The Build Log

How big is every single part?

Station 1 of 5 on the road every made thing goes down. Decide what it is, then dimension every part of it.

How long
As long as you like. Nothing here is timed.

Try this at the table.

One for each object. A greyed-out one is not us being lazy. It is a thing that cannot honestly be done until somebody clears the gate written on it.

1The Jumbo

The drawings are done and you still cannot have them.

Seven sheets exist. They are drawn and they are still being torn apart by reviewers. They stay off this page until they are signed, because an unsigned drawing is one someone can still change, and a shop that builds from one is building the wrong airplane. That signature is the only thing between here and the next station.

You needPatience

IdeaRevision control. A drawing nobody signed is a drawing that can still change under you.

2Max — Mascot Figure Lamp

Print the drawing and find eight hinges.

This is sheet one of Max, the real one, the same page a shop gets. Every number on it is millimetres. Somewhere on it are eight places where he bends. Find all eight, then look at your own arm and work out why a shoulder needs one and an elbow needs a different one.

IdeaJoints. Every place a thing bends is a decision somebody made on purpose.

3Larry

Flatten something round and see where it lies.

Larry is sewn out of eleven flat pieces, and none of them started flat. Take an orange, peel it in one go, and press the peel down onto the table. It will not lie flat -- it tears, or it wrinkles, and where it does is exactly where a pattern has to cheat. Then look at his neck piece, which cheats by eight percent, and at his foot pad, which does not cheat at all.

IdeaYou cannot press a ball flat. Every map of the world and every stuffed animal is a different answer to the same problem.

That is the end of this one

The word for what you just did is design engineering.

Design engineering is what a grown-up calls this station on a resume. It is one of five, it always happens in this order, and skipping it does not save you the work. It only moves the work to a later station where it costs more.
