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

The adjustment points for the on-feet and motion on a Royal Arrow (and similar for the Royal Quiet De Luxe). The outer screws (one on each side) is for the lower case and the inside set is for the upper case.

I love that Joe sets up a camera inside the case of the Royal Arrow to show how the metal fixtures on the case dovetail with the machine. In one instance the piece on the right has been bent while the one on the left properly tucks the carriage return arm inside.
