I usually do exactly what you say with only 2 hands. I also do use my legs a bit to steady and lift the wheel a bit. But my spacers will stay on the rim as long as you don't bump them too much...
I think you just get the hand of it after you do it a few times..... I also find a rubber mallet works well for getting that axle thru!
