Do It with Tools and Machines 



In upper right hand cor-

Car rails wear quickly at a spot slightly 

 ground out by slipping wheels, but with this 

 portable grinder the rail's surface is quickly 

 smoothed to the level of the depression 



Below, a machine which punches or blanks un- 

 cured rubber stock from the rubber calendars, 

 and which is to be used to manufacture rub- 

 ber shoe heels, water bottles and other articles 



Nothing is more annoying to 

 the steam fitter than to have 

 a pipe wrench slip when 

 turning a pipe. Above, a 

 large wrench which a man 

 can trust to hold his weight
