This roof is really starting to take shape!!

What happens here

Select a large wooden beam that requires custom modification, such as a floor joist or a roof rafter. Use a tape measure and pencil to accurately mark the specific locations for cuts or notches. Employ a circular saw to make multiple crosscuts (kerfs) along the marked lines where material needs to be removed. These cuts should be made carefully, stopping at the intended depth of the notch. Follow up by using a reciprocating saw to cut out the wood between the kerfs, effectively creating a clean notch or dado joint in the beam. This precise notching allows the beam to sit flush or interlock with other structural components, ensuring a strong and seamless connection.

Goal: Custom cut and notch wooden beams for specific structural connections.

Tools and materials

  • Circular Saw DeWalt — Making straight crosscuts and initial kerfs for notching
  • Hearing Protection — Protecting ears from the loud noise of power saws
  • Pencil — Marking precise cut and notch lines on the lumber
  • Reciprocating Saw DeWalt — Finishing cuts and removing waste material from notches
  • Safety Glasses — Protecting eyes from sawdust and flying debris during cutting
  • Safety Gloves — Protecting hands and improving grip while handling wood and operating tools
  • Tape Measure — Accurately measuring dimensions and marking cut lines
  • Large Wooden Beam — A structural lumber piece (e.g., joist, rafter) requiring custom cuts and notches
