Turners have long used thick and thin superGlue to stabilize workpieces, especially bowls. I have found that superglue is also good for stabilizing knots, cracks and flaws in regular milled lumber. I simply fill cracks in lumber and loose knots with regular superglue, and give it a shot of spray-type rapid cure before I begin working with it. I have “saved” quite a few pieces of lumber which might otherwise have been discarded as unworkable.
