Woodturning Blank Calculator
Free tools for woodturners: figure out how many bowl blanks a log will yield, get a rough-turning wall-thickness and drying-time estimate for green wood, and look up a sourced reference chart of common turning species. No signup, nothing uploaded — everything runs in your browser.
Log-to-bowl-blank calculator
Log diameter & length → how many blanks, and the max bowl size each one supports.
Rough-out wall & drying estimator
Bowl diameter & species → rough wall thickness and a drying-time range for twice-turning green wood.
Turning wood species reference
Sourced hardness, shrinkage, warp tendency, and dust-safety notes for 14 common turning species.
These are shop rules of thumb and published wood-property data (see each tool for sources), not a guarantee — always confirm a blank is actually dry by weight, not by calendar time.
