W.Robertson Machine And Foundry Economy #2 Power Hacksaw with hydraulic lift had a cost of $80.00 in 1931. This saw was dry cutting with an electric motor drive.
Short clip of the Robertson Machine Economy 4x Power Hack Saw my Dad and I are starting to restore. After it sat for 50-60 years as a retired Navy machine, my Dad picked it up, so we had a bunch of grime and grease to clean out of the machine. After greasing and lubing it, he wired up the 3 phase power to it and it cranked right up! Stay tuned and I'll post more videos as we begin the restoration process!
