I also read a post where a guy soaks antler in tepid water for a month or so which will soften the Pith considerably. Pull antler from water and simply force onto tang. Apparently the soaking procedure makes the Pith soft and yielding like a sponge. So it will displace itself as it is forced over tang. He then described clamping the horn in place as per normal gluing instructions, Except he leaves the clamps on for a couple weeks. This allows the pith or marrow to dry and make a postive grip on the tang.....No glues needed. Hope this helps. He did recommend to be ready for the stink when the antler is pulled from the water.....I have sanded antler so I know that smell........Cheers, Darren
