Trouble may, however,result from a failure to allow a proper amount for expansionand contraction, but as this information can be furnished to. Oxy-Acetylene Welding—Motor Frame with Hole BetweenLugs Built Up with New Metal an operator in tabular form for different kinds of metal theelement of individual judgment in this matter may be largelyeliminated. Practically all the metals found in electric rail-way equipment may be welded, built up or cut off, the oxy-acetylene flame being especially adaptable to the latter. The cutting of metal can be handled very quickly by theprocess at a very low cost, and the small working space re-quired makes it particularly advantageous in places where ahack saw could not be used. For example, Mr. Clark recentlyfound it necessary to trim off portions of the platform kneeson certain cars in order to provide proper wheel ordinary conditions it would have been necessary toremove the platform knees from the car, but with the plantavailable the work was done with the platform knees inplace, thus avoiding a considerable item of expense on thisscore alone
