I am pretty sure I can use that to mold with and for a sleeve with UHDWPE (or the wood) and it should last.
Still trying to get a quote on bronze.
I think this will work better than two bearings, but not as well as multiple bearings.
The total cost, fabrication time, maintenance issues all favor the Bearing Sleeve method.
Also my calcs indicate less point stress, but the sleeve won't rotate as easily as unloaded bearings. . . I am not sure that I should care.
