Far be it for me to tell another man that he has a nice tool, but....
That's one helluva nice threading bar and I envy you that. I'm limited to just the ER/IR 16 size inserts for now. I can envision adding the larger 22's when the right tool appears on Ebay for the right price.
DaveH, if there's anything you wish to know about the triangular lay-down threading inserts I'm happy to help. I will tell you this: It can be expensive to get into them, and you have to weight the cost-benefit ratio for your own situation. The benefits include beautiful, perfectly ISO/ANSI-compliant threads (when using full-form pitch-specific inserts), and reliable performance.
Apart from the pitch-specific full-form (a.k.a. "cresting") inserts, there are A60/AG60/G60 "partial profile" inserts that are capable of making threads of a wide range of pitch, though the sacrifice is that they have a .002" (A60 & AG60) or .007" (G60) tip radius and they don't create the thread height themselves as the full-form ones do. The A60 or AG60 are the ones to have no matter what, so you're not stuck not being able to make a thread if you don't have the perfect cresting insert on hand.
That should be enough to generate questions!
