I’d like to see Bearing Flats offered in larger “sheets” that can be cut down as needed. The size should be around 5x5 (holes), though larger sizes could be useful too.
They should be strong enough that they can be used as a single block without accidentally snapping apart, but designed so they can be separated without damage using a knife or thin-kerfed saw.
This would mostly be a convenience product, but it could definitely simplify (and probably lighten) many gearbox designs.
Cheers,
