Instruction
1. Carry a pipe to the turner in order that he cut off a piece of a pipe of necessary length, chamfered and ottortsevat edges.
2. Manufacture the adapter which will connect a pipe to a cover of the device and knot of selection of distillate. On the one hand the adapter has to be inserted densely into a pipe, and on the other hand it has to have a carving a step of 1.5-2 mm.
3. Make basic washers for a nozzle. Their diameter has to provide dense landing in a pipe, and their openings to have diameter of 3-4 millimeters. Insert one washer on the one side of a pipe. In the place of accession of a pipe to a cube solder the adapter, previously having smoothed out the place of soldering. Insert the zaluzhenny adapter into a pipe and heat the place of soldering by the gas burner.
4. Make nozzles for a column. Fill up nozzles in a pipe and stir up a pipe for uniform laying of nozzles. The pipe has to be filled to top with nozzles.
5. Insert into a pipe a basic washer for a nozzle. After that insert a zaluzhenny face of selection, heat the place of accustoming to drinking. Dress a heat insulator on a pipe.
6. Start dismantling of a thermos. Smooth out a thermos bottom an emery paper and you zaludit the smoothed-out place. Make of tin a bracket, and of a steel wire – a loop. Bring loops to an opening of a bracket and twist them flat-nose pliers.
7. Clamp the free end of a wire in a vice and beat to a wall. Both hands take a thermos and sharply pull. The bottom of a thermos has to fly.
8. Grind a welding seam which connects a cover and a flask of a thermos on perimeter. This procedure needs to be finished when between a cover and a flask the small gap on all perimeter does not appear. Take an internal flask from external.
9. Make a dephlegmator. For this purpose remove a bottom and a vacuum cover. In an internal flask drill an opening on the center of the back party of a flask to provide air access inside. Smooth out and zaludit the place of an opening and insert into it a pipe. Solder a pipe in an opening. On the center of a bottom of a thermos drill one more opening and dress a bottom on a flask. Propayayte tube and bottom of a thermos.
10. Zaludite mouth of a thermos and knot of selection. Insert knot of selection into a mouth and solder it. For tubes of branch and a supply of the cooling water make openings at the top of and in the bottom of an external flask of a thermos. Insert tubes and a propayayta of the place of joints. For the sleeve of the thermometer drill an opening in knot of selection of distillate. In the sleeve drill an opening diameter of the probe of the thermometer, insert the sleeve and knot of selection.
11. Wash out all places of soldering by means of solution of baking soda in water. Fasten a dephlegmator to a column and wash out under a water jet.
