1. Wood Species Characteristics

Each wood species brings unique properties that determine its suitability for different applications. Ria Harman's selection philosophy at Prairie Craft emphasizes matching wood characteristics to project requirements, considering factors like workability, stability, appearance, and durability.

Hardwood Categories

Temperate Hardwoods
  • Oak: Traditional strength, prominent ray patterns
  • Maple: Fine grain, excellent for detailed work
  • Cherry: Beautiful aging, premium furniture wood
  • Walnut: Rich chocolate tones, easy workability
  • Ash: Strong, flexible, ideal for bent parts
Regional Specialties
  • Eastern Red Cedar: Aromatic, insect-resistant
  • Hickory: Exceptional strength, shock resistance
  • Cottonwood: Light weight, carving applications
  • Elm: Interlocked grain, unique figure
  • Osage Orange: Extreme density, specialty uses

Physical Properties Matrix

Understanding density, hardness, and stability helps predict how wood will behave during construction and use. Dense woods like maple and oak provide durability but require sharp tools and careful technique. Softer woods like pine and poplar machine easily but may not hold detail or resist dents.

Prairie Craft Selection Rule: Always consider the end use when selecting species. Dining table tops require different properties than cabinet backs. Match the wood's strengths to the application's demands.

The USDA Forest Products Laboratory provides comprehensive technical data on North American wood species, including strength properties and identification features.

2. Grain Patterns & Figure

Grain pattern significantly impacts both appearance and structural properties. Ria Harman teaches that understanding grain orientation is essential for predicting wood movement, optimizing strength, and achieving desired visual effects in finished pieces.

Sawing Methods & Grain Patterns

Plain Sawn

Most economical cut

Wide boards, cathedral grain patterns, greatest movement across width. Good for painted surfaces.

Quarter Sawn

Maximum stability

Ray patterns visible, minimal movement, higher cost. Preferred for table tops and panels.

Rift Sawn

Straight grain lines

Uniform appearance, good stability, premium price. Ideal for visible frame members.

Special Figure Types

Figured wood commands premium prices due to its exceptional beauty and rarity. Bird's eye maple, tiger maple, and curly cherry result from growth irregularities that create stunning visual effects. These woods require careful handling and finishing to highlight their unique characteristics.

Grain Matching Techniques

Book matching creates mirror images by opening consecutive boards like book pages. Slip matching maintains grain direction for continuous patterns. End matching extends patterns across panel lengths. These techniques require careful lumber selection and skilled execution but create stunning visual effects.

Professional Tip: When selecting lumber for grain matching, choose boards from the same tree whenever possible. Wood from the same log will have similar color and grain characteristics, making matching easier and more successful.

3. Lumber Grading & Quality Assessment

Understanding lumber grades helps you purchase appropriate quality for your project while managing costs effectively. The National Hardwood Lumber Association (NHLA) grading system provides standardized quality measurements that Ria Harman and our Prairie Craft team use for all lumber purchases.

NHLA Grading Standards

Premium Grades
  • FAS (Firsts and Seconds): 83.3% clear lumber minimum
  • FAS 1-Face: One face FAS grade, back side #1 Common
  • Select: 83.3% clear minimum, narrower than FAS
Common Grades
  • #1 Common: 66.7% clear lumber minimum
  • #2 Common: 50% clear lumber minimum
  • #3A Common: 33.3% clear lumber minimum

Defect Evaluation

Not all defects disqualify lumber for fine furniture. Sound knots can add character to rustic pieces. Pin knots in cherry and maple are often considered desirable. Sapwood in some species provides color contrast. Understanding which defects to accept and which to avoid saves money while maintaining quality.

Grade Selection by Application

Visible surfaces require higher grades (FAS or Select) for clean appearance. Hidden structural components can use lower grades (#1 or #2 Common) effectively. Secondary surfaces may use #1 Common grade. Matching grade to application optimizes both quality and cost.

The National Hardwood Lumber Association provides complete grading rules and inspection training for professional lumber evaluation.

4. Moisture Content & Drying

Proper moisture content is crucial for stable furniture construction. Wood continues to exchange moisture with its environment after construction, causing expansion and contraction. Ria Harman's experience shows that understanding and controlling moisture content prevents most construction problems.

Target Moisture Levels

Interior Furniture

6-8% moisture content

Matches typical interior humidity levels. Provides stability while allowing for seasonal movement.

Exterior Applications

12-15% moisture content

Higher moisture matches outdoor conditions. Requires weather-resistant species and finishes.

Acclimation Process

Allow lumber to acclimate to workshop conditions before use. Stack boards with stickers for air circulation, away from heat sources and direct sunlight. Check moisture content with electronic meters before milling. Acclimation typically requires 1-2 weeks depending on initial moisture content and environmental conditions.

Common Mistake: Using lumber immediately after delivery often results in warping, checking, or joint failure as the wood adjusts to shop conditions. Always allow proper acclimation time for stable results.

5. Defect Evaluation & Management

Skilled woodworkers know how to work around defects or incorporate them as design elements. Ria Harman teaches that understanding different defect types and their implications helps maximize lumber yield while maintaining quality standards.

Acceptable vs. Problematic Defects

Workable Defects
  • • Sound knots (tight, no movement)
  • • Color variation in sapwood
  • • Minor surface checks
  • • Mineral streaks in some species
  • • Slight bow or crook (under 1/4")
Problematic Defects
  • • Loose or missing knots
  • • Deep splits or shakes
  • • Severe twist or wind
  • • Active insect damage
  • • Staining or fungal infection

Defect Remediation Techniques

Small defects can often be repaired with wood plugs, dutchman patches, or epoxy fills. Surface checks may close during milling. Bow and crook can be removed through careful resawing. The key is assessing whether remediation costs justify saving the lumber versus purchasing higher-grade material.

6. Milling & Preparation Techniques

Proper milling sequence ensures dimensional stability and optimal results. The Prairie Craft methodology, developed by Ria Harman, follows time-tested procedures that professional furniture makers have used for generations.

Standard Milling Sequence

  1. 1

    Rough Cut to Length

    Add 2-4 inches to final length for defect removal and jointing.

  2. 2

    Joint One Face Flat

    Remove any bow, cup, or twist. This becomes your reference surface.

  3. 3

    Plane to Thickness

    Remove material from unjointed face, referencing off jointed face.

  4. 4

    Joint One Edge Straight

    Reference off flat face for perfectly square edge.

  5. 5

    Cut to Final Width

    Rip to width on table saw, referencing straight edge.

  6. 6

    Cut to Final Length

    Crosscut to final dimensions with square, clean cuts.

Prairie Craft Method: Allow wood to rest between major milling operations, especially when removing significant material. Stress relief can cause movement that requires adjustment before final dimensioning.

7. Storage & Handling Best Practices

Proper storage protects your lumber investment and ensures quality remains high until use. Ria Harman's storage methods at Prairie Craft maintain lumber condition regardless of seasonal changes or workshop conditions.

Lumber Rack Design

Support lumber every 16-24 inches to prevent sagging. Use stickers (thin strips) between layers for air circulation. Ensure stickers align vertically to prevent bowing. Weight the top of stacks to keep boards flat. Cover outdoor racks to protect from direct rain while allowing air circulation.

Environmental Control

Maintain stable temperature and humidity when possible. Avoid storing lumber near heating equipment or in areas with extreme temperature swings. Good ventilation prevents condensation and fungal growth. Monitor storage areas with hygrometers to track conditions.

Inventory Management

Rotate stock using first-in, first-out principles. Label lumber with species, grade, moisture content, and purchase date. Keep similar species together for easy selection. Maintain inventory records for project planning and reordering.

8. Sustainable Sourcing & Environmental Responsibility

Sustainable forestry ensures future generations will have access to quality lumber. At Prairie Craft, Ria Harman prioritizes suppliers who practice responsible forest management and support local forest communities.

Certification Programs

FSC Certification

Forest Stewardship Council

Ensures responsible forest management practices that protect biodiversity and support local communities.

SFI Certification

Sustainable Forestry Initiative
