RE: [new_distillers] Still modifications
- I had a similar problem and I removed the lower tube by drilling it out with
a 1/2" drill and using a broom handle knocked out what was left of the
centre pipe. I then silver soldered two small patches of copper sheet over
the holes. This has been very effective and with a bit of sanding and
polishing you can hardly notice the modification. Another thought that I
had early on was to sleeve the lower pipe with 7/16" plastic tubing and keep
using it as I had a still maker design and this was part of my water path.
My thoughts were that the plastic tubing would insulate the water from the
copper and help stabilise the column. My reason for not testing this was
that I was concerned that I could not remove the pot scrubbers from the
column and I doubted that I could effective clean the column without
removing the scrubbers. What I can tell you is that when I removed the
scrubbers I did find a small amount of oxidisation of the copper. This had
probably occurred when I had not dried the column properly after cleaning.
I have also remove the top pipe and installed to 1/2" pipes through the top
of the column.. These cooling pipes are not connected to the condenser as I
have had problems in the past with stability due to positive feed back loops
and wanted to avoid them.
