Copper still construction is not as difficult as many think it to be in terms of technique. However, to avoid injuries, one needs to be careful around this work. The melting of copper requires the use of touch tools to mold this material and make different structures. So it is necessary to use gloves and wear protective eye-wear. These precautions will protect your eyes, hands from injury. There are other items such as bolts and rivets, and you will have to weld together the pieces.
Copper stills that are a piece of distillation methods must be carefully put together. Leakages must not take place, and development must be defined so that the entire apparatus runs evenly. It would help if you had all your measurements accurately documented and completed. Any spaces that could have leakages must have airtight restraining or substances filled in to limit this.
