Well, I got the two antibacklash nut mounting blocks I needed to make for sure done this morning. (The third I may be able to mount directly in the slide by machining the slide itself.) I gave up on all the fancy stuff for tapping those 6-32 holes and just used a regular flat handle. The key seems to be that you take it in until it gets a tiny bit more resistance, then back it off a full 3/4 turn every time. If at 3/4 turn it is not spinning freely completely remove the tap and blow the chips out. I tapped 4 holes with the same tap with no problems. All by hand without a hand tapper tool.
