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 veryweak at these points and considerable care is necessary in handling inorder that some accident does not break them apart before it is time tobend. If one breaks it is not a very serious matter, only the corner willnot have quite such a neat appearance. In practise we find it best to bendeach cut as soon as finished and roughly fasten with solder. When all. Fig. 159. Frame Secured Around Wooden Form. Note Re-inforcement in One Corner three bends have been completed, place within it a wooden form as shownin figure 159. Except for the corners being cut ofif (to allow for solder-ing) the edges of form should be perfectly rectangular and fit secure quite firmly with stout twine. After all corners are truedup with the board, apply the permanent solder. Melt solder from any TROPICAL AQUAEIUM FISHES 215 corner that does not stand true without forcing. In the upper-right cor-ner of our illustration will be noted a right-angle flange reinforcement,cut from a flat piece of 1/16-inch brass. It is advisable to use add greatly to the strength and actually make the work of solder-ing easier. After preparing the surfaces with solder-flux it is only neces-sary to place solder on the frame, lay the flange on top of it and applytorch beneath. When solder melts, press flange down and into exactposition with a small stick of wood. It
