Right now I have a fused Clapton 24g nichrom80 core wrapped with 30 ga kanthal and its just 1 coil but the single airflow hole isnt like the long slit oval thingy and for the single coil its just a small circle. any tips on how to have the airflow set to open it up more with one coil or should I just bite the bullet and drill out the one side with a 2 3/32 holes and try to file it open up to create the small holes for dual coil. Sorry for the long post and run on sentences but any help is appreciated thanks.
