i just recently started building wooden cups for grado's and to be honest i dont understand what i'm doing.
heres a link to my first attempt at making wood cups.
so my question is this. is it ok to have thick walls for the cups? as of right now i'm using cnc mills to create my cups and soft woods like mahogany so the wall needs to be alittle thick to survive the milling process :( i'm at 5mm right now and am trying to go thinner.
secondly where can i get new drivers that will work in these better? i'm in california and i'm having issues finding any dealers in the states :(
