hey guys. after a few months of vaping on regular tanks i decided to get into rebuilding. i don't want to drop too much money right away in case i don't like it so i went to my vape shop yesterday and picked up some kanthal and an igo-w (still have to get cotton. if anyone can tell me what kind of cotton to get that would also be greatly appreciated). i was all excited to start rebuilding until i noticed how tiny the air holes on the igo are. i popped on a drip tip just to test the air flow and it is extremely tight. definitely not going to be big enough for the type of builds i want to do. i watched some videos and everyone says that the steel it is made of is very tough and can easily break a drill bit. i also don't have an actual drill press so i don't want to just go at it and ruin the thing before i even use it. does anyone know anywhere i could go to have them drill the holes out for me or to use a drill press with strong drill bits? i don't know if a place like that even exists. i was thinking of going to home depot and asking someone in the hardware section to do it but i don't know if they will or not. any help is much appreciated. thanks guys
