In a guideboat, the oars are pinned to plates which are mounted with pins that fit in the oarlock. I have a new set of oarlocks, and a pin is used through one side plate, then through the oar loom, and into the opposite side plate, capturing the oar. In the new set, these pins are a loose fit through the side plates. Either the side plates or the oar must be a tight fit with the capturing pin. Should this pin be a tight fit in the plates and loose through the oar, or loose in the plates and tight in the oar?
