I have been trying to get an old CECO (Chambersburg )hammer (BLOWMATIC) erected.I have been able to get the machine on its feet, but struggling to make it work.The solenoid controlled Pneumatic system was not effective and the valve was refusing to move and the hammer kept swinging with no controls.i decided to set up a lever system pedal operated to make the valve work.I have fabricated all the parts and put them in place.I am not sure it will work.Look forward to any tips on this.
