Worm wheel

Use worm wheel for this pattern

180:1 · 8 divisions per turn
1 division = 0.25 spindle degrees

Type each move, separated by commas. Each number moves the worm dial that many divisions before the next cut.

For eight equal moves, type 3, 3, 3, 3, 3, 3, 3, 3. Copy and paste into another line to repeat them. Long lines scroll sideways. Cutting rotation stays CW.

Gold dots = notches used by this pattern. Gray ticks = available notches.

1 cut · no moves yet

Custom moves / change direction

Lift the pawl, move this many notches, lock it, then cut. Each number is a move from the previous position.

1, 1, 2 moves one notch, one more, then two more. Repeat a move by typing the number again. 0 keeps the alignment. Cutting rotation stays CW; the cutter steps inward between cuts.
