The third revision of the stand-frame came off the CNC at the workshop this week. Twelve parts. Four fixings per node. The whole frame can be carried by two people, stood up by one, and braced into a temporary structure in under fifteen minutes.
The tolerance is ±1 mm — tight enough that the fixings drop in by hand, loose enough that thermal movement doesn’t bind the joints in a heatwave. This is the headline number, but it isn’t the point.
The point is that v3 is the first version of the stand-frame where we did not have to think about the joinery while drawing the architecture. The system absorbed it. That’s what we mean by productised construction: the joinery is a parameter, not a problem.
