so I'm in love with changing out my cone colors on my eGo to match what I'm wearing, totally metro I know... I use a 901 to 510 adaptor on my SD mkII, and was thinking it would be awesome to be able to add a cone to my SD by adding some width to the adapter, and threads that would match the threads on the cone. I have access to machining tools to make this happen, but I need to know the thread count, and pitch on the cone to make it happen. Anyone know? I think the SD looks even more wonderful with a cone on it, but it needs to stay in place to work!!!
