510 Pos pin

[fasteddie600]

I used M4 threaded brass rod for the 510 on my little woody and it sits just right size wise within the 510 and is big enough to cut a slot in for adjustment if required.

Not sure it is worth all the effort doing copper IMHO, brass works almost as well and doesn't need as much cleaning. Silver plated would be the ideal, not convinced you would gain that much though.

When messing about experimenting with various metals for the centre pin on a box mod, the difference between stainless steel, brass and plated screws couldn't be measured with my limited range of equipment so I quit fussing and focused instead on the rest of the mod/connections.

You'll be better focusing on the Physical characteristics of the pin material rather than it's conductivity, a pin that doesnt sit right or is too soft will be far worse than any amount of difference in conductivity - voltage drops on copper vs brass is actually in the Microvolt range (0.00001 volts) anything less than about .1v is not perceivable whilst vaping...
