Just saw an old post from chris where it seems he just drilled a hole and pounded it in
I've installed a fair number of these. My best advice is to experiment with different hole sizes in scrap first. Depending on how much taper there is to the shank and how soft your wood is you can sometimes get away with a single hole. In shanks that have a pronounced taper, you might need to drill a stepped hole. I usually let friction wedge the the metal in the hole, but some customers prefer epoxy in addition. Overkill, but that's fine.
