The write up is good and describes the process well. I would just add that I found removing the drill bit from the cutter and spraying WD40 in to keep it lubricated worked much better, also I didn't need to use the hammer function just applied light pressure then let the cutter do its business.
In my case I removed the first and last baffles and kept the large 8 holed center baffle.
