Winding a double helix copper condenser coil from 6mm copper tube for use in a 50mm reflux column. Made the winder from an old boat trailer winch, 16mm stainless tube, scrap iron and a cambelt bearing from a Mazda Demio. It is easy to wind the outer coil by hand but the inner coil is a bastard to do by hand. Wasted metres and metres of copper tube trying! It takes only a few minutes to wind the coil and filling the copper tube with salt is the most time consuming. It is certainly not the most beautiful coil I have ever seen, but it works like magic. The coil is part of a still project we are working on and I will make a video of the finished project once we are done with it ...... eventually!!

not very pretty he says. I love ya modesty almost as much as this coil technique. Its brilliant. Just shows that no matter what problems that need an engineered solution, theres always a brilliant mind that thinks outside the box and finds one. Brilliant.
Thank you VERY MUCH for your kind comment. I really appreciate that. I Think part of thinking outside the box is not having money to have things made and just having to make it yourself. :) :) Keep safe. Cheers.
Godamn man, you are a genius. I remember coiling 1/4" copper tubing -- or trying to -- to make wort chillers, maybe 20 years ago. I probably wasted $300 worth of collapsed tubing before I realized the tube had to be FILLED with water or sand while I was bending it. d'oh
Didn't have a neat little jig like you put together, though.
Nice design,;seems to work like a charm.
Thank you very much. Took quite a few attempts to get it right and wasted about a coil (15m) of 1/4" tube before I got the first working coil! :)
@@LouwrensvanderMerwe I remember years ago riding a merry go round at the country fair when I got the idea of filling copper tubing with sand salt or water even freezing the water for ultra tight bends. Great minds must think alike even if they are on the other side of the world. Peace and good luck. VF
Brilliant! Such a simple device to make i love it thanks
Thanks. Really appreciate your kind comment.
Thanks for your comment. I like people with a sense of humor that can take things with a pinch of salt. Life is far to serious! The copper tube I used was refrigeration tubing and it was really soft and very easy to use. During the winding it "work-hardened" of course, but it did not matter as it was not going to be worked again. Since winding the coil in the video I have made 6 more and they look really nice.
where is Pt 2 At ! Im in supence ..
@@LUCKYB. Sorry, very stupid of me not putting up a link. Part 2 is here: bit.ly/2Tp9gR8 . Thanks.
Nice job, lubing that shaft!!!!
very nice ! perfect
I am not sure I would use one so small. that is just too small of a dia tube. but damn, you get an A+ plus extra credit for the idea and creativity. super great idea. now for you to scale it up to 1/2 id tube.
*BOWS* excellent Sir!
Much appreciated! Please watch Part 2 - winding the outer coil on the same winder. Cheers.
Great use of the winch! I think you inspired a whole bunch of viewers.
Was that done with annealed utility grade coiled copper or refrigeration grade copper?
I thought "lubing the copper?" (or shaft as spdjnky42 says) then it all made perfect sense as the show realy got started. The whole operation looks like it takes a fraction of the time it would take without the winch and the lube. And I do say that last part carefully and not out loud.
Love your music, let thing of grandfather...
Thanks Steve. Got the music from Bill Beets, a dear Dutch friend of mine.
Louwrens,sorry about the Boks,perhaps next time.I purchased a Still Spirits 25 litre Super Reflux still some time ago,Trade-Me from deceased estate.Used the still 2day and at first my spirits were clear,yet after +/- 500ml it became cloudy.Any reason why. Dankie Johann
Very nice! Your tools and technique could be used for coiling many different types of wire and tubing.
Yep, lots of experience! Thanks for watching.
Hi there Louwrens thanks for answering my questions. I never thought that the acidity would make a difference. I recently tried to make a wash of 35lt of lemon mampoer. My first mistake was to use turbo yeast. I had a stalled fermentation, I tried adding more yeast then yeast nutrient then oxygen. Nothing worked. Have you any suggestions? I do not want to throw it away (between my wife and I we squeezed 8.5lt of lemon juice)
Hi Ian, to be honest with you I had two tries at fermenting lemons and could never do it successfully. Always ended up with a stuck fermentation like you. Lemons have very little fermentable sugar and is very acidic.
I had more success with alcohol macerated lemon peel which I have distilled in my Pot still. Remove the peel before distillation!! There will also be some lemon oil in the distillate which can make your alcohol cloudy, but adds to the taste. Add sugar and you've got something close to Limoncello.
The only suggestion that I have is maybe you can add sugar (6kg) , a handful (or two or three!) of Oyster Shell Grit, about 50g of DAP (Di-ammonium phosphate), some Vegemite or Tomato paste and bring the volume up to 25lit with water & add 20g of fresh wine yeast (rehydrate it first before adding to the mash). This is totally a shot in the dark and I may be far off. I wish I could give you better advice, but try it. Good luck my friend!! Cheers Louwrens.
@@LouwrensvanderMerwe Thanks Louwrens I will make wine out of it
I wound a beautiful coil.(1/4") Filled it with fine sugar. Now trying to blow the sugar out. I've just been running water in it then blowing. It's not kinked but cleaning real slow. What kind of a pump do you have? Any suggestions?
I usually connect the coil to the garden tap, open it up full blast and wait. It does take a while (sometimes 15-20 minutes) for the water to come through. At first you will only see a few drops coming through and then more and more as the sugar gets dissolved until it turns into a stream. Just be patient it will get through. Connect to the municipal water supply, turn open and walk away! Good luck. I know the anxiety this cause!
Thank you for the info. My problem was patience. I will try this. How do you get the garden tap reduced down to the 1/4"?
juliaetta I took a regular Gardena hose connector and pushed a heated piece of 8mm copper tube through it. The copper tube melts through the inside and creates a watertight seal at the same time. I then just connects the plastic on the copper tube. You can see a picture of it here: mampoer.co.nz/tn_Hose%20connector.jpg
Thanks a bunch for the information.
Will this machine work on a 3/8" tube?
This specific machine won't work with 3/8" tube, but this type of machine will if you change the shaft tubes (which you use to wound the copper tube around) to suit the diameter of the tube you want to coil. This setup with the boat winch as the "gearbox" is very powerful and will easily coil 3/8" tube. You do not have to use an electric motor and pulleys like I have, if you use a boat winch with a ratio of 5:1 or higher you can just connect a strong industrial drill to the handle shaft and use that as your power source (The drill will need to have a chuck that can take 19mm drill bits). Cheers.
May I ask what the diameter of the mandrel is? I'm building a Boka now.
For the small inner coil it is 16 mm and for the bigger outer coil it is 32 mm. Cheers.
Hi Louwrence had you check my new reflux condenser design I built
Wow! I can see A LOT of work has gone into building that and it looks amazing. Hope it will give you many happy hours of distilling and a very pure product! Well done. Louwrens.
Good engineering but terrible music.
Thanks. Take a look at Part 2 - NO music!!
