I recently purchased a pro planer and replaced and sharpened the blades. All went well but after replacing the blades there is a slight ripple visible to the eye. It is not deep but noticable and will not sand out in just a stroke or too. Any suggestion as why I may be getting this result Believe the blades are set know good and don't about in or out feed potential causes if it is that at all.
Thanks,
Tom
