It is a JD2 Model 3 tube bender that I have bought: http://www.jd2.com/shop/ and I have made a 100 X 100 steel box section post welded to a 750 X 500 X 10 steel chequer plate. I intended to use 10, 10mm dia Rawl bolts to fix it to the floor ..... after all until I can afford and justify a hydraulic power conversion kit I shall be swinging upon 0.9 mtr long handle to form bends in 16 -25 mm tubing and a 1.8 mtr long handle for 40 and 50 mm chrome alloy steel tubing. I don't have a forklift, and the most that the post could be hit with is either the sack barrow, Pedi-van or Sammy cycling in too fast through the workshop doors. It looks like an SDS drill and through bolts will be on the cards first thing Tuesday morning, However, thinking about it the drill produced dust that did come out of the 6mm pilot holes that I managed to get into the floor showing a dark grey colouring rather than the sandy grey concrete colour I was expecting. So tomorrow morning I shall pass a magnet over this dust just to check if I have hit shallow placed re-bars.
