How to Make an Alcohol Lamp and 

 Blow-Torch from an Oil- Can 



THE spout of the can is cut off so 

 that about 232 '"■ remain above 

 the thread. This portion of the tube 

 is then filled with a wick the same as for 

 ..^^ the ordinary torch. A 



piece of brass tubing, 

 bent as shown and 

 soldered to one side of 

 the spout, pro- 

 vides a means of 

 attaching a 

 small rubber 

 tube for a blow- 

 pipe. Wood or 

 denatured alco- 

 hol is used for 

 the fuel. A torch 

 made up in this 

 manner can be 

 used for solder- 

 ing in very diffi- 

 cult places as the flame may be easily 

 directed into places that cannot be 

 reached with a soldering iron or with the 

 flame from the ordinary kind of alcohol 

 lamp. — L.wvRENCE V. Greenhaus.

Two Good Calking Compounds 

 for Boats 



THE best calking compound used 

 is made of equal parts, by measure, 

 of white lead ground in linseed oil ancl 

 paraffin. Put the white lead in an iron 

 pot and heat it, then stir in the paratifin. 

 While still hot appl\- to the seams with a 

 seam brush. This mi.xture will make any 

 boat water-tight and will not contract 

 and fall out of the seams as some com- 

 pounds do. 



Another good compound is one part 

 Portland cement to si.x parts coal-t.ir. 

 Boil and brush over the entire boat 

 bottom while hot. This mi.xture is 

 generally used as an extra heavy calking 

 for old boats. — J. J. Sturmer. 



Making Automobile Wheels 

 Track Correctly 



MOTORISTS are often puzzled be^ 

 cause one tire will wear out faster 

 than the others and give considerably 

 less than the required mileage. General- 

 ly the trouble is always experienced with 

 the same wheel and the tread appears to 

 have been ground away by a coarse 

 emery wheel. If this condition exists, 

 it is time to check the alinement of the 

 wheels to make sure they track correctly. 

 The recently invented device illustrated 

 makes it possible to do this in an accurate 

 manner. 



It consists of a base-piece of pipe 

 resting on cast-iron feet or pads and 

 having sliding heads in the pillars at

 RULER " 



The base-piece rests on cast-iron pillars with 

 sliding heads which are graduated rulers 



each end. These are graduated, one 

 of the rulers having a vertical move- 

 ment whereas the horizontal one can be 

 moved laterally and both can be set 

 when the measurements have been as-
