54mm Brass Column Boss
I have managed to locate some items and adapt them to make it easier to attach and remove the main column of the still. This is for cleaning and storing. All you have to do is solder it into place. It’s then just a matter of screw it on and unscrew it when finished. You must use lead free solder for all soldering activities for the Still, or of course Silver solder is a better option but much more expensive.
I use the lead free plumbers solder. If it’s good enough for us to use in our drinking water then it’s good enough to use for distilling.
Picture five shows the inside of the fixture with the tube inserted and all that is required is for it to have some flux applied, heated with the blowtorch and the solder run in. Both pieces of the boss are brass so they can welded if you are proficient with that implement or brazed, again not easy or the easy option, solder. The piece that attaches to the body of the still needs a 68mm or 2.7inch or 2&23∕32inch hole in the top of the still where the column will be fitted. The female part of the boss will need to be fixed into this hole by your preferred method ready to accept the column.
These bosses can also be made to take columns between 54mm and 28mm pipe size.
