After 90° rotation = board thickness. ¼″ is automatically added for flattening allowance.
② Stock & Milling
After rotation, this sets the board length
Sets board width and visible end grain pattern
③ Crosscut & Kerf
Auto-calculated: your target thickness + ¼″ flattening allowance
Standard 1/8″ (0.125). Thin-kerf 3/32″ (0.094).
④ Waste Allowances
Per glue-up, for trimming & squaring. Typical ¼″–½″.
Extra length per strip for snipe and end squaring.
Suggested: 20%. Added to your total board footage to cover purchasing overage, defects, and off-cuts. Board footage is calculated on rough/pre-milled stock size (¼″ added to strip width and thickness), so this covers material loss beyond that.
Stage 1 Results — Slab Glue-Up
Stage 2 Results — Crosscut & Final Glue-Up
Cut List Summary
Board footage is calculated using rough/pre-milled stock dimensions: strip width + ¼″ and stock thickness + ¼″, multiplied by strip length and strip count. This reflects what you actually need to purchase, not the net size after milling. Adjust the waste factor above for your shop yield.
The Two-Stage Process
① Rip Strips
Rip your lumber stock into strips. Strip Width sets the visible end grain pattern size. Stock Thickness will become the board length after rotation.
② Glue Slab
Glue strips edge-to-edge into a slab with edge grain facing up. Slab width = number of strips × strip width.
③ Crosscut Slab
Once dry and flat, crosscut the slab into equal segments. The Crosscut Segment Width becomes the board’s final thickness after rotation.
④ Rotate 90°
Rotate each segment 90° so the end grain faces up. Re-glue the segments side by side into the final panel.
⑤ Flatten & Trim
Flatten both faces (drum sander or planer), then trim to final length and width. ¼″ of thickness is already included in the segment width for the final flatten.
Key Relationships
Board Length
Number of Segments × Stock Thickness. More segments or thicker stock = longer board.
Board Width
Number of Strips × Strip Width. More strips or wider strips = wider board.
Board Thickness
Crosscut Segment Width minus material removed in flattening (¼″ auto-added).
Board Feet (how it’s calculated)
Uses rough/pre-milled dimensions: (Stock Thickness + ¼″) × (Strip Width + ¼″) × Strip Length ÷ 144, × number of strips. The ¼″ added to each dimension accounts for the extra material on rough lumber before jointing and planing to net size.
