Every ring sized, every angle set.

Segmented turning is arithmetic first and lathe second. Ring & Stave does the arithmetic, draws it, and hands you the cut list.

WHAT IT DOES

• Single ring: miter angle, outer and inner segment lengths, board length and width, spares, drawn to scale with the finished ring dashed inside it
• Checks your turning margin against the flat between segment corners so the outside actually cleans up
• Vessel designer: drag a profile and the app stacks rings against it, each sized to cover the outside curve and the inside wall with your margin
• Solid base disc or open ring at the bottom, any wall thickness, any board thickness
• Cut list: ring by ring with OD, ID, width, miter, lengths and board, plus totals and board feet. Prints clean
• Staves: blade tilt and miter gauge angle for the compound cut, stave widths at top and bottom, length, lean angle, margin check
• Inches with fractions to 64ths, or millimetres
• Backup and restore your projects
