That won't work on the Tuning Cap for the Philco 80.

I made a Bunch of those a few years back. I used Nylon Rod, bought 8 foot lengths at the time tapped the thread and made as you did. They do work very well, but not for this application. The slotted screws prevent you from putting a driver like that on there. I only have one left of the dozens i made, they are a popular tool.

Thank You for your Kind offer.
