First time using a dado stack, and having a problem with chipout on the trailing surface, at the top of the dado. The leading surface is nice and crisp at the cut edges. It’s a Vicuti 8” stack, and the dado is 3/4 x 3/4. First try was with birch plywood, then I bought some Aspen hardwood. This is for some cabinet drawers. I get the same chipout with either wood. I’m using a box joint jig that I made. Holding the wood flat against the front of the sled. Tried painters tape, and scoring a line with a razor at the depth of the cut, neither worked. The slot in the front piece of the sled is a little higher than my depth of cut, could this be the issue? I also tried just doing a 1/4” deep cut, same chipout, both with and across the grain of the wood. Any tips or tricks are much appreciated! |
| Absolutely use a spoil board, or two to sandwich the workpiece. Never hurts to clean any pitch off the dado stack and check to make sure it is sharp. Make sure the jig doesn't wiggle in the miter slot, if it does either fix it (some runners have easy adjustments) or just load it consistently to the right or left. Good luck! |
Turns out, it was a different elephant.
