This easy to make flux is very cheap.
It is simply a mixture of the resin flux Kalifonia and isopropanol or denatured alcohol. It is extremely effective and does not give off an acrid smell.
Get Kalifonia on eBay - Cheap.
To make it, I add some Kalifonia chips to an empty pill bottle and then fill the bottle about ¾ full of alcohol. The flux will immediately start to dissolve. You may have to let it sit overnight to completely dissolved.
Once my initial add of Kalifonia has dissolved, I add more until finally it does no longer dissolves. At that point I have a saturated solution. And a flux at maximum strength.
At max strength it develops a beautiful amber color.
Let me show you how good this flux is. Here are two dirty pieces of scrap brass. Now I would never try soldering anything like this if I was serious. I do this just to show you how good this flux is and how it will overcome any spots on work that really weren't cleaned that well.
I just apply some liquid flux to the brass sheet and then apply solder. This brass sheet is a large heat sink. I have a small tip on the soldering iron so it takes a little bit of time to get the parts to temperature. Actually, when I have a large heat sink like this, I will often assist the soldering iron by using some hot air. I show you how to do that in another video.
Look how this joint is made. You can’t find a better flux.
This video has very much earned my subscription and like. Here's to many more.
If you solder a bit take a look at this playlist.th-cam.com/play/PLLYkOTQM-OSVE8HXrWvwaOvOsy0-Hu4u3.html
Unlike most DIY flux recipes, this one should work marvelously, since the Kalafonia flux is actually an activated flux (MSDS says
I love it. And it is a great insulator. When I solder LEDs to magnet wire, I lay the joint on solid kalifonia and touch it quickly with the iron to melt resin over the joints. I hope you subscribe.
TheWorldOfRail If you like using solid flux that way, you may wanna consider making yourself a gel flux, too: just take the solid flux, crush it into small granules (but not powder, which will reclump) and dissolve it into a much, much smaller amount of alcohol. Think 80% solids instead of the 5-30% in a liquid flux. It will take days, if not weeks, to fully dissolve. But you’ll end up with a thick syrup, like honey*, that can be applied beautifully with a tiny squeeze bottle. (An old eye drop bottle would probably work well.) Viscous flux like that is great for heavily tarnished workpieces, or where tackiness is helpful to keep things from flying off, like with surface mount components.
*In fact there exists a German brand of flux whose brand name literally means “soldering honey”.
Good advice. Will do it this afternoon.
TheWorldOfRail Lemme know how it turns out for you! :)
It is great. It is almost like a glue. Will make a video on making and using it. Thanks again.
A less saturated mix works well on things that require deep wetting such as stranded copper wire. I can confirm that it works good on not shiny stranded wire with not shiny recycled solder. Actually it works better than some "SMD" low cost or wholesale soldering fluxes I got from ebay, as that stuff is very weak at cleaning. I used the same brand of colophony as shown in the video, whose can says "activated", as pointed out by Antonio Tejada.
Thanks for the info.
Good stuff, great for my electronics soldering!
It sure is!
Thanks for the video. I'm planning to try to make some.
Have fun!
Very informative. Thanks.
Glad it was helpful!
Great info thank you!
I use it all the time.
Thanks SO much :)
Sure enough. Please be so kind as to like and share the video. It really helps us.
Thanks my man
Happy to help
Thank-you
Glad to have helped
Can this be used for water pipes?
probably. i use it on small copper pieces so I would expect it works on larger pieces.
Hi Sir I tried making this kind of liquid Flux with pin rosin and IPA however after resting for 24,48 hrs, my flux failed i mean , the rosin got rock solid form deposited under the alcohol in the bottom. I used 1 parts of rosin 2 parts of ipa . what must be gone wrong please guide
I really don't know. I have never experienced this. Did all the liquid go solid? If so, add more. That is just a guess. Maybe someone else in this section can help.
@@ModelSceneryTutorials no as I said my rosin didn't get dissolved and formed as solid at bottom of bottle as residue and IPA is separated floating above.
And believe me I tried thrice and failed all the times.
@@ModelSceneryTutorials one more thing I tried 1part rosin 2 parts IPA...is this correct composition?
I use maybe a half teaspoon on top of resin to make a paste. For a liquid up to 20 to 1. If it is too thin, I add a few more chips of resin. Try changing the resin.
Solid flux is terrible to work with. Thanks for the tip.
You bet

How to make flux. Okay, so the first ingredient is flux. ;)
OF course. The video is about making LIQUID flux out of solid flux.
