gotcha. i should have clarified my post more, instead of such a short version.
i cut the kerf to a particular length, the wedge to a particular length and mark the "bottom" point on the wedge, so that the wedge will be about 1/8" or 3/16" from bottoming IF the line on the wedge drove flush with the top of the handle.. i hammer the wedge until it WILL NOT go further and the wedge has mangled and split(usually). i am not worried about bottoming the wedge, and the top 1/4 of my wedge is cut too thick to enter the eye. the hickory will only compress so much, and reaching that point is my objective, before the wedge bottoms.
i consider that fully seated. wont go deeper because of wedge action, not because its bottomed in the kerf. i agree that if the wedge bottomed before stopping from wedging action, then its not seated properly. i had that happen a couple times early in my hanging career. i developed my kerf and wedge design from hanging, and only hanging. i try to get the two to coincide as closely as possible to the bottom without actually "bottoming" out. thats what i mean when saying "seating and bottoming" getting the wedge as close to the bottom as possible without stopping from interference.
my point originally is that i personally want the wedge so tight, that it wont move a week later if i pounded on it more. luckily, i havent had anything work loose since about the 5th hang or so. took some trial and error to figure out what worked for me personally. the most important factor, i think, was deciding to cut my own wedges.. instead of using the supplied wedges most of the time. since then, no problems. i did have a couple stock wedges back out a smidge after heavy use in the beginning. they were to steeply cut. i cut them more acute, but thicker. the wedge does not taper to a point, but starts at about a kerf width, and fattens slightly in the first 3/16", then tapers in a fairly acute angle. much more acute than stock wedge. somewhere in between a stock wedge and a window/door shimming type wedge.
im sure your method works fine too. i was just curious, as i didnt understand what was happening. i also have never made a handle out of lumber i would consider "green" in any regard. not a dig, just havent done it personally. always up for learning other techniques, thanks for explaining.
