Router-table mortise maker
This double stopblock with connecting safety fence ensures identical mortises.
This double stopblock with connecting safety fence ensures identical mortises. Plunge the workpiece down along the edge of the right-hand stopblock using a pushpad, as shown above, to start the mortise. Then feed the workpiece to the left through the cut until it bumps the left-hand stopblock. Finally, raise the workpiece along the edge of the left-hand stopblock.
To center the mortise on the workpiece end, mount stopblocks on your router-table fence, as shown below. To figure the spacing between stops, add the workpiece width to the length of the mortise, and subtract the distance of the mortise from one edge.
