This sound about right? It's running as i type. Gonna shut it down in about 15min and run the spirits. The water out of it smells and tastes like shower water, Is the best description i can think of.

Normally takes a bit more cleaning than soaking in heads to remove the oils. Not wanting to see you waste a run with contaminants suggest you read the posts on cleaning to get a better idea.
Degreaser, a rinse, a good boil in napisan and a clean water flush would be suggested as bare minimum.

Regarding cleaning the oil from the 100mm wide copper packing/mesh. I used a litre of very smell heads with a hi content of acetone to soak the rolls in for a minute. This cleaned most of the oil from the packing. Next to run the still with some more heads.

I removed 300 grams of SS pot scrubber packing from my 1.5m column.

For my 2" column I used 900mm of mesh per roll, which weighed 51 grams each.
I will put 750 g of copper into the 1.5 column.

Hari wrote:Hi Mac,
I am wondering whether my 2" column is packed too tight or too loose regarding my 51g and 900mm of length of each piece of copper mesh.
What was the length of your 91-95g please?
choppy wrote:How many pieces of mesh is too much/not enough.
I have the stock standard PD reflux still, the 2" packed section of this still is 350mm tall.
When I replaced the pot scrubbers with mesh, I filled the column completely with three and half pieces of rolled mesh.
After the first run I found the alcohol take off rate was painstakingly slow, I had the mesh too tightly wound.
I have since loosened the mesh to about 60gms per roll and used only three rolls.
The take off rate has improved marginally, but is still very slow.
I know slow is good, but this still seems too slow.
With the pot scrubbers in place the take off speed was at that point where the drip tries to become a needle like stream.
With the mesh in place it drips slowly like a leaky tap.
Do i have too much mesh in place?
