I have a few pipe taps for pipes ranging from 2 inch NPT to 5 inch
NPT. They are big, very heavy, and grimy, slightly rusted and very
dirty.

My question is, can I clean them with a motor mounted wire brush, or
will it be somehow deleterious to the cutting edges.

Boy, Tom Gardner couldn't stand to see you abuse a wire brush this
way!

With a little care and common sence, I don't see why not. That is run
the brush away from the cutting edge.

A brass brush would probobaly be the safest if your concerned
about the cutting edges.

Are those taps carbon steel or high speed steel ?

I would never use a wire brush on a tap or die.
Any sharp edge will be dulled.

Use a fiber brush. Use a part washer or transmission fluid or
the like to clean.

These cut strong iron pipe. If really nasty - parts washer or a
container with sink dish washing soap - and a fiber brush.

I'd agree. I was taught not to even clean bolts using a powered wire brush.

I can't imagine degrading non-critical bolts with a wire wheel enough to

I've never heard of it, but who knows?

Iggy, I've cleaned and sharpened taps by hand for around 40 years. Unless
you're using them in volume commercial work, it's probably quicker than
using power. That is, unless the taps are really shot.

I use a hand-held bristle brush to clean them, and (usually) paint thinner
as a solvent. I sharpen them by clamping them in a vise and running a round
slip down the gullets, leaning on the cutting side. My slips are in two
grades of aluminum oxide and hard Arkansas stone. I have around twenty of
them in different sizes and shapes.

It's quick, if you don't let them get too bad. You'll kill a lot of time if
you can see rounding on the cutting edges with your naked eye. That's when
I'd send them out, if I did that much work with taps. But if they're too
rounded, they're shot. You'll never get a true size out of them again.

Ed, keep in mind that they are tapered pipe taps. They are not
straight. "True size" does not make as much sense for a tapered tap,
if you think about it.

I will go today to a tool grinding place and I will price sharpening
them. I am sure that it will be cheaper than me doing it by hand.

I will then sell them as "resharpened taps, ready to be used".

I will post an update for this.

Perhaps not, but uneven metal removal will make some flutes cut deeper
than others.

I got an acceptably sharp edge by grinding the (formerly) curved
relief between centers on my surface grinder, with a spring finger
locating the gullet side of the edge. Grinding either the taper or the
gullet doesn't affect the thread diameter on a straight tap since it
only moves the tapered cutting surface a short ways into the full-form
threads. AFAIK these don't have any back relief.

Great,

Something else to keep in mind for future reference: Most people just
sharpen the chamfer on the cutting end of a *straight* tap. That's easy --
you do it from the outside, not the inside of the gullets. They'll do that
three or four times before going after the gullets.

But I try to sharpen them all the way up, because I do them by hand, and I'd
rather keep them very sharp all the way along the edge so I never have much
metal to remove.

Sharpening taps is not rocket science. One simply sharpens the leading
edges of each group of flutes. Nothing more, nothing less.

Boy, Tom Gardner couldn't stand to see you abuse a wire brush this
way!

With a little care and common sence, I don't see why not. That is run
the brush away from the cutting edge.

My question is, can I clean them with a motor mounted wire brush, or
will it be somehow deleterious to the cutting edges.

i

Exactly! Besides, I would think the corrosion has already damaged the
cutting edges to some extent.

Hm...

I am thinking, I should take all these taps to a tool grinding outfit
in Addison and have them resharpened, prior to placing on ebay.

Do they chemically sharpen taps as they do files?

I'd agree. I was taught not to even clean bolts using a powered wire brush.

I can't imagine degrading non-critical bolts with a wire wheel enough to
matter. I do make special brass knot-type brushes for Sikorsky rotor bolts.

Are they used to clean up dirty threads before they're unbolted
through an expensive and critical casting/machining?

The brushes remove loctite or such. Then the bolts have to be
re-certified before being put back in service. These bolts are
thousands of dollars each and aren't allowed to be touched by anything
steel. They aproched me to find a solution and they loved the method I
came up with! I got to talk to some of the engineers that build the
Blackhawks and they sent me some pictures and tech specs that were
redacted...how cool is THAT!

In CA, some do. (I never saw it work, tho.)
Here in OR, we take diamond hones to dull tools. I have an array of
DMTs and EzeLaps, plus a Chiwanese cone.

(I left CA in Feb of 2002, Tawm. Keep up, will ya? I guess time passes
differently for you lesbians in Cleavage, OH.)
