◈ CRAFTSMAN TIMBER & JOINERY LAB
Precision math for fine woodworkers.
Eliminate lumberyard guesswork and cracked tabletops. Calculate exact board feet volume, optimize 1D saw blade kerf cutlists, lookup screw pilot holes, and model seasonal wood movement.
INTERACTIVE TOOLS
Craftsman Calculation Bench
Four dedicated single-purpose tools calibrated for furniture makers, remodelers, and carpenters.
01 / WORKSHOP BENCH
Board Feet & Rough Lumber Estimator
Convert rough or surfaced lumber dimensions and board quantities into exact board feet volume with customizable pricing and waste allowance.
02 / WORKSHOP BENCH
1D Cutlist Optimizer & Bin Packing
Determine how many standard 8ft, 10ft, or 12ft boards you need for your furniture project, with full saw blade kerf accounting and visual board diagrams.
03 / WORKSHOP BENCH
Wood Screw Pilot & Clearance Hole Chart
Lookup precise straight drill bit diameters in fractional and decimal inches for wood screw gauges #4 through #14 in both hardwoods and softwoods.
04 / WORKSHOP BENCH
Tabletop Wood Movement & Shrinkage
Calculate cross-grain seasonal expansion and shrinkage based on species-specific tangential/radial coefficients and equilibrium moisture content (EMC).
BENCH NOTEBOOK
Wood Science & Joinery Notes
Lumber Procurement
Understanding Board Feet: The Hardwood Yard Buying Guide
Why hardwood is sold by volume rather than linear feet, how 4/4 and 8/4 quarter sizes work, and how much waste to buy.
Workshop Workflow
1D Cutlist Optimization: Balancing Waste with Continuous Grain Matching
Why mathematical bin-packing must be balanced with grain continuity across drawers, table aprons, and door frames.
Joinery & Fasteners
The Physics of Wood Screws: Pilot Holes, Clearance Holes & Countersinks
Why driving a screw directly into hardwood splits boards, and the critical difference between pilot holes and clearance holes.
Furniture Engineering
Seasonal Wood Movement: Why Tabletops Crack and How to Fasten Them
Wood expands and contracts like an accordion across the seasons. Here is how to engineer tabletop joinery that never splits.
