Hey all just a quickie here to tell any of you that know any one at a plumbing shop that cut and thread their own pipe. They will have old worn out HSS threading dies. If they haven't trashed them you can usually have them for the asking and most of the dies will make great tooling bits. Some of them will be on the thick side so a little grinding is involved to shrink them to fit your tool holder and then grind to whatever angle you what or need. The good part of this is if you mess up you'll have plenty of material to try try again. I have a few and have ground them to tool holder size with a 4 1/2" grinder. Then to the bench grinder and finish on a belt sander for the angles I think will work. BTW most fire sprinkler companies have them also.
