I’m using a router sled to flatten end grain cutting boards, and cannot figure out why I’m left with a horrible finish. I’d love some feedback on what I’m doing wrong, or what I can do to improve… I’ve read so many posts about using a router sled to effectively flatten surfaces like this.
The sled functions well and the boards do come out flat. The problem is it appears that the bit is roughing or tearing up the end grain significantly (I’m not sure what to call this issue… tearout? fuzz?). See photos below. I’ve tried varying spindle speed and also the rate that I’m feeding the router over the board. Saw this same issue when routing pockets on the bottom of the board (not using the sled, following an edge guide)
I’m using a Ridgid 2hp router with a 1.5” Freud bit. Had similar issues with a 1/2” bit. Both 1/2” shank.
The wood is leftover butcher block countertop from Ikea. Beechwood. I haven’t had other issues working with it in table saw, circular saw, router to clean up edge of countertop, sanding, etc.
Other thoughts: the chips that come off are quite small and gritty almost like cornmeal. The surface can eventually be cleaned up with a combo of a cabinet scraper and a ton of sanding… essentially have to remove enough material to get down to clean end grain.
Any input is much appreciated!
