  1. Mark the finished dimension and identify the waste side.
  2. Set the guide using the actual blade-to-base offset; test on scrap.
  3. Support both sides of the cut without trapping the blade.
  4. Make the guided cut and verify size and squareness before repeating.

Tradeoff: Portable and accessible; guide setup adds time.

Track saw

  1. Lay the sheet on a stable supported cutting surface.
  2. Align the rail's verified cut reference with the waste side.
  3. Set depth and use the rail according to the saw instructions.
  4. Check the first panel before cutting its matching parts.

Compare 2 methods

Glue two full panels

  1. Choose the layer arrangement and recalculate internal depth if necessary.
  2. Dry-fit both layers and check alignment.
  3. Apply adhesive and clamp evenly on a flat reference.
