Does anyone know what the thread size is on the Jr. gent centerband coupler? I need to re-cut the threads or dis-assemble and replace the centerband either way I am going to have to make some kind of purchase.
The threads area not standard ISO or metric threads. They're triple start, for starters, so re-cutting those threads will only be possible with a triple start tap - and those cost hundreds. I suggest just replacing the part with a new one.
