Anyone here experienced with Magic Mill wheat grinder?

When my dad was alive he made bread with wheat flour he ground in the old wood version of the Magic Mill grinder from the 70s.  I brought it home the other day and it works fine, but on its finest setting the flour it makes is not very fine.  I can see how the coarse/fine adjuster could be modified to bring the grinding stones closer but I'm wondering if anyone else has had to do this.  Any advice would be greatly appreciated.

I have a Magic Mill with the steal blades. I have used it on corn and buckwheat as well as wheat.  I always get a nice smooth flour.

Did you try sifting out the fine stuff and running the courser stuff through again?
