Dear Steven

For my two penn'orth I suggest reducing the pass depth to 3mm or so and increase the RPM to say 19K. Checking chipload calculators would say these (3mm and 19K) are out of range and may burn the cutter. But as you are using this 'Quarter Sawn' (vertical grain cedar board) soft cedar you could give it a go.

Have a look at the end grain of your boards and see if you have any tangential sawn ones and give one of those a try and compare it to the quarter sawn. I'm sure you will see a difference.

Anyway I'll watch with interest to see how ir works out for you.

Sincerely and in good faith
Martin

PS Check the cutter is still in good nick after all this messing about.
