Instruction Example 5.2.: Scribing of the Runners

The foot and head runners for the partition wall shown in the detailed drawing are to be scribed.


Runner thickness: 80 mm
Runner height: 50 mm
Post width: 50 mm
Joint post width: 80 mm
Door size: 900/200 mm2

Pitch size for

wall (1) = 567.5 mm
wall (2) = 468 mm


Hand tools


Measuring and testing means

Folding rule, carpenter’s square

Auxiliary accessories

Pencil, template for post width, marking gauge, abrasive paper, one-ell trestles

Necessary previous knowledge

Reading of drawings, scribing, measuring, angling

Remarks to the working drawing

A head, B foot

Sequence of operations


1. Decide on the joining side of the runners.

2. Put runners for wall (2) on the trestles.

- Mind position of joining side.
(See Fig. 18 in Trainees’ Handbook of lessons.)
- Put runners closely together.
- Put runners about flush at left ends.
- Select distance of trestles so that runners cannot tilt up when scribing.

3. Scribe shortening at left ends of runners and mark with section mark.

- Go to the right only as far as necessary to produce a right-angle section.
- Place long leg of square at the longitudinal side of the runner at the front.
Scribe a thin line only.

4. Measure-in the pitch size.

- Mark only at the front edge of the runner at the front.
- Measure cumulatively.
- Check the total length.
(If markings do not fit into total length, find measuring error and make correction!)
- Remove or delete wrong markings.

5. Scribe pitch size and mark with jointing mark.

- Use the square.
- Make sure that the square is placed correctly.
- Mark with jointing mark at the correct side of scribed line! (work from jointing)

6. Scribe the post width.

- Use a template (piece of board having the exact width of the post).
- Scribe from jointing!

7. Measuring-in the posts for the door, scribe and mark with “T”.

- The sizes given in the detailed drawing are all finished sizes!
- The clear size for the door opening is to be scribed bigger at both sides because the door reveal will be provided with panelling (lining)!

8. Measure-in and scribe the additional post.

- Measure the thickness of the surface material for the wall covering plus post width from the foot runner of wall (2) to the left!

9. Scribe the mortise width.

- Use a marking gauge.
- Scribe from the joining side of the runners!

10. Scribe the corner tenons.

- Corner tenons are to be provided at
· wall posts,
· corner posts,
· door post,
· door fixing post.

11. Delete scribed post lines on the foot runner which are not needed.

- Posts in the area of the door opening.
- Delete with wavy line or abrase by means of abrasive paper.

12. Put runner for wall (2) on the trestles and scribe.

- Repeat steps 2., 3., 4., 5., 6., 9. and 10. accordingly!
If door openings are required in a partition wall to be built, the mortises are to be numbered on the head runner starting from the left.
The numbers are to be marked on the side opposite the jointing mark.
