gouging rods

[Feet 'n Inches]

30 years back, IIRC, there seemed to be only two easily accessible options, gouge with oxy/acetylene using a special nozzle or gouging rods. Rods were quicker in removing unwanted materials but produced clouds of smoke not to mention showering the area with hot metal fragmenrts . . . not the best of things in a building. If memory serves, I used to select a current that was within the range of the next size-up rod to the one I was using. I spent quite a bit of time in those days out on site repairing cracks in digger buckets, earth moving equipment and so on. Gouging rods made life pretty easy under those circumstances.
