- I started this project 4 years ago with this video:
www.youtube.co...
and I have now, at last, managed to finish the project by motorising the coiling machine. www.distiller.co.nz
Double helix condenser coil is the general term used for these coils, BUT it is actually single-path, double concentric counter-wind coils! :)
With music like that, any kind of work is pleasurable and helps time go by fast!
Thank you very much! Appreciate that. Cheers.
Man, if you are building a still you should watch all this guy's videos. Top notch.
Thank you for your kind comment, much appreciated. I like what you're doing on your channel, keep up the good work. Nice moustache!! :)
Sealed of water then freeze . They freeze instruments to bend them. Quality work sir.
Thanks for your comment. At the moment the salt works for me, but water will be easier to work with and faster. Unfortunately I do not have the facilities to freeze long pieces of tube at the moment. Cheers. Louwrens
Nice!
Looks a whole lot easier than how I did mine! haha
Thanks.
how did you do yours
Yes, unfortunately, I still use salt to fill the tubes with. I am somewhat between a rock and a hard place now that I started selling the Boka stills & heads and I just have to fabricate perfect coils and can only do it with salt (for now). However, I discovered that I only have to fill the first 1.2 meters of the 3 metre tube with salt to prevent the small coil from collapsing and that amount of salt flushes out within 5 minutes. Because the larger outer coil is more than 6 times the diameter of the tube it doesn't need salt and won't collapse when coiled.
what about sand, have you tried it instead of salt?
Sand is very difficult to flush out of the coil since it doesn't dissolve
MAGIC, Pure magic. Great vid.
Thank you for your kind comment. It is much appreciated. Cheers.
You are a Master Louwrens. Well done!
Many thanks! You are very kind. Cheers
enjoy you're movies :) borrowed your design and made my own Boka still her in Norway with great result :)
Cool! Post a video some time. Enjoy your still.
I would be interested in purchasing one of the 1/4" coils if you're in the USA. These would be great for "Prepper" types with rocket stoves. It's a great setup for heating water through the rocket stove vent.
Unfortunately I am in New Zealand, but you have an excellent idea.
Just Brilliant, do you pinch the ends of the pipes off after filling with salt , compressed air helps fill the tubes up with a funnel and air gun... Love the double coils though.......
Only half of the tube is filled with salt and only the end on the side that is filled with salt is pinched closed and folded over for about 1cm. The other end is open. Only the length of the tube that will form the small inner coil needs salt to support it from collapsing. The bigger outer coil is more than 6 times the diameter of the tube and will not collapse. This is how I fill the tube with salt: th-cam.com/video/f7wbEspYdHM/w-d-xo.html , but nowadays I only fill half of it. Cheers.
@@LouwrensvanderMerwe thank you very muc for the information. great.
Thks & interesting, I like how you put a sleeve-pipe over/around the 1st coil to make another coil around the 1st.
You-know if you put an extension handle on that sleeve-pipe, I might be able to wrap the 2nd coil by-hand (whether using the an electric motor).
Of course I would freeze soapy water in the tubing & seal both ends first.
Let me know what you think.
Thanks for your comment. In this video of mine you can see how I (at 3:45) turn the outer coil by hand - th-cam.com/video/cztNIWe0ipg/w-d-xo.html . Cheers.
@@LouwrensvanderMerwe Thks, you have a PhD in condenser coil bending.
Oh, this fellow is pretty good too. Before the bending, he fills the tubing with soapy-water & freezes it:

I’m impressed
Thank you very much. Cheers.
Amazing machine
Thank you very much!
great work!
Many thanks.
Outstanding...🙏
Thanks a lot 😊
Hi man fan of your work. Do you still put salt or water inside the tube?? And did you made that machine to roll the coils or bought it?
I still put salt inside the tube, BUT only in the FIRST HALF of the tube which I coil the small inner coil from. The outer coil doesn't need any support. I have built the machine myself from an old boat winch. You do not have to use a motor you can crank it by hand like in this video - th-cam.com/video/t5WfPeLX1V0/w-d-xo.html . Cheers.
Holy crap! or as they say in the old cuntry "fok my" . This is genius! Thanks for the informative channel! :D
Thank you very much! 'n Boer maak 'n plan! :)
Great video! I see you have gone back to filling the tubes with salt? In a previous video you suggested using water was a better way.
Yes, unfortunately, I still use salt to fill the tubes with. I am somewhat between a rock and a hard place now that I started selling the Boka stills & heads and I just have to fabricate perfect coils and can only do it with salt (for now). However, I discovered that I only have to fill the first 1.2 meters of the 3 metre tube with salt to prevent the small coil from collapsing and that amount of salt flushes out within 5 minutes. Because the larger outer coil is more than 6 times the diameter of the tube it doesn't need salt and won't collapse when coiled.
@@LouwrensvanderMerwe how to remove/flush the salt? I tried but cant flush it by water
@@sushmitacajes5189 I made a 3/8 , filled with salt and couldn't get the salt out either. I left it sit in hot water for an hour and tried to flush it with tap water- no luck. Too bad beach are it rolled nice with the salt and looked great, but I kinked it trying to bring the tail around and loop the top. I found the copper very soft. I ended up not using it and am about to make a 1/4inch one now - just refreshing my memory with this video.....cheers
Fantastic
Thank you very much. Cheers.
nice!
Thank you! Cheers!
Good job with Soft copper what happens with hard copper
Hi Bill. I don't know how coiling hard copper will work as I've never tried it. Would be interesting to know. Maybe you won't need to fill the tube with salt to prevent it from collapsing, but it might also crack. Really don't know. Cheers. Louwrens
good
Thank you.
would there be any difference, if you were to wind the second Layer Anticlockwise?
No, it will work just as well. The orientation of the coils is of no concern. Just make sure you do not flatten or pinch the coil when you reverse direction. Cheers.
OK Thanx :)
Awsome
Thank you sir. Much appreciated. Cheers.
Why salt, not for example... sugar ?
I asked around and some people many times more intelligent than me explained to me that it has all to do with the Crystalline Structure of the two (salt & sugar). They say due to it's Crystalline Structure Salt has a much higher compression strength than sugar and salt will stay stable under compression while sugar will collapse much easier. I hope they are right! :)
That makes sens.
What about sand?
Sand will not dissolve in water and once you have compressed the sand in the tube you will never get it out.
Post where someone can purchase these coils.
I don't sell the coils anymore. Can't make them fast enough for my own use. www.distiller.co.nz
could you tell me what the outside dia. is of this coil,
Sorry for the late reply. The OD is about 44mm. Cheers
Thanks GREAT job and Video
Sir what is the length of the condenser coil?
and what is the outer diameter of the stainless steel pipe used for coiling?
And what is the height between condenser coil and the head cover?
And what is the wall thickness and outer diameter of the sleeve pipe?

@@LouwrensvanderMerwe sir do you think using charcoal stove with fan is dangerous to produce 95%
@@metalhead7752 No, I don't think it is dangerous as long as you keep the ethanol well away from your heat source/open flames. It is no more dangerous than the guys that use gas, wood, coal or peat. I must stress though - KEEP A FIRE EXTINGUISHER AT HAND AT ALL TIMES DURING YOUR STILL RUN! Even if you use an electric boiler. Cheers.
How do you keep the copper tube from crushing?
I fill the tube with course table salt (Kosher salt I think they call it in the US) and use a mouse sander to vibrate the tube to pack it in. Usually you just have to fill the length of tube that will make the small inner coil and you do not have to fill the tube that makes the outer coil. With the 1/4 inch tube I use 50 grams of salt and that will fill about a 120cm length. Cheers.
Gostei muito da musica.
Muito obrigado! (Hope I got it right?). Very kind of you. Cheers.
what is that amazing music !?
T. ALBINONI: Concerto for 2 Oboes in F major Op. 9/3, La Serenissima - Cheers.
God bless You maaan !
tkyou
Thank you for watching. Hope it helps. Cheers.
@@LouwrensvanderMerwe ohhh boy it helps a lot dude... cheers!!!
Would have been better narrated without the annoying music
I am yet to find a soundtrack that pleases everybody. My latest videos are all "silent movies"! :) Just mute the music and watch the video. Cheers.
@@LouwrensvanderMerwe Good answer !!
@@paulipoika :):) Thanks. Cheers.
