  • Begin with each end of the hole and 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 the 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.
