Yes, I believe Bob would thread the hole(s) in the tang and turn a size 8-32 screw into the hole. Then cut off the screw so that about a 3/32-1/8" stub would protrude on each side. Then in the drilled holes in the slabs he would enlarge the bottoms fo the holes, so that they were wider at the bottom, with a small round moto tool burr. Then assemble the handle with epoxy and the glue would attach to the screws and fill in the enlarged holes in the slabs and anchor the handles in place. If this in not clear, ask for more details, OK?
