On occasion I will do something practical:
It’s not that we needed a rack for those cans, but it did get a laugh from Mary and that’s what counts.
In order from left to right, the three successive racks represent:
- A good laugh
- Finding that a burn correction parameter of 0.04 produces a much better fit than 0.05.
- Discovering that I must orient finger joints along the same axis to minimize small axis scale errors errors
The axis scale error, however, took me by surprise.The X axis travels on the order of 0.2 mm more along 250 mm, about 0.08%, than the Y axis, even after my tedious calibration. I must do that calibration again, because, as Miss Clavel observed in a different context, Something Is Not Right.
And, yes, that tiny difference is enough to misalign the last few fingers with their holes, to the extent of requiring somewhat more than Gentle Persuasion with a plastic mallet.
