Scroll Saw Tips

1. Reverse-tooth blades leave clean edges on both top and bottom of plywood
2. Spray-adhesive your pattern to the wood; peel off after cutting
3. Drill entry holes for interior cuts; use a #60 drill bit for #5 blades
4. Stack-cutting multiple layers saves time on batch projects
5. Apply clear packing tape to the bottom of your wood to reduce tear-out

Example Calculations

1Fretwork Plaque (8" × 10")

Inputs

Pattern Size8" × 10"
Cut Length60 inches
BladeReverse Tooth #5
MaterialBaltic Birch Plywood

Result

Material0.56 ft²
Blades Needed1
Total Cost$1.07

8 × 10 = 80 sq in = 0.56 ft² of plywood. 60" of cuts / (40 ft × 12) per blade = ~1 blade.

210 Christmas Ornaments (4" × 4")

Inputs

Pattern Size4" × 4"
Patterns10
Cut Length/Pattern30 inches
MaterialBaltic Birch Plywood

Result

Material1.11 ft²
Blades Needed1
Total Cost$1.73

10 × (4 × 4) = 160 sq in = 1.11 ft². 300" total cuts / 480" per blade < 1, but round up to 1 blade.

Frequently Asked Questions

Q

How many scroll saw blades do I need?

A single #5 reverse-tooth blade cuts roughly 30–50 linear feet of plywood before dulling. For a project with 60 inches of total cuts per pattern, plan on 1–2 blades per pattern depending on material hardness.

  • Plywood: ~50 ft per blade (softest on blades)
  • Hardwood: ~35 ft per blade
  • Acrylic: ~30 ft per blade (generates heat)
  • Always keep 5–10 spare blades on hand
Q

What scroll saw blade should I use?

Reverse-tooth blades are the most popular choice because they cut clean on both top and bottom surfaces. Skip-tooth blades cut faster for rougher work, and spiral blades allow cutting in any direction without rotating the material.

  • Reverse-tooth: clean edges top and bottom, plywood standard
  • Skip-tooth: fast cuts, general purpose
  • Spiral: cuts in any direction, leaves rougher edge
  • Crown-tooth: cuts on push and pull stroke, smooth finish

Q

What material is best for scroll saw work?

Baltic birch plywood (1/4" or 3/8") is the most popular scroll saw material. It has consistent layers, cuts cleanly, and comes in flat sheets that lie flat on the table without warping.

  • Baltic birch plywood: most popular, consistent, affordable
  • Hardwood (maple, walnut): premium projects, natural beauty
  • Pine: cheapest, but soft grain can tear on tight curves
  • Corian: jewelry, inlays, requires slow speed and fine blade
Q

How do I estimate cut length for a scroll saw pattern?

Trace the total cutting path of your pattern with a piece of string, then measure the string. For simple silhouettes, the perimeter is a good estimate. Interior cuts add significantly to total cut length.

  • Simple silhouette: perimeter of the shape
  • Fretwork: perimeter + all interior cut paths
  • A typical 8" × 10" fretwork pattern has 40–80" of total cuts
  • Stack-cutting multiplies material but not blade wear per layer
