Advice on Fly Cutter needed

I surfaced my face plate with 1/2in end mill including the finish pass. It came out great. The base plate is 24in square and is one piece T-6000 Al. It was very flat and co planar so not much cutting. Now I need to get the edges and as much of the back ac I can without flipping the gantry for now.

What is the the best way to go about this. In particular, do I retouch off the fly cutter and just act like I hadn’t done anything before.

I have the Langmuir fly cutter.

Looking for best way togo at this. Thanks in advance.


make sure your head is trammed/ square, if the tool isnt perpendicular to the table you will get ridges especially with a large diameter tool
