I’ve done a pretty good job of not cutting into my spoil board too badly, but I wanted to get some thoughts on approaches for face milling the top of the boards. The screws holding the board down are countersunk fairly deep, so it would seem that we can safely mill off a couple hundredths to get a fresh surface a few times before the board is spent.
I recently ordered a 1/4" three flute carbide end mill from mcmaster and the appropriate er11 collet to fit it (from amazon). The collet is not up to the standard of the Carbide3d supplied collet, but it will suffice for roughing work.
Any thoughts on how to approach milling this? I’m thinking of generating an stl file in SketchUp which is a flat plate .05" thick and slightly larger than 8" in width and height.
I’ve defined the 1/4" end mill in MeshCam and am eager to cut with it to see what speeds I can get in wood. Perhaps I’ll try a piece of scrap before I attack the spoil board. Can I get by with a roughing pass for face milling the surface, or will I need to do finishing passes? I’m assuming that I should be able to do everything with the 1/4" end mill.
