I’ll add my improvement to this thread. I have a few different holes drilled into the block that allows me to change out the pin gauge size to match the wheel bore diameter. Using a properly sized pin gauge makes for less slop and gives you a more accurate reading of the wheel roundness.

OOBigFish, What size Pin gage do you have for an AWANA wheel?

Never used Awana wheels. I use .096 through .0985 pin gauges for BSA wheels.

Did you ever get a BSA wheel bore to go over a pin gage larger then .0965 without intentionally doing something to the bore?

Yes, the typical sizes I find are in the range specified. 97-98 being most prevalent.
