Turngrain: Bowl Studio
Blanks, Drying & Cut Plans
$1.99 · Designed for iPad. Not verified for macOS.
Catalog blanks, calculate rough-wall targets, record weight loss, watch drying stability, plan remounts, and export a bowl card.
Turngrain is a private woodturning studio for following a blank from green log to finished bowl.
Catalog species, source, grain orientation, dimensions, defects, seal date, rough-turn dimensions, weight, moisture observations, drying method, and storage address. The Drying Bench plots entered weight loss, calculates change between checks, estimates rough-wall targets from diameter, and flags when recent measurements are becoming stable without claiming the blank is ready.
KEY FEATURES
