KNITTING PATTERNS.
A knitting pattern is simply a list of the settings used to make a design

Creating a 'Knitting Pattern'

To create a knitting pattern, all that is needed is to analyse a design into its component settings and write them down row by row.

For instance, Twelve cut Basketweave pattern can be written simply as: -

Square Cutter. (Define cutter width)
Cuts 12
Row 1. Offset 0. Cut until cuts meet.
Reposition cutter sideways (Cutter width)
Row 2. Offset 6.
Reposition cutter sideways (Cutter width)
Repeat for (x) rows, finishing on Offset 0.

Eighteen cut basketweave pattern can be written as: -

Square Cutter (Define cutter width)
Cuts 18
Row 1. Offset 0. Cut until cuts meet.
Reposition cutter sideways (Cutter width)
Row 2. Offset 4.
Reposition cutter sideways (Cutter width)
Repeat for (x) rows, finishing on Offset 0.

When using a Knitting pattern, the first row of cuts is made, and subsequent rows are cut in the following manner.

  1. Back the cutter away from the work using the advance wheel, and stop the lathe.
  2. Position the cutter to the next position using the cutterbody guide, and lock it in position with the screw.
  3. Change the offset setting on the control box.
  4. Start the lathe, and when the cutter starts to move, advance the cutter toward the work using the cutter advance wheel.
  5. By observing the 'blur' made by the cuts on the workpiece, make a judgement as to how deep the cuts are. When they are deep enough, stop the lathe to check.
  6. Stop and start the lathe as often as may be necessary to ensure that the cuts are to the correct depth.
  7. When the cuts are to the correct depth, repeat steps 1-6.

More complex patterns can be written in the same manner as the simple ones seen above.

The leaf pattern seen here can be written as:

@ 2.5in diam. 8 Cut Pattern. 2.5mm. round cutter.

      Row 1. Offset 0. Set depth to give ellipse length x3, width x1.
      Reposition cutter sideways 0.75mm. between rows.
      Row 2. Offset 3
      Row 3. Offset 5
      Row 4. Offset 6
      Row 5. Offset 5
      Row 6. Offset 3
      Row 7. Offset 0
      Change cutter to 90degree V point, reposition in line with row 4.
      Row 8. Offset 15
