FWIW, many years ago I redid some wood scales and used HW store epoxy only, they (4 knives) never came off that I know of. Ive been thinking of doing the 'dog bone' trick, too, and kinda like the look of 'pins'. My notion has been to epoxy one side down and use the blade holes as a guide to drill through, then epoxy on the other and come back through from the first.
