While cutting a biscuit slot, the biscuit jointer "walked" to the left and ruined the leg. Before I throw it the scrap pile, is there anything that you can suggest that can fix it. I can make it the back leg so that the screw-up is not noticeable as much. The rightmost pencil line shows where the slot was supposed to end; the left pencil mark shows where the bottom of the table is.
What can I do to prevent the biscuit jointer from sliding?
