NARROWING BEARINGS
When I need to narrow a set of rod bearings, I have bucks that I’ve turned to the size of the crank pin. Then, I wrap a single layer of masking tape around them to protect the bearing. I hold the bearing to the spud with a couple hose clamps, attached end to end. Using 2 seems to snug up better than as a single one. If the buck is a specific width, it’s easy to use that in conjunction with where the tool bit touches it, to get the bearing width dead on.
