Leading edge work borders on being more of an art form than most of what we do when building.
There is no doubt you really need to look at your work as you go. I usually start with the razor plane and do some beveling as mentioned above.
I have also made some sanding bars by cutting open pvc tubing and gluing sandpaper on the inside radius/surface . It seems a little strange using it at first, but it adds another useful tool to the quiver
