A 30 minute x-axis mod to reduce chatter

I love this idea and I have been ready to upgrade to a Dewalt 611 but this mod had been putting me off of the upgrade for lack of drill press and I was about to buy one of them as well to be sure the holes were done right. If this works just as well then it will save me a big headache of tearing the machine apart and potentially screwing it up. Thanks! I wish they would sell a reinforced axis now that the standard spindle is the 611.
