I was roughing out a larger piece for a HF, there were a lot of bark inclusions on the piece, I checked it for metal, as it was urban wood, so could have a few nails in it, it did not.
I was roughing away nicely and all of a sudden there was a loud crack, and the piece snapped off the tenon, bounce off the wall, and then trundled across the floor into the far corner.
I was wearing my full on Triton Power Respirator, but I was well clear of line of fire, so only my nerves were damaged
The only damage was to the tip of my Ci1 rougher...........

I'm fairly sure that I hit an embedded rock, there was a "hole" in the blank, that was rock shaped, about the size of a golf ball, but I've yet to find the rock.
I just turned the insert insert and started over.......
Oh yeah, the #1 side of the insert was getting dull, so it was good I changed it, but then I counted, and I've roughed out a total of 27 bowls with the first edge Now they were all green wood, and most were 12" to 8" in diameter.
I have found that it is quicker for me to grab my 3/8" bowl gouge to do the last cut to smooth out the rough out, than do the finishing cut, which does work, but take more time, and time and ease of use is, for me, what the Ci1 is all about.
