Not sure if the arbor press is easy to work with, but i dispute my creativity quotient in this regard; it was just simple this is a round hole, and this is the round peg that fits in it sort of thing..(except rectangular would be more fitting).
maybe, but you did it first and more importantly shared it with everyone. so props.
plus i always call the HMK swing an HMK swing so it's already in my lexicon.
