Frame Construction. A hack-saw with fine teeth for metal-work- 

 ing will be needed to cut the proper lengths of angle metal. After care- 

 fully determining proportions desired, cut the four uprights and then the 

 material for top and bottom frames. If working in brass the latter should

each be left in one piece. By accurately bevelling the two ends and prepar- 

 ing right-angle cuts at three points as shown in figure 158, the whole can be 

 bent into a frame that will produce very neat corners and make soldering 

 easy. The right-angle cuts should be finished with a square file and car- 

 ried within about 1/32 inch of going through. This leaves the bar very 

 weak at these points and considerable care is necessary in handling in 

 order that some accident does not break them apart before it is time to 

 bend. If one breaks it is not a very serious matter, only the corner will 

 not have quite such a neat appearance. In practise we find it best to bend 

 each cut as soon as finished and roughly fasten with solder. When all

three bends have been completed, place within it a wooden form as shown 

 in figure 159. Except for the corners being cut ofif (to allow for solder- 

 ing) the edges of form should be perfectly rectangular and fit closely. 

 Now secure quite firmly with stout twine. After all corners are trued 

 up with the board, apply the permanent solder. Melt solder from any
