It's driving me crazy! Two blocks in a row today had tiny sandpits in the chamber. One block is grade 1 Manno, the second one is grade 2 Mimmo. I tried to re-drill one chamber with a wider brill bit hoping to remove a sandpit. The bit was shaking at first (I fed it too fast) and now I have an oversized chamber with the same sandpit and a couple of bandages on my hand (lesson learned). My bin with rejects getting bigger every day and I have enough shop pipes already.
What do you usually do with those blocks and how often do you have this situation?

Re: Sandpits in the chamber
The pit in the first picture would need investigating, the spots in the second picture look like nothing to worry about. If you reject a pipe based on a few black spots in the chamber you will never make a saleable pipe.

Re: Sandpits in the chamber
I knew I'm too nit-picking!!! So I will finish the second one and now I will be less picky about such imperfections.
Thanks a lot, Chris!
