Forty-eight sketch pages open the notebook, and they are unruled on purpose. A gear train drawn at an angle, then drawn again from above, does not sit neatly inside a printed line, and a lined page fights the second drawing instead of holding it.
Eight project pages follow, one to a design, for the concept, the dimensions, the materials, the mechanism and the revision history. A revision written down next to the sketch it replaced is a revision somebody can still explain a year later.
Thirty-one pages of plain notes close the book, for the calculation that does not belong on a project page. It carries no printed drawing standard or tolerance convention. Those come from the standard you design to, ISO or ASME or your employer's own, and a blank page cannot choose one for you.
What is inside
- Sketch
- 48pp
- Unruled, so a mechanism drawn from two angles is not fighting a printed line.
- Project
- 8pp
- One page to a design, for the concept, the dimensions, the materials, the mechanism and the revision.
- Notes
- 31pp
- Plain paper, for the calculation that does not belong on a project page.
- Reference
- 13pp
- The book closes with reference pages: length and angle conversions from definitions, emergency numbers checked against two sources.
In every book
The same six pages open every book: your details, who to call, the signs to point at when you have no shared language, and the map. They sit at the front because the moment you need them is not the moment to be flicking through.
- This book belongs to
- One page for your name and number, so a book that goes missing can come back.
- My details
- Blood group, allergies, who to call. Written once, carried everywhere.
- Emergency numbers
- Forty countries, taken from Wikidata property P2852 (CC0), agreed across two sources, every row carrying its QID. Numbers change and a book does not — verify locally on arrival.
- Point at this
- A pictogram grid captioned in English above and Indonesian below, for when there is no shared language.
- World map
- Natural Earth 110m, public domain, equirectangular, with UTC hour meridians computed from the projection rather than from a timezone database. For orientation and for pointing at, not a navigation chart.
- Conversion tables
- Computed from definitions — 25.4 mm to the inch — and not copied from anywhere, so every row can be checked by anyone holding the book.
- Pen test leaf
- The last page, printed for it on purpose. Every notebook is used this way; printing it deliberately is cheaper than losing the last leaf to it by accident.

Questions
What does a project page cover?
The concept, the dimensions, the materials, the mechanism and the revision history.
What ruling are the sketch pages?
Unruled. Sketch pages carry no lines at all.
How big is it?
A5, 100 pages, spine 5.72 mm, unruled throughout.
Is it dated?
No. Open it with your first concept sketch.
Does it set a drawing standard or tolerance convention?
No. Dimensioning and tolerancing conventions come from the standard you design to, ISO or ASME or your employer's own, and a blank page cannot choose one for you.
The primary shadow is always the basis of the derived shadow.
