucked back into the botle, imo)

    The small tube doesn't go into the alcohol. The air in the bottle is going to be more or less pure alcohol. I think that the blow-back problem is probably pretty unlikely for that reason - there's not enough oxygen in the bottle to ignite, and as you release the pressure, the tube is long enough that the flame will go out anyway. Just guessing, but I'd be pretty comfortable with using it.

    you can buy these at most jewellery supply stores for under $5. just saying.

    I think you might be on the wrong site.

    You save me in my car!

    Great idea Roman ... I use a heat gun from Harbor Freight to remove items from old boards but it has a big heat area if you know what I mean. This is more on the "spot heat" side and is MUCH better. Thanks!

    Hmm interesting project.

    You should add step by step instructions for those who can't watch the video, or might want to print out the instructions. As it stands now, there is no way anyone would know how to complete this project if they can't watch the video.

    Good stuff roman. The shoelace should be cotton and the bottle filled only half. Be careful cause alcohol and plastic is a flame waiting to go wrong. Less so if the bottle was glass, but you can't squeeze it :)
