SPLITTING OUT AND ASSEMBLING 63 



lie flat under pressure, and largely nullify each other 

 when six of the strips come to be bound up together. 

 Also, it will be seen that further and very effective 

 opportunity for straightening the whole joint pre- 

 sents itself when the strips are glued up. 



In straightening over the flame, some considerable 

 charring of the woody fibre on the sides of the strip 

 excepting its enameled surface need not worry the 

 novice, as all this will plane away in the reduction to 

 final form and this is why we left the rectangular 

 strips somewhat larger than apparently was neces- 

 sary; but you should take good care that this outer 

 or rind surface is least directly exposed to the heat 

 and so is not injured, and you do not want the rec- 

 tangular strips left excessively large, else they will 

 not bend so readily when heated as there is more 

 wood for the heat to penetrate thoroughly. 



Occasionally the sudden deflection is compound 

 instead of simple; then it first should be reduced to 

 a simple deflection and straightened afterward, as 

 shown in the illustration (i, before remedying; 2, 

 first bending; 3, direction of final bending). And 

 here we should state that concerning the deviations
