You are going to find that the axle nut will get loose and need tightening several times as the new axle stretches and the blades and spacers settle in. You need to check them at least every round you make by taping (hard) the individual blades with a hammer. Any not ringing are loose. I used to carry a 4 pound hammer and pipe wrench to beat them tight with the disc blade engaged in the dirt. After you get them seated well and the axles stretched, you should bend that keeper washer over. I wouldnt do it now as you will be tightening them several times before you get all the slack out. Using an impact might get them tighter than my old method of pipe wrench and shop hammer, but the advantage was, I could have them in the field and tighten on the spot.
If you are going to impact them, I would tighten, then go over each blade with a hammer making a firm hit from the back side, then try the impact again to see if you get some more turn. Repeat till the nut no longer moves. Striking the blade induces it to seat into the coupling spacer. They should all ring like a bell at the same octave when tightened.
