Sheet A-200

Structural timber

Material: Frame timber, 45 × 45 × 4 200 mm. Quantity: 8 lengths.

Caution · verify the stock first

Make sure that your stock matches the material. These sheets are exact only for this material size. One 2.8 mm kerf is used for every piece.

Cut every piece at one stop setting before you change the stop. A batch that reaches the end of a stock length continues on the next length.

Brace rule

LSD1 and RSD1 are cut at 34.9° at both ends. BWD1 and DBD1 are cut at 41.2° at both ends.

These are long-point lengths. Keep each pair of end cuts parallel. Turn the workpiece, not the saw setting, to make the parallelogram.

Sheet A-300

Råspont

Material: Råspont, 120 × 23 × 4 500 mm. Quantity: 12 lengths.

Caution · verify the stock first

Make sure that your stock matches the material. These sheets are exact only for this material size. One 2.8 mm kerf is used for every piece.

The first 8 stock lengths release all twenty-three 1 175 blanks. Fourteen side boards come first, then nine door boards, at one stop setting.

Operation A · release every 1 175 blank

  1. Set the stop once. Cut all twenty-three blanks from P01 onward. Mark each code immediately. When a stock length ends, continue at the same setting on the next one.
  2. Label the P01 to P03 remainders. Keep them for the final 397 pass.
  3. Move every marked blank to its unit stack. Do not join or trim loose cladding.

Operation B · cut the remaining pieces

Change the stop only once per row. Cut every piece in that row, then move to the next stop. The final 397 row uses the labeled P01 / P02 / P03 remainders.

Do not trim loose cladding

Gaps between boards change the joined width. Fix each board to its unit frame before you mark any final edge.

Use the frame edge to set the circular-saw guide. Cut only after the boards are fixed. Sheet A-400 shows each estimated overhang and cut line.

Unit drawings and assembly

Each drawing is an orthographic projection off the model. Solid members are the frame. Tinted fields are cladding. Hatching shows the nominal material left for an on-frame cut.

Use the Frame and Cladding controls to change drawing emphasis. The printed drawing keeps every cut line, trim label, and notch note visible.
