Dewalt DW788 20″ Variable-Speed Scroll Saw

Useful for cutting intricate curves in cases where a jigsaw or coping saw is not appropriate. It is capable of creating curves with edges. It is somewhat similar to a band saw, but unlike band saws, in which the saw blade is a continuous loop, scroll saws blade allow to make inside cuts.

  • Specifications:

  • Safety:
    • Never loosen the tension on the blade while the machine is on.
  • Usage:
    • Setting the Blade Tension:
      • The Blade Tensioning Lever tightens to the left, loosens to the right. This should NEVER be adjusted while the machine is running. Tensioning a blade should leave it taught, but some side to side flex.
        • If you often break the blade while cutting, the blade is most likely over tensioned.
        • If your cuts are not coming out straight or square, most likely the blade is too loose (or you’re forcing the material to hard into it).
    • Material Hold-Down:
      • A thumbscrew to the left of the blade allows adjustability of the material hold-down. Set it so that it is high up enough to sit right on top of your material. It does not have to sit tightly. This keeps your material from kicking up at you, and also provides a guard between your fingers and the blade.
    • Cutting Speed:
      • High speeds for soft woods
      • Medium speeds for plastics, harder woods, and thin materials
      • Slow speeds for metals and very thin materials
    • Sawing:
      • Hold the material pressed firmly against the table. Always feed the material toward the blade.
      • Feed the material fast enough to allow the blade to cut, but do not force the material into the blade.
    • Fretwork: (making inside cutouts within a material)
      • To fit the blade within the material, you must drill a hole large enough to fit the scroll saw blade into.
      • While the machine is off loosen the tension on the blade by moving the tension lever to the right. Loosen the top thumbscrew of the blade clamp. This will free the top of the blade while the bottom of the blade will still be clamped into place.
      • Thread the blade through the pilot hole.
        • The top arm of the scroll saw lifts up to allow easier access to the blade.
      • Re-tension the blade, and you are ready to make inside cuts within the material.
