    • Match the bit’s diameter with the width of the mortise hole
    • If you don’t have a drill press, consider stepping down a size to allow for less precision
    • Beginning with each end of the hole, chisel inward from the ends
    • Upon finishing the ends, work your way towards the middle
    • The direction of the grain and hardness of the wood species will determine how easily chisel inserts into the lumber
    • Clean the inside of the mortise hole and smoothen out any high points by using a combination of sandpaper and wood files
    • Upon completing this step, your mortise hole will be ready for a dry fit
