  1. I actually made a mistake. I supply the Big Blu with full tank pressure (175 PSI) through a 1" 200 PSI rated jack hammer air hose, but the pressure is knocked down to 150 PSI by the regulator, filter, oiler on the hammer. The KA is running on 175PSI though. I had also thought about the blows per minute, and hammer controll issues, as far as BPM Big Blu claims 0-225 on the 155, and on the KA it depends on how fast you are with your foot, but I would guess that it would be hard to even keep it at 180 BPM. As far as controll.. I don't really know that we can devise a test to measure controll because that all really depends on the operator expierience, condition of the machine, temperature of the machine, etc. I think Mike-hr came up with a great full power test, but as for controll, I am willing to accept the educated opinion of other Power Hamer operators. I know that I have no problems drawing 1/4" stock to a fine point with any of my hammers, or delivering a single light tap, or full force blow, which is a little tricky with the mechanical hammers but a breeze with the air hammers (pun intended!!)

    well this is the kind of response we thought we would get. that is the reason we recorded the video and posted it to the you tube. 175 psi?...i wish we had that in the shop..we're pretty sure jose's is a mk3(one of the old qc hammers..
  2. looks good..its just your syle of wing. i like the base.
