[QUOTE="Trickymissfit, post: 624729, member: 25383"] if you look at the female threads in the reciever under a strong light and magnifier, you'll probably see at least one line running lengthwise, and usually two to three. Those lines are cause by the chips being broken off when the tap is reversed. When this happens all backlash in the spindline is reversed causing error. You can tap threads accurately, but it's usually a one up deal. When you use a tap in a machine (in this case a machine center), you add into the fact any error in machine alingnment, spindle bears, and error in the spindle itself. When you do the samething with a boring bar in a decient lathe you only take in the error of the bed of the machine and quality of the spindle bearings (not much of a factor here). The one otherway to cut the female thread, and also a little more accurately is with a thread mill. The operation is a little slower than the other two, but the thread form is far more accurate. The slower the operation the more money is involved in the part. gary [/QUOTE]
