![]() Apply flux to both of these areas, then, drop the round bottom into the boiler, making sure it fits snugly, sitting on top of the tabs. Use a wire brush or sandpaper to rough up the outer half an inch of the circular bottom, as well as the top of the tabs (if you haven’t already done so). Once the boiler is round, you’re ready to install the boiler bottom, which is simply a circular piece of sheet copper that is small enough to fit into the boiler, but big enough to fit snugly. Once the boiler seam and rivet penetrations have been soldered, use your hands to round out the boiler, making it as perfectly round as you can. Excessive heating will cause soot to form on the copper, preventing solder from sticking. Also, apply heat sparingly and remove the torch from the copper as soon as the solder starts to melt. In other words, if you have an adjustable torch, dial the heat back to medium low. When soldering, always follow this rule: slow and low. After the flux has been applied, use a standard propane plumbing torch and seal the entire seam of the boiler, as well as the rivet penetrations, using standard lead free plumbing solder. You’ll round the boiler after soldering, which we’ll describe next.īefore soldering the boiler seam, apply water soluble flux to the joint. This is normal and actually makes solder easier to apply because gaps in the lap will be smaller. Once rivets have been installed, the boiler likely won’t be perfectly round. Follow the same process for the remaining rivets. Hit the rivet until it expands just enough to hold the boiler lap together. Place them into the rivet holes (they should fit snugly) and position a hard object under the rivet (anvil, hammer, etc.). Clawhammer kits include the rivets and the boiler comes with pre-drilled rivet holes. Brake rivets work great for this and can be picked up at most fastener stores. If you’re supplying your own still parts, you’ll need to acquire some solid copper rivets. If you’re fabricating your own parts out of raw copper, drill rivet holes through both pieces of the lap using a standard cordless drill. This will make it easier to fill the seam with solder later. Once the boiler has been rolled into a cylinder, use sandpaper or a wire brush to rough up the areas where the copper will overlap and then secure the lap with locking pliers. Once the tabs have been cut and bent, roll the sheet into a cylinder by bending the copper so that the short ends of the rectangle overlap one another. The tabs form a ledge for the boiler bottom. Then, bend the tabs toward the main section of the boiler at a right angle to the main section of the boiler, using a pair of pliers. Use a wire brush or sandpaper to rough up one side of the tabs. If you’re fabricating your own parts, use tin snips to cut small “triangles” into one of the long edges of the copper. Clawhammer Supply kits are pre-cut and the boiler already includes tabs. The boiler is a rectangular piece of copper with “tabs” cut into one of the long ends. Wear the safety glasses the entire time you’re working, make sure to wear the gloves when handling material or using the torch, and wear the mask when soldering. A vice would be handy but is not necessary. You’ll need a few basic tools and materials in order to build a copper still: hammer, plumbing torch, pliers, small clamps, sandpaper, lead free solder, water soluble flux, work gloves, safety glasses, and a VOC mask. This design allows for greater efficiency and versatility than a dedicated pot or column still. The design described in this article is referred to as “hybrid column still.” It’s a basic pot still that also includes a column, which may be filled with packing material to induce natural reflux. This significantly reduces the time and cost associated with R&D of new potential products. However, our stills can be used as small scale pilot systems to run scaled down versions of recipes intended for larger equipment. Licensed commercial distillers probably wouldn't use our equipment to make production runs, as the equipment is much too small. Our stills can be used to distill everything from rose hips and lavender to citrius oil. Farmers who have leftover grain can turn it into fuel for small equipment using distillation equipment.Įssential oils distillation is another popular use for our equipment. However, it is important to keep in mind that alcohol can only be legally distilled with the proper permits.įuel alcohol is useful outside of just survival situations. In addition to potentially saving your life in an SHTF event, these items could also be used to trade for other goods and services. Simple, small-scale distillation equipment can be used to manufacture valuable survival commodities such as purified water, fuel alcohol, and antiseptic, and more. First, distillation equipment is an important piece of survival gear. There are many reasons one might want to own a still.
