home still: dephlegmator update

Here is an update on some work I have been doing for the still. I have mainly been working on the dephelgmator section.

Internal shell parts.

The plates were all waterjet-cut with the holes slightly smaller and finished with a uni-bit drill. The diverter plates are the semi-circular plates in the picture.

Dry fitted together.

I dry fitted them first to figure out the best way to braze them together. I decided it was best to braze the center tube to the diverter plates first.

Center tube brazed to the internal diverter plates.

I used two other tubes to help align the plates. I like the colors that came out when the copper was heated. It's too bad they will be hidden.

Completed internals.

Some of the plates weren't perfectly aligned and some of the plates bent when inserting the outer tubes. I was able to make it work, but it was not visually appealing.

Major components of the dephlegmator.

I decided to bead blast the interior to remove the oxidation from the inside.

Next will be the final assembly.
