This is an outline generated by Copilot; as an outline it seems quite thorough; obviously there are lots of bits to add but basically i was interested in the History of Software Engineering from the first SDE (Ada Lovelace) to today (which seems almost entirely AI-centric).

* balancing * hook alignment * how to choose weight * Golding RingSpindles Drop spindles come in (at least) 2 basic types: * supported (pointed end above whorl, typically held in a bowl and spun as a bottom-whorl spindle) * suspended (hooked end above whorl) * top-whorl (whorl near hook) * bottom-whorl (whorl at other end of shaft from hook)

balancing

copy-paste from CoPilot discussion to be edited as time allows: Balancing a wooden whorl with normal shop tools is absolutely doable, and once you understand static balance, the whole process becomes predictable instead of mystical. What Golding achieves with machining, you can approximate with careful measurement, controlled removal, and a simple balancing jig.

A yarn bowl, in its simplest form, is a flat-bottom enclosed-form bowl for holding one or more balls of yarn while they're being used for knitting and other knitting-like activities. Its purpose is to keep the yarn under control as it's being used. In most cases this also calls for a hole and/or groove in the side of the bowl to allow the yarn to be pulled thru. Ideally the bowl is also somewhat heavy so that pulling on the yarn doesn't cause the bowl to slide towards the knitter. The form i…

started woodturning in May 2017; learned much, some of which is probably right and true; much of which is subjective opinion that works for me. your mileage may vary. :) * Stu's Principles of the Perfect Cut * my own learnings... * Vicmarc Jaw Ranges * Lidded Boxes * Drop-Spindles * Yarn Bowls

Polygons Regular Polygons * polygons inscribed within a circle of radius R with equal side length s * each side also spans an arc of angle Θ * we can easily calculate the side s via General Pythagorean * c2 = a2 + b2 - 2ab * cos(Θ) where c is the side opposite Θ
