The cutter I ground is a single lip straight flute. Like an engraving
cutter, only straight sided. I did that to get max strength since I want to
be able to cut 1/8" ply in a single pass. I tried a sprial flute cutter and
they break real quick under those loads. I am astounded how strong this
single lip cutter is, and it cuts a real clean slot in pine. Ive even
dragged it along the work a couple times when I forgot to program a spindle
on command.

I tried moving faster than 15ipm and the cut path seems to have a 'swim'
particularly on the spots where I plunge in to start a new cut.

I expect to use a 1/8" cutter for most of the work, only using the 1/16 when
I need to get into sharp corners.

Thanks for all the suggestions.
