Rings, segments and cuts, from the size you want.
A segmented turning planner for anyone. Free to use; sign in to keep your designs.
I know the finished size
Bottom, rim, height and wall. Lathewise works back to the rings, the segments and the miters.
Give me a starting point
Pick a bowl, cup, dish or vase and a size. Adjust from there.
Inches or millimetres, your choice. Nothing to install.
What are you making?
The outside sizes of the finished piece. Lathewise adds the turning allowance.
Pick a shape
A sensible piece to begin with. Every number can change later.
Your plan
Drag to turn it, pinch to zoom, double-tap to reset.

Rings
| Ring | Outside Ø | Segment | Rip width |
|---|
Sizes include the turning allowance. Cut to these, glue the ring, true it, then turn.
Lumber
Shape your piece
Drag the dots. The rim dot climbs or drops a whole ring at a time. Two quick taps on the curve add a dot; two on a dot take it away.
Rings
Walls and woods
Paint the rings
Every ring unrolled, one cell a segment. Pick a wood, then tap a cell or drag along a ring. Tap a ring number to work on that ring.

What to cut
Every segment of a ring is the same. Set the saw once per ring.
| Ring | Wood | Pieces | Long side | Width | Miter |
|---|
Long side is the outside of each segment. The miter is the saw's angle at each end; the two ends together make the segment's wedge.
The name
Lathewise is two old words joined.
-wise means in the manner or direction of. A board is cut lengthwise or crosswise; a blank is mounted spindlewise. So lathewise means shaped the way a lathe shapes: a piece turning about one axis while a still tool brings it round and true.
-wise also means knowing, as in streetwise. Lathewise is knowing the lathe before the first cut: how many rings, how many segments, what angle to cut them at, how wide to rip the boards and how much wood to buy.
Lathewise takes the measurements you have, the finished size you want or a starting point you like, and works the rest out: the rings, the segments, the miters, the cut list and the lumber. It is one word, written Lathewise, and it is free to use.
