Planning estimate: The model includes two full top layers, eight leg laminations, four long rails, four end rails, and one inset shelf. It does not certify racking resistance, load capacity, vise support, caster loads, joinery, or safe machine operations.
Visible arithmetic
leg length = finished height − (2 × top thickness)
The model includes two full top layers, eight leg laminations, four long rails, four end rails, and one inset shelf. It does not certify racking resistance, load capacity, vise support, caster loads, joinery, or safe machine operations.
Use the generated rectangles as a transparent starting point. The layout does not replace a construction drawing, hardware specification, load calculation, or safe cutting procedure.
Before material purchase
Checks the calculator cannot make from dimensions alone
Design diagonal, back-panel, or rigid frame bracing against racking.
Reinforce the top locally for vises, machines, and dog holes.
Confirm the assembled bench load path and floor contact.
Verify that every long rip can be handled safely with the available tools.
