I've got both the #4 and the #41 (larger diameter) boring bar blocks, and have the same issue with orienting insert boring bars. I should also give it a tryto see if I can drill & tap them. While I'm certain it can be done, I just don't think I can afford the solid carbide drills and taps it may require. Those things are HARD.
If I can find time to get over to the shop I'll give it a go. It's dad's 80th on Friday and we've got a little thing going on for him on Saturday.
