Workflow
Calculate Lumber Requirements
30 minutesConvert project dimensions to board feet, determine number of boards to purchase, and estimate material cost.
Account for Wood Movement
20 minutesCalculate expected shrinkage and expansion based on wood species, grain orientation, and local humidity changes.
Design Joinery
30-60 minutesSelect and calculate dimensions for joints (dovetails, mortise-and-tenon, dados) based on project structural requirements.
Build, Finish, and Evaluate
1-4 weekendsExecute the build following calculated dimensions, apply finish, and document material usage for future projects.

Board Foot FormulaFormula
Board feet = (Thickness in inches × Width in inches × Length in feet) ÷ 12. Or: (T × W × L in inches) ÷ 144.
Wood Movement by SpeciesTable
Tangential shrinkage percentages from green to oven-dry (representative values).
| Species | Tangential Shrinkage | Radial Shrinkage | Stability |
|---|---|---|---|
| White Oak | 10.5% | 6.6% | Moderate |
| Hard Maple | 9.9% | 5.8% | Moderate |
| Walnut | 7.5% | 5.5% | Good |
| Cedar | 5.0% | 3.0% | Excellent |
| Beech | 11.9% | 6.5% | Poor (high movement) |
Common Joint Selection GuideTable
Recommended joints by application and skill level.
| Joint | Strength | Skill Level | Best For |
|---|---|---|---|
| Dovetail | Excellent | Advanced | Drawers, boxes |
| Mortise & Tenon | Excellent | Intermediate | Frames, chairs |
| Pocket Screw | Good | Beginner | Face frames, carcases |
| Dado/Groove | Good | Beginner | Shelving, dividers |
Measure Twice, Cut Once
The most expensive lumber is the piece you cut too short. Verify every cut against your plan before touching the saw.
Invest in a Good Square and Measuring Tools
A $30 combination square and $15 marking knife improve accuracy more than a $500 upgrade to your table saw.
Mill Lumber Flat Before Cutting to Size
Joint one face, plane to thickness, joint one edge, rip to width, crosscut to length. This order prevents twist and bow.
Build a Mockup First for Complex Projects
Use cheap plywood or MDF to build a full-scale mockup of complex joinery before cutting expensive hardwood.
Safety Notes
- Always use push sticks and featherboards on table saws — kickback causes severe injuries. Never stand directly behind the blade.
- Wear dust collection and a respirator when sanding — wood dust is a known carcinogen (IARC Group 1 for hardwood dust).
