A 5-gallon can that has contained automobile oil is easily found and a hot lye bath will remove all traces of the oil. The lye solution is placed in the can and raised to the boiling point. It is then poured out and the can is rinsed with hot water.
Fig. 96.
The top of the can is removed and a strong handle fixed to the can. A small nipple of tin is soldered to the side of the can, near the bottom. This nipple is simply a flat piece of tin rolled into a cylindrical shape and of a suitable size so that a piece of rubber hose may be fitted tightly over it.
A second nipple of the same size should be made for the spray nozzle. The spray nozzle is made from a shoe paste or salve box. A number of fine holes are punched in the box lid and the tin pipe or nipple is soldered in a hole made for it in the bottom of the box.
A wire hook is provided at the rim of the pail to hold the spray nozzle in place when it is not desired to have the water run out of it.
It will be found convenient to have a double pulley and rope rigged to hoist the pail to a convenient height after filling.
The Match Box.—The match box is made of two cigarette boxes, one for good matches and the other for burned matches. These boxes are of ample size to hold the paper drawer of a large box of parlor matches.
