Great photos, thanks for posting!
To get the blade to center properly in my slant I pull the exposed non-cutting edges up slightly while I tighten the head. Works every time.
Just received my 39C today in the mail from our own B&B member shyrlock. I tested your method of lifting the blade many times and found the blade aligned perfectly at the end of each tightening. Also tested many times just dropping in the blade, tightening and discovering it was way out of alignment almost every time. I can now see why so many folks have experienced this razor as a face shredder. Thank you so very much for this alignment tip.
