Hello! I think one reason the forum has such low activity is new people have had trouble joining from my understanding. Anyways I try to check back on this thread from time to time but with n activity for so long I got lax.
ekaggrat, yes I use pulleys with 4mm bore. I do use 18mm aluminum spools you have to get the stringing just right to get good spooling without overlap. Did you get thosee owrking eventually?
I'll try to keep an eye out for questions/suggestions here
