Very nice HF Rich!
Also nice of your wife to let you buy the Monster.
I can see how the hole needs to be bigger for the 3/4" bar, but it is easy to make smaller and specially shaped bars to fit the smaller holes.
See the attached pic of one I made for my Monster, the cutter is 3/16" metal lathe shaped to a round scraper. Works perfectly and goes all the way to the edge under a wide rim.
