Show WATER STILL IS BIG NECESSITY FOR SHOP Any Source of Low-Pressure Steam Will Work Weil. A water still is a necessity In auto repair shops and often a convenience in the home. A simple and yet efficient effi-cient still can be made and used In any place where a source of low-pressure steam can be obtained ; in other places the hot-water tanks can be converted con-verted Into steam generators with but slight alterations. In the latter case a steam line is Inserted In-serted In the top of the water tank with a low-pressure steam gauge and 1 1 COLO WW -tArTY VW.V1 ULCT A Q) low pwissuat P-RI" ' TANK OPPt ,!

The water is kept below the line shown In the Illustration, its level being indicated on the water gauge at the side. The still Itself consists of a ten-gallon oil can with the top removed and a copper coll. The steam Is led through the coll, where It condenses and the distilled water flows out of the end of the coll, which projects from the tank near the bottom. Cooling Cool-ing water Is led Into the bottom of the tank and an overflow pipe Is soldered to the tank near the top. Any source of low-pressure steam will work well. Steam-heating systems sys-tems and steam-pressure cookers properly prop-erly equipped with valves and gauge? may safely be used in eonjunctioi' with this still. John H.
