or maybe a less musical one :D
I think it's funny that a majority of the reason the insert/adapter is shaped in this way is to save on material: a simple disc uses something like 20% more material (usually plastic, I think?) to produce than this cooler looking shape which also makes a good martial arts clan insignia...and also a throwing star. :p
if Bob will forgive me for saying, one thing that is not present in his drawing is the grooving - the tab ends of the insert had inset grooves, and it is the shape it is so that you could compress the tabs slightly, necessary in order to fit the grooves over the outer circumference of the hole and grip tight
as far as I know the shape has nothing to do with saving material.... just to give spring and grip
I remember it the other way round ... I seem to remember that the hole in the 45 was grooved and the tab ends had a slight tongue, but I could be wrong.
my memory isn't perfect these days, but the ones I remember are the ones Bob drew so well - if you look at the last set of images in the article linked here:
https://arcmusic.wordpress.com/2008/...he-45-adaptor/
the far left image shows the overlap, insert/adaptor over record.. thats how I remember it and struggling to learn how to fit it when young :D
still doesn't mean I'm right 'twas a long time ago ...
