Currently I'm working on a DNA30,and I've built an SX chip mod.I've got a friend that wants me to try and build him a sub ohm box mod,and I have a couple of questions,as I haven't built one.I fully understand the basics of building a semi mechanical mod,and don't really have the means or know how to build a full mechanical mod.I plan on using 12 or 14 AWG solid copper wire,a new fatdaddys spring loaded 510,and a Hammond 1591b plastic box.First,what switch do I need?Seems a lot of these boxes are using 60 amp switches.Is that the best and safest route to go,and where is a good US source for one?Second,I have a Keystone dual sled for 18650s,will this work for a super sub ohm box,or should I make copper contacts?I could make the positive contacts with parts from Home Depot,but I don't think there is anyway I could make springs.Is there another option for negative contacts,or where could I get heavy duty copper springs at?I want to build this as heavy duty and safe as possible,cause I don't want this to vent if he goes super low.Thanks for all the help guys.
