Oblique locked crossings
When weavers cross at a non-perpendicular angle, they can still be locked using four notches in each weaver.
And they engage in the same manner as for a perpendicular crossing.
The centers of the engagement windows no longer form a square (as they do at a perpendicular crossing) but a rhombus. When the notches terminate in a circular radius, the circle centers do not form a rhombus, rather a parallelogram.
The acute angle of parallelogram (and thus the acute angle of the weavers crossing) ends up being a little wider than the acute angle of the rhombus. In the diagram above, 33 degrees vs. 30 degrees in terms of half-angles.
The bottom line: we can program oblique locked crossings with same shape notches used for perpendicular locked crossings, we just need to make some adjustments in their positioning along the length of the weaver.
wonderful to see this - Beautiful and inspirino as ever! Thank you so much, Alison.
