Well I made a 4.5 inch flange die tonight and am less than pleased. It doesn't make the flange very good. I cant see if the plastic is giving under pressure or what. Anyway I will not be making anymore, sorry to get your hopes up (and mine) but I just dont think they are worth the effort and mess. It looks like I got 2 feet of snow on my lathe. I will try other materials and keep you up to date. Sorry Jesse.
