Dated field notes → Journal
What broke this week, bench conditions, running headers. Shop-floor notes as they happened — explicitly not the how-to archive.
Guide library · 581 published entries · en-US
Every procedure here was built at the bench before it was written down.
581 guides, tutorials and field notes on 3D printing, electronics and workshop fixtures — each logged on a bench card, rebuilt by a second pair of hands from the words alone, and left at its original /%postname%/ address. No unboxing, no spec-sheet rankings: the tolerances, the bench conditions, the part that failed, and the fix that held.
Ordering: grouped by category, newest bench date first. Evergreen procedures are never rotated out.
Shelf structure
Walk the stacks by category
Five working shelves. These are plain jump links — nothing filters, nothing hides, and every row below stays reachable with a keyboard or a thumb.
- 01
3D printing
First-layer adhesion, tolerance test coupons, bowed beds.
- 02
Electronics
Joint quality under a loupe, ground planes, current paths.
- 03
Workshop fixtures
Jigs, stops and clamps cut for one specific awkward part.
- 04
Materials
Batch behaviour, storage, and what a spool does after a year.
- 05
Reference
Tables read on the page: tolerances, fasteners, wire gauge, cost per part.

Grouped by category · newest bench date first within each group · nothing rotated out
3D printing
-
Setting first-layer squish without a feeler gauge
Bed mesh reads fine but the skirt still lifts at the front-left corner.
-
Measuring true tolerance with a 12-coupon rack
Single test prints hide the spread — four printers disagree by 0.09 mm.
Electronics
-
Reading a cold joint through a loupe
Joint looks solid at 3× and fails a pull test at 8×.
Workshop fixtures
-
A drill stop that survives a slipped chuck
Split-collar stops creep on 8 mm shanks after a few hundred holes.
Reading the row
What the metadata on each entry attests to — and what it doesn't
- Bench date
- When the build was logged on the Long Bench card. It is the date of the work, not a claim that the guide was re-verified later.
- Second hands ✓
- A second person reproduced the build from the written steps alone, without asking the author anything. Fail this gate and the draft does not publish.
- Errata
- Dated appendices under the original article. The original text is left standing so you can see what changed and when.
- Permalink
- Held at its original /%postname%/ address on all 581 articles. The redesign changed how the site reads, not where a piece lives.
Guides describe one bench's experience under stated conditions. They are not a certified procedure, and no result is guaranteed across every printer, board or material batch.
Four gates
Nothing reaches this library that a second person could not rebuild from the words alone
- 01
Bench card, filled by hand
Tool, material batch, ambient temperature and humidity, and the step that nearly ended the build — written on paper at the bench, not reconstructed afterwards.
- 02
Draft written from the card
Steps follow the card, including the failure. Any step that needed verbal clarification is rewritten before the draft moves on.
- 03
Second-hands rebuild
A different pair of hands reproduces the build from the text only. If a question has to be asked, the guide goes back to the bench.
- 04
Dated errata, if the fix moves
A year later the fix either held or it didn't. If it didn't, a dated appendix is appended under the original — never a silent edit.
Where a question belongs
Three duties, three rooms
Tables and worksheets → Resources
Printer tolerance charts, metric and imperial fastener equivalents, wire gauge and current references, cost-per-part worksheet. Meant to be read on the page.
Corrections → Contact
A reading-and-corrections channel, plus the bench and the publication rules on About. The display layout there is a preview; nothing is transmitted or stored.
