Re: Tell us about your mistakes.

Guys...we need to get this clear. The SILVER solder is for all work EXCEPT the waterboxes. If you try to silver solder the waterboxes in place, you will melt the joins of the tube ends and endplates because thos joins are directly behind the waterbox joins. THAT WHY two (2) different temperature sol...

Just to be clear. When you say silver solder, do you mean brazing rods? ie high temp.

Soft solder melts around 200-220 C.
Hard silver brazes melt around 650-800 C.


Yup, correct.

Re: Tell us about your mistakes.

Your mistake was in silver soldering on the waterbox ends. The temp melted & breached the tube welds. In my original designs (see here) I told people to use SOFT solder on the waterboxes. Lower temp, therefore no breaches or problems. And soft solder only contacts water, so no issue with ethanol con...

Re: VM head Q

It seems like the alcohol would tend to "boil off" first. Alcohol will NEVER 'boil off first' . Ethanol (alcohol) is miscible (molecularly joined) in ALL PROPORTIONS with water. It takes considerable energy input to break that bond. Even then, ethanol and water will BOTH leave the boiler and go up ...

Sounds easy! Thanks Harry, I'll use the crimped system then.

Re: VM Project

The crimps in the vapour tube in the Liebig will work, but will also make it hard to clean out if you need to. IMHO, it is better of leaving it circular, and just put a thin strip of copper mesh loosely inside the length of the tube to get the turbulence inside it. Very easy to clean. Plug the end ...

instead of having a valve on the product tube, the valve has been put above the shotgun condenser. my theory is that when the valve is fully open the still will be at 100% reflux. when you start to close the valve, this will restrict the vapour flow to the reflux condenser and the vapour will have ...

I realize it is all soldered together but you want to make sure your coil is spiraling down hill the whole way.

Harry has nailed it about the vapour not rising up the product arm.

For two reasons: 1) The vapour collaps...
