Discussion on “some notes on track bonding”

C. W. Ricker: The cost of applying bonds, which I have given, may be criticized as unduly low; it is intentionally very close, but it is attainable with compressed or expanded terminal bonds. The use of reliable hydraulic compressors might reduce the figures a little, but the amount would not be great, as the copper must be compressed rather slowly and the hydraulic machines are heavy and difficult to handle, so that the net saving of labor cost would be probably small, though the quality of work might be improved by their use.
