PSA: I blamed my tools for rough cuts until this one job
I always thought if the finish was off, it had to be a dull or cheap end mill, you know? But on a recent run of stainless steel parts, even fresh tools gave me chatter. I mean, I was ready to order new cutters, but then I checked the workholding. The part had a tiny bit of play in the vise jaws. Adding some rubber pads and cranking it down just right solved everything. Maybe it's just me, but now I look at the fixture first before anything else.
