Default Source for 5/8-27 rethread tap and die?

Okay, it'll probably be cheaper to just buy some new mic stands, but being
penurious, I'm trying to repair first.

I had a couple of mic stands go over when they got caught by a tarp that
came loose in a windstorm. The booms left fragments of something (zinc,
maybe? Britannia metal? what the heck does K&M *use* in their booms
anyhow?) wedged in the threads on the stand uprights.

McMaster-Carr has taps at around $30 and a die for $51.71. Is there a
cheaper source that anyone knows of (considering that I don't need to do a
lot of this stuff)? Is there an alternative that I'm missing ("Oh, just use
a #3 Finster grommet in a Vise-Grip.") Or shall I just chalk it up to
experience, strip the stands for usable parts, and go buy some new ones?

Thanks.

Yes.

They'll be all loose & wiggly-wobbly if you tap them & rethread, so ****
it... get new ones. It'll cost you less than the toolings if you don't have
them already. Besides... do you really WANT to put a $3,000 mic on a stand
that could act like an oilfield pump in the Permain basin in the mid-70's
at any moment?

That's about the last thing I expected to read when I got up today.
Nice analogy.

http://mscdirect.com has imported tap and die for about 1/3 that.

However, take the warnings to heart. Mic stand threads are "rolled"
which means that the threads are pushed up and the threaded portion is
larger in diameter than the tubing stock. A die cuts threads, which
means that the outer diameter of the thread is the same as the
diameter of the tubing stock, and the bottom of the thread is smaller.

There's a fairly wide tolerance on the threads used for mic stand
hardware, but it mostly works against you when trying to cut new
threads on the thin-walled tubing. If you want to cut a 5/8" thread,
you need to start with stock that's larger in diameter than a mic
stand tube (which you ain't got).

MSC has them for a good bit cheaper. You don't need the set of three taps
either; at the very least you can skip the bottoming tap.

Neil, thanks for the vivid mental picture.

Point well taken. In about ten minutes I'll have a pile of mic stand parts.

On a related note, does anyone know *why* such a peculiar thread size and
pitch was picked for mic stands?

I haven't bought the tap, but I've done a lot of work with both 5/8x27 and
7/8x27 dies without any problems.

One thing, the dies are somewhat adjustable for diameter and that will stop
looseness if set correctly.

No, but it makes a certain degree of sense to have a fine pitch thread
so it won't unscrew easily.

There are a number of other "standards," many of which are still in
use in other countries.

It wasn't picked for microphone stands originally, it was a standard electrical
thread pitch.

It just got adapted to microphone stands.

Bruce Black out here in sunny Southern California is the complete source
of all things cool for care and feeding of Atlas & AKG mic stand parts,
as well as many other great audio gadgets. Plus, he's a really nice guy.

He ahs all manner of replcament parts, all better than original, as well
as taps, dies...well, just go to the web site and look.

As an aside, last week I tried ordering some mic stand parts from the
venerable Black Audio, the place you could buy almost anything related
to mic stands. He's in the process of folding the company and didn't
have the things I needed. Boo hoo!!

You can get them from MSC Industrial Supply...

They carry everything you can imagine that relates to machining tools.
