Sharp, lapped inserts or brazed carbide tools are awesome for fine cuts and pulling off a nice chip with low tool pressure. I learned that from Robin. Renzetti, (Go figure eh?) How come you never told me I could mount my Mini-Cool to the back of the vice⁉😁🤣 I wonder if the act of removing and reinserting the boring head influenced the location of the point of the boring insert a few tenths one way or the other and the second hole bored a different dia? Or was it tool wear and pressure?
LMAO i will be a bit snarky right now, but the WHOLE IDEA OF PRECISION STONES is that once you stone your surface, you don't have to smear it with your hand afterwards. We have to get rid of our habits from time to time :D
Nice work! I watched Rob Renzetti's video on making a solid tool post to address the same issue and will probably do that. My tool post will rotate on the compound as there is no index nor T-slot. Until I make the new one, a butcher paper washer (not a typo) prevents the tool post from slipping on the compound of my lathe for the tool pressures I use. Renzetti's video is here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pG3YSfgyJPI.html
