Got in some threading inserts I bought off eBay to fit the Valenite Rigidex RD 05S 531 boring bar that I showed in Post #270. A pack of ten for $29.99 was a good price.

I also got the print for the boring head that I'll try making for it so I can use CCGT21.5x inserts. I can't post the print because it's proprietary, but suffice to say it will be one of the most technically difficult parts I've ever attempted in the home shop. It would be easy enough on a 5-axis machining center with some pre-machining and fixturing, so to tackle it with a tilting dividing head will be a test of my waning brain power. I fully anticipate two or three "nice try" screw-ups before a "usable" one is completed.
