Tailstock: Segmented Bowls

Design segmented bowls ring by ring and stop guessing at the miter saw. Tailstock works out every ring's segment lengths and miter angle, draws the bowl's profile, and keeps the other numbers you need at the lathe in your pocket.

Built for woodturners, from your first segmented ring to a showpiece bowl. iPhone and iPad, imperial or metric, fractions or decimals.
