Since I was asked what I use for hole punching, I use the old fashioned pen
nibs used for pen and ink, turned backwards so the part that secures it to
the pen is exposed (a sort of half cylinder), and secured with epoxy and
fishline onto a dowel or pencil. I may wrap some tape around the end I
turn it with to make it more comfortable to turn. A quick poke and turn
and a nice clean hole is made, of a size to be functional but not too
likely to fill when dipping in glaze (or I blow them out immediately if
they fill with glaze).
I did try mounting one on a metal screwdriver bit to use with a cordless
drill, but didn't find it to be significantly faster, not to mention more
unwieldy, particularly in drilling on the inside of colanders...

Best hole punch I've ever found is a brass rifle cartridge. Get one
that's necked down like a .30-06 or a .270 and cut the back end off.
Of course, I'm talking about one that's been fired. If you just use a
straight brass tube, it takes too much force to push clay all the way
through it. But with the necked down cartridge, it only has to go a
half inch or so and it no longer has any resistance. Clay just falls
out the back of it. Just hold one finger behind the clay, push it
through and twist a bit. Perfectly clean hole every time.

For smaller holes. A telescoping metal car radio
antenna, collapsed & sliced at an acute angle with a
fine saw. Several sizes. No handles necessary.

I like this one - one tool for any size hole you want and the plug of
clay doesn't get stuck in the tool.

When I was making light fixtures with decorative perforations and designs,
my best perforators were artist scalpels for linear holes (way less drag
than exacto or fettling blades) and short lengths of brass tubing sharpened
with a file for round holes.

In my teacher's workshop, we used a metal strut from an umbrella.

I had read somewhere that if you take a piece of bamboo and shave the end
off in a slanty angle, (so it will penetrate the clay smoothly) it will
make nice holes. The size of the hole is determined by the diameter of
the bamboo you are using.
Tried it and it works like a charm.

Hi All,
I could use some tips as to how to make a tool which would countersink the =
hole in once glazed colanders. I see a small grommet in my future, and a sm=
all dowel. Perhaps it's Lee's umbrella strut. My reference can be found on =
p. 97 Single firing the Pros and Cons by Fran Tristram. Going to venture in=
to some single firing on some ware and I really admire Andrew and Joanna Yo=
ung's work. Currently use a sort of half round piercing tool which I turn t=
hrough a circle and remove core, like umbrella strut Lee Love suggested, an=
d blow like mad after glazing bisc to clear holes and then follow up with a=
tapered brush tool which I dampen, wipe on sponge to remove excess water, =
insert to clear blocked hole and then swish to clear brush and repeat. It =
works. It's routine on some jobs. I like the idea of piercing after once gl=
azing and the look of the countersunk diameter showing the light body again=
st a dark glaze is very, very nice.

I use a cytobrush, an endocervical sample collector.
Got a few packs left over from a GP clinic I worked in
years ago. Also handy for cleaning glaze out of squirt
bottle nozzles.

Ages ago in London I learned to harvest the spokes from broken =3D
umbrellas, sharpen up one end, and use as hole punches! My friends =3D
gathered broken umbrellas whenever--quite often--there was a howling =3D
wind and heavy rain.
In NYC at a cork store, I learned how to make a hole punch for corks. A =
=3D
punch I have used for clay.
Cut the end off a copper pipe of the type uses as inlet for sinks. =3D
(About 3/8" OD)
Make the cut at a about a 45 degree angle Not too hard if you thread =3D
the pipe over a dowel of same size and clamp gently. When the pipe is =3D
cut file the
longer end from the outside so as to sharpen it. With dowel removed =3D
drill a hole through the top of the pipe about 1" down. Take a big nail =
=3D
and stick it through the holes.
Your cutter now is kinda a T. The nail helps you turn the cutter as you =
=3D
make the hole..either in clay or in a cork.

Ive been away teaching and havent had a chance to read all of my
Clayarts.... so if this has been mentioned already , I apologize...
but I use straws....push in and twist and they make a nice clean cut.
I cut them into shorter lengths.... and they come in all kinds of
sizes from HUGE for frozen drinks to tiny for coffee stirrers.
After it fills up with clay, I just grab another one.... and set
the used ones aside to let the clay inside dry .. Then I roll them
with my rolling pin to crush the dried clay inside , dump the dry
powdered clay into my slurry container... and the straw piece is good
to go again .
