I must be dumb. What holds the tap in the holder & why hex stock? I see a little dimple on some of the holders are they set screws?
sorry to be so slow.
thanks
Yes the set screws are to hold the tap on the square.
The hex stock is to be able to finish the tapping with an open end wrench. I start the tap in the mill
by turning the power on and with the end of the tap near the start of the hole, turn power off and engage
the tap with one hand on the brake and feed the tap in as it rotates when it gets in far enough, if it's
still rotating, hit the brake to stop. Sometimes it's not in far enough so lock the quill and crack the jaws
loose and finish with a wrench. If not using a keyless chuck, retighten chuck and reverse toback out,
otherwise have to use the wernch to back out.
Now I'll admit the first time or two I saw that being done by a friend I was more than a little scared
but after a little "screwing up of courage" I tried it and WOW what a way to tap. Peice of cake.
