Guess I'm spoiled, then.

The bottom rod with the two clamp on collars pops
the carriage out of drive in either direction.

It even has a fine adjust on it, but only on the "towards
the headstock" side. I really like having the direction
reverse right on the carriage, too. Makes left-hand
threading a breeze.

Speaking of threading, does anyone else turn inside
threads by running the tool upside down on the far side
of the bore, rather than rightside up cutting towards
the operator? Probably just me, but I'm more comfortable
seeing what I'm doing that way...

Nope, the last time I ran with the tool right side up on the far side
with the lathe in reverse. That way, the tool was coming out of the
hole instead of going in. This was a 5 tpi thread, so even at slow
spindle speed, it moved pretty quick. I reported on it a month or two
ago on this newsgroup. Look for broom handle thread.

That's a common trick used by those of us that have worked in commercial
shops. Be aware that where you place your compound isn't the same as
when
threading towards the headstock. You likely understand why.

Right, I reversed it (hand wheel nearer headstock). But since this
was an acme thread, only 14-1/2 deg. I wasn't worried about the angle
too much, because broom handles are far from perfect anyway. I had to
modify the profile by rounding off the crests to mate with the molded
or cast handle threads.

Very good, Pete. You'd be amazed how many fail to do so (even guys with
experience). It often leads to problems.
