Good advices for a newbie (threading tools lathe)

[rendoman]

I went to the dark side 6cm drill buffer, and a home made not good small buffer for the inner part... i hope monday i will find some better commercial new one. polishing with drill maybe it's the better way to do this job, now the horn is shining more than in photo. I hope i'll finish the first flange and do some test! See you on the next episode
