Casting Custom C Ring Tools for Obscure Fountain Pens (III)

Progress vid on the metal-epoxy-as-disposable-C-ring-tool tests. For those who prefer text to youtube clips, conclusions are:

  • Red rubber grease and teflon tape have prevented the epoxy from binding to the threaded boss whilst curing in every instance.
  • The epoxy made a good cast from metal and plastic boss dummy run threads, and of the suspected BHR threads of the fountain pen's boss itself.

Apologies for the less than lively audio, bit of a cold coming on!

A Suivre:
I guess there's nothing left to do but try the tool on the pen (gulp).

  1. Hi,I'm interesting in this C ring,how can I get one?And I noticed the thread on the Japanese eye-dropper pen is unremovable,if we try to remove it from the barrel maybe will cause the crack of the barrel,how can you prevent it?
