Who (screws simplest, not difficult!) with a coarse file (Metal Wood or cornea of the pharmacy, do not care!) and a little assembly work and release the 2 walls the honing run diagonally and thus the insertion times widened bottom, which can thus also cards mix with 62mm wide, as I now.
I can not confirm that the crank drops slightly. it is removable but not flying just assume not rotate when. The construction is stable and proven as with many manufacturers.
The special feature, the divisor of 90 to 100 mm is also located very accurately and is not labrig, but also strong and stable
