Default need steel or AL shafts about 1" long, 1/2" diameter, with about a 3/8" hole bored in center
I looked through McMaster, found SAE 841 bronze sleeve bearings for $.62
each part number 6391k178. They have the same thing in steel, just not
quite the right wall thickness.

How easy is bronze to drill, compared to aluminum? Harder ? Harder than
steel ?
Thanks !
