I have found that many things I go to machine on the lathe end up being very close to my whirling chuck. This means that I have to be extremely cautious when taking a cut parallel to the axis of the rotating part so as not to run my compound rest or cutting tool into the chuck. Since I always turn the lead screw manually, I should be able to clamp a physical stop to the lathe ways to stop the carriage travel at a safe distance from disaster. The people at Busy Bee are anxious to sell me stuff, but they don't know s#*t from mud about what accesories are available for the things they sell. It would seem to me that anything which clamps to the lathe ways would have to be somewhat of a custom build, suited to the lathe it was going to fit on, but perhaps there are generic ones available.-Any help would be appreciated.---Brian
