Dan how big are these blanks you are turning? Friend of mine has one of the Ci1 tools and he is always breaking off tenons. I don't like the tool myself because when you take a bite it puts a tremendous load on the wood in my opinion. With Hemlock, fir, pine, etc. they are soft woods and when green I would think you would be putting a awful strain on that tenon. My tenons are generally 1/4" or so but the diameter is fairly small. I was taught that the jaws of the chuck should have less than a 1/4" space between them so that when you clamp down on the tenon they are almost shut. If you don't you are only gripping on 8 points which doesn't give you much holding power. Try your Ci1 on something like maple or walnut chucked up to see if you have the same problem tearing off tenons. If you do I would say you might be getting to aggressive with the tool. Just my humble opinion. Give me my bowl gouge.
