Hi, Biotech1

So what's the, "real crappy on the other..." values.

Not to much info in your post to work with, Is it Backlash, Flex.

Thanks, Chip

Mill bit is too small, it's walking around one way on the inside cut and the other way on the outside cut. Use as big a mill as possible when you can.
