Thanks again for the compliment guys!
The elbow at the top is riveted and soldered. The column is attached to the pot with what's called a van stone flange. This joint can be disassembled. I seal this flange with rye flour dough. I went through 6 different types of gasket material before I took youralls advice and used rye flour dough. It seals beautifully. Thanks.
The seams in the pot are pittsburgh seams. The longitudinal seams are groove seams. These are all seams commonly used for ductwork and they are all soldered (except the van stone flange).
The different parts are made of varying thicknesses of copper from 1/16" on the bottom to 16 oz at the lyne arm.
It cost me a small fortune to build, but well worth it.
I did a lot of studying on this website as well as a couple books before attempting any of this. The time spent reading and learning was incredibly beneficial as most of the guys on here will tell you.
So far I have distilled some red wine for practice. It came out surprisingly good.
My first corn and barley was a little grainy tasting but the next time I slowed things down quite a bit on the spirit run and it improved significantly. I also made some apple jack, we pressed the apples ourselves (lot of work). I wasn't real crazy about it so I threw it back in the still with the feints and reran it, again at a slower pace. Now I have it setting on some oak and it is aging very nice.
My mashing and distilling skills are improving rapidly, thanks to you guys, this website and Smiley.
Cheers to all!
Here is a few close up photos. It's been used recently and I didn't have time to shine it up.
