I am making small sliding lid jewelry boxes for Orange County Toymakers charity. Using a solid block 2" x 3" x 1 1/2", I hog out the inside and cut for a dovetail sliding lid. My problem is that the 1/2" up-cut spiral bit, as I run into the corners sometimes grabs the grain in two of the corners and drags the bit/router body outside the intended cut line. I am moving the workpiece upside down counter clockwise within my jig, so against the rotation direction of the flutes. I tried once to do a climb cut, but got the work taken out of my hands an flung across the shop, so I am leery of that approach.
Here are pics of my jig, the workpiece before routing, and two with damaged corners.
Can anyone tell me how to avoid that corner tear-out?
