Rear Wheel Boss Hole Size

I have just received Kits 4 & 5 for building the rear wheels and find the sintered bronze bearings cannot fit the boss's bored hole.
Rough sizes are:
Shaft diam: 3/4"
Bronze bearing outer diam: 15/16"
Bronze bearing inner diam: 3/4"
Boss bored centre hole diam: 13/16".

In other words it looks like the boss has not been bored out enough to the 15/16" of the bearing.
Am I missing something or should I get on to STW.
Unfortunately I live in Florida, where it is sunny and gorgeous right now.
