Gero, Thanks!
LakeWorthB, I used a Yonico brand 1/4" 2 flute compression end-mill
madgrizzle, yes you did see that. I had a “tooth jump” event at the very start of the run. I had lubricated both chains previously and doing my best to keep the chain in plane on the out-feed side, but thinking about experimenting doing the same for the in-feed side.
