With a reasonably fast micro, eg Raspberry Pi4, and an ok camera attached
to it, plus a bunch of controlled motors and attached mechanisms, it's
feasible nowadays to make an active sharpener, to touch up the teeth while
the bandsaw is running. Feasible means possible to do; it doesn't mean
easy. It would be a project that could last a few years longer than
the several days of work your larger-bearings approach will take, and
could cost a couple of magnitudes more dollars, depending on how many
sawmills got wrecked during development.

================================

Feasible perhaps, also risible.

The blade maker suggested and sent me a short piece of blade to use to
design a cam that would guide a small cylindrical grinding stone along the
gullet path, one tooth space at a time. The stone could be any size up to
the gullet radius as long as the cam follower pin is the same. This reduces
the tooth grinder to a fairly simple Dremel attachment and the blade guide
to a slot with an index pin.
