. Goldfish varieties and tropical aquarium fishes; a complete guide to aquaria and related subjects. Aquariums; Goldfish. AQUARIUM CONSTRUCTION 213 Frame Construction. A hack-saw with fine teeth for metal-work- ing- will be needed to cut the proper lengths of angle metal. After carefully 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 beveling the two ends and preparing right-angle cuts at three points, as shown Fig. 199. Cut, Preparatory to Bending Angle Brass in above figure, the whole can be bent into a frame that will pro- duce very neat corners and make soldering easy. The right-angle cuts should be finished with a square file and carried 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 practice 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 below. Except for the corners being cut off (to allow for. Fig. 200. Frame Secured on Wooden Form Note Reinforcement in Upper Right Corner soldering), the edges of form should be perfectly rectangular and fit closely. Now secure quite firmly with stout twine. After all cor- ners are trued up with the board, apply the permanent solder. Melt.
