I finally bought the new ER16 spindle for the Taig mill from Carter Tools. Shipping was fast & trouble free, and the service was great as usual.
The 3/8" endmill holder I was using before (which screwed on to the spindle nose thread) had close to .0015" of total runout on its best days. Measuring the runout on my best 3/8" shank endmill held in the ER16 collet with an Interapid DTI showed less than 1/4 of a thou of deflection (.00025"). This makes for better than a 500% improvement in accuracy; I feel that this upgrade is well worth the money spent.
