Note that in your Subject line, you said 0-80, not 00-xx.

Yes! Don't need to go further than 0, thanks.

I suspect that it would work well, with one possible exception.
The torque limiting clutch might not go down quite low enough. Normal
practice with the TapMatic heads is to start with the clutch fully
loose, and slowly adjust it with a *brand* *new* tap until it will feed
all the way though. Adjust it just a little beyond that point, and when
the tap starts to dull, it will slip again -- warning you to change the
tap before it breaks off in a workpiece.

As for the 0.140" self feed (this is at single speed, BTW, the
higher speed is only when backing it out) -- I have my own preferred way
of setting it which does not require measurement. If you pull out on
the tap chuck you reach a point where you can rotate it by hand and turn
it about 1/6 or 1/4 turn you will reach a point where it will rest on
the dog clutch extended. Then adjust the stop on the drill press so it
will stop before you run out of threads on the tap (leave a couple spare
threads unless you are working with a deep hole). Then tease it to
rotate a little and it should snap back to the engaged position to
reassure you that you set it while the dog clutch was released.

When using it, if you pause feeding the dog clutch will
disengage and start going clack-clack-clack. Feed a bit more and it
will start threading down again. When it reaches the stop, you will get
the clacks again, and that is the time to let the quill back up slowly
(especially slowly with an 0-80 or smaller) to back it out. With
something like a 1/4-20 it will back out a lot quicker.

At that price, I would get one, and try it with your #00-96 was
that the pitch for a #00?

0-80 is all I need. I'll get one of the little guys with my next
order, thanks, DoN.

Enjoy,
DoN.
