Instruction Example 5.5.: Scribing of the Door Framework

The door framework for the partition wall (1) is to be scribed.

Known:

- Door height: 2000 mm
- Door width: 900 mm
- Door posts are already scribed.
- Door lintel transom size

d = 80 mm, h = 50 mm, l = 1800 mm

Figure

Hand tools

Hammer

Measuring and testing means

Folding rule, carpenter’s square

Auxiliary accessories

Pencil, marking gauge, abrasive paper, one-ell trestles

Necessary previous knowledge

Measuring, angling, scribing, reading of drawings

Sequence of operations

Comments

1. Put posts 3 and 6, as well as door posts “4” and “5” on the trestles.

- Place the scribed lines flush.
- Jointing marks to be at the left and on top.
- Sequence is important!
Start at front:
Post 3
door post “4”
door post “5”
post 6.

2. Measure-in position of door lintel transom, scribe and mark.

- Measure from surface of floor.
Scribing size:
clear door height minus foot runner plus 20 mm allowance for jamb lining
(2000 mm - 50 mm + 20 mm = 1970 mm)
- Measure-in the size on the post at the front, place the square and scribe.

3. Take out the door posts and move posts 3 and 6 closely together.

- Leave the door posts on the trestles.
- Do not change the jointing marks.
- Put the scribed lines of posts 3 and 6 flush.
- Post 3 to remain at the front!

4. Measure-in and scribe the lintel transom height.

- Use the square.

5. Scribe the mortises.

- Scribe from the joining side.
- Scribe only on the front side of post 3 and onto the rear side of post 6.
- Use the marking gauge; do not cant it.

6. Scribe and mark the tenon length on the door posts.

- Measure and scribe from the scribed door lintel transom line towards the head runner.
- Mark the scribed line with section mark.

7. Scribe the tenon parapets.

- Scribe the front and rear parapets from the joining side.
- Delete or abrase the scribed mortise lines for the stiffening transoms on the side opposite the corner tenon.

8. Put the door lintel transom on the trestles and mark with jointing mark.

- Scribe the joining side at door lintel transom height

9. Scribe the shortening and mark with section mark.

- Go only as far as necessary to produce a right-angle section.

10. Measure-in and scribe the tenon length and door lintel transom length.

- Measure-in and scribe the tenon length at the left end.
- Measure-in and scribe the door lintel transom lenghts
(Take the length from the head runner! Clear size between the posts 3 and 6).
- Measure-in the tenon length at the right end, scribe and mark with section mark.

11. Scribe the tenon parapets.

- Scribe the front and rear parapets from the joining side.

12. Scribe the mortises for the tail posts.

- Scribe on the top face of the door lintel transom!!!
- Take the sizes from the head runner.
(Place batten to contact post 3 and transfer scribed lines onto batten).
- Scribe tenon parapet and mortise width from the joining side.
- Use the marking gauge and do not cant it.

13. Scribe the mortises for the door posts.

- Scribe on the bottom face of the door lintel transom!
- Take the sizes from the foot runner.
(Place batten to contact post 3 and transfer scribed lines onto batten).
- Scribe the tenon parapet and mortise width from the joining side.
- Use the marking gauge.

14. Scribe the tail posts.

- Use the sections of the door posts.
- Take the size from post 3 and transfer it to the tail post.
- For the joint tail post, a cover strap of 20 mm thickness is to be nailed on the erected partition wall at the side of the joint tail post opposite the jointing mark.
