I drilled a hole in the center, ¼ inch wider than the shaft is. There will be an eighth of an inch between the shaft and the wheel on each side.
Each wheel has flanges that are glued to it, and there are spacers to push the flanges out to the sides a little and make the wheels really steady. I cut the flanges to size and drilled holes in them to accept the shaft and bearings.
The bearings are pressed in to the wooden flanges and just held there by friction. I used a 2 inch forstner bit to cut the hole for the 2 inch outer diameter bearing. The bearing can be easily pushed through the hole with my fingers. It’s a nice fit once you line it up, but it just slides right through the hole.
