Is your chassis held together entirely with T-slots? We thought those would not be strong enough, so we use wood glue for everything. It probably helps that you are using 1/4" plywood, rather than 3/16".

How small is "a hair smaller" for wood?
Press fits in metal are pretty precise. 0.001" smaller than the bearing is a light/ medium fit, whereas 0.002" is a heavy press fit, for the usual FRC bearings. Wood would be more forgiving on the size.
