Hello everyone, I just completed a copper mod and I can't figure out what I can use as a top cap/atty base. The part where the 510 fitting sits in. The way I have wired the switch forces me to use a non conductive material so brass, copper... are out.
In this picture I found a rubber grommet in my parts bin, at this point it's just pressed in there. The inner diameter of the tube is ~16mm or 5/8

I'm thinking jbweld and then sand to shape
I also found something while searching online, they're plastic plugs used in furniture legs.

Any help is appreciated Thanks
