Trying to design the dropouts for a QS205 and came across this issue on the disc side axle. You see, the way it's machined I don't see how you can clamp a flat plate with the nut.
If you clamp like A, you have good bearing surface but the clamp surface is small and unstable. If you do it like B it's stable clamping but poor bearing
Do you have to use a special washer for A? do you "key" the dropout with extra material in the back? Do you grind the top part in B to increase bearing and clamp surface like the freewheel side?
Hopefully the schematic makes sense
