Has anyone ever replaced the thin seals that go under the flat washers for the trunnion with a like sized O-ring? Those seals seem to crack and break after no time at all. I have a selection of O-rings and the 1/8" thickness, 1-3/16" ID x 1-7/16" OD fits great. Anyone see a downside to this? Thanks, Kurt Oblinger Redondo Beach, Ca. (too many projects)
