A 2" dial indicator, secured to a sliding clamp similar to the carriage stop, is used for accurate carriage positioning. It is very useful for turning lengths up to 2", and can be positioned anywhere along the bed. Rather than reading cumulative distance on the dial, it is positioned to zero out when the desired length is reached.
I use the compound when increasing the depth of cuts when threading. After a cut, the cross slide is backed out enough to clear the threads when returning to the start position. The compound (set at 29.5 degrees) is fed in the desired amount for the next cut, and the cross slide is returned to the starting position. The next pass is then cut. This addition provides a very positive stop when re-positioning the cross slide. It is fastened to the cross slide using the tapped holes normally used for the follower rest. A SHCS is inserted into the threaded hole in the notch when threading. It can be used for internal or external threading.
