To grind the openings in the frame I have used this sanding band stuff:

13 mm, #60 and finally #120
Be aware that these grinders try to run over the surface (some force in rotation direction) and initial positioning is difficult because of that.
You should mark the desired position and try to keep that as good as you can. My openings are approx. 10° or 15° away from it’s desired position left and right, but they are approx. 180° opposite to each other, which will allow to remove the shell from the frame without tilting them.
I have no experience yet if that has any affect to the bike, but expect that there will be none 😉
As the lower bearing shell was loose in the frame by any reason, I’ve glued that in, but I was told that I have used the wrong glue.
Loctite 638 is the right stuff for that purpose and I have to do that again after removing the shell and cleaning the stuff from the other glue.
A small bottle (20 ml) of Loctite 638 costs 10,- Euros over here.
Well, finally it will work and we can go to Norway 😉
Cheers, Michael
