I have made a couple different ones and didn't really care for the threaded inserts from the hardware store. The handles I made are a little wider than most so it just didn't look or feel right. Instead I use a 3/8th - 16 UNC screw and glue it into the bottom of the tap handle. If you leave about 1/2" stuck out of the bottom then use a ferrule (I use this one
) as a female-female connection between the handle and the tap. Sorry no good pictures of the actual connection, hopefully it makes sense. On my setup it just looks a little nicer and makes the handles feel a little more solid.
I have a tendency to never take pictures until projects are almost done, just get too caught up in the process. Here is the one on the left before it got painted.
