As I understand it, they should be positioned to lower the blade 1/8" to
1/4" below its free position to help it resist twisting in the cut. It
concerns me that the blade back rests on and rubs the flange rather than a
separate ball bearing. Does anyone have experience with operating and
maintaining a bandsaw lumber mill?


I don't , but from what I've seen you post about it would seem
trivial for you to design a guide with the features you want ... Use
that basic design you posted the link to , but replace the flange with a
ball bearing . I'm thinking something like a scaled up 4x6 guide with 2
bearings per side in a sleeve roller and a back bearing , single but
also sleeved . Maybe use 4140 for the rollers .

Once I *know* what I want I can machine it, but it appears I don't
understand the subtleties of making a sawmill bandsaw blade continue to cut
straight as it begins to dull.

Neither do they:
