      He used Chapstick as a heavy grease to hold ball bearings in place to re-insert the carriage and ball bearings into a Royal Arrow.

      Sorry you went through this insertion of ball bearings into a Royal in this manner. For the future attempts, there is a re-creation of a custom tool for doing this sort of operation which also includes some repair manual details: https://www.m-morren.nl/product/17071027/royal-bearing-guide-ball-feeder-tool

      Lucas Dul also has a video that might help: https://www.youtube.com/watch?v=a_PONcT8HHI as well as some discussion of using straws at the 21:40 mark in this video: https://virtualhermans.com/lucas-dul

      I have my work cut out for me withHemingway, since he used many type-writers: a gigantic Royal No. 10 desk-top with glass side panels from his earlyKey West days, an Underwood Noise-less that helped him fi nish For Whomthe Bell Tolls and fi le dispatches fromhotel rooms while he was a World WarII correspondent, and black matte Roy-als from the early 1940s—especiallythe Quiet DeLuxe and Arrow—he fa-vored while at Finca Vigía in Cuba.

    Category: The Essence of Composition

      You have another function g that takes a B and returns a C. You can compose them by passing the result of f to g. You have just defined a new function that takes an A and returns a C.

      That clears that. Arrow A->B and arrow B->C are not necessarily the same arrow (function).

      Okay, so what are we doing here? Category is a set (?) of objects with arbitrary functions between them. The only property that this needs to satisfy is one of transitivity.
