To Sam-
1 - I am sorry to have broken the rules of over 100ltr. It is a hobby mate, I will never and have never done anything other than use product for personal. If cutting 1 tank down to 100ltr is easier to run or has any advantages I will do it. It will just make me cry haha.

I have not watched any vids, just trying to read and understand. Anyone can buy a still and run it too the manufacturers instructions. Sorry if you feel the need to bag me out for having a go.

Unique to the VM setup, the take off point diameter interacts with the column diameter, creating an automatic reflux ratio. You have a 98 to 13? size difference, a bit under 8:1, that means that 8 parts of the vapor will be returned to the column as reflux for each one part that makes it to the pc to be condensed, no matter how far you open the valve
Currently the unit will run faster in LM mode
Without changing the head type completely, the obvious solution is to put a multi tube shotgun condenser (or another coil condenser similar to the one in the head) there instead. The current valve will still give you at best a 2:1 ratio

At the end of the concentric cone (100 to 50mm reducer) I have made a washer on the lathe which has a 33mm hole. I was aiming at 1/3 diameter difference only because of plans I looked at. The valve is 50mm but as explained just before the thread inlet I put the 33mm diameter washer. I don't know if that's a good or bad thing.
RC Al wrote:The washer is of no consequence with the liebig diameter being smaller
It will be a issue if you change the condenser
RC Al wrote:A ccvm would mitigate the need for an bigger valve, but you will still have the ratio issue. Putting a condenser below the take off point will change it to a CM and the sizing ratio issue will go away (the top of the column will need to be sealed for that to work) used with a CM your liebig most likely will be fine, my 3/4 over 1/2 at 170cm (copper though) is knocking down 12l/h on strips at the moment and still has more to give when i can work out how to get better efficiency out of my burner/shroud
A 33mm or bigger bore liebig could be made to work, but would need turbulence inducers to ensure contact with the walls to condense, whatever you use to do that will also influence the ratio - the vapour dosen't see size, it feels resistance
RC Al wrote:That will depend on how much heat you throw at it, if you used all the elements (12kw) it might hit as high as 4.5l/h (based off an old calc), but your packing may not allow you to use that much heat (flooding) and I cant comment on how much smearing would happen, The extra column height helps with that
I am keen for you to run it as sits if you are :)
Dose that inkbird controller let you set watts and not a temp?
