Elizabeth,
I'm glad you've found a way to tap center that
works. And, I agree, it's only one of the ways to get
the job done.
However, I emphatically don't agree that a wet
wheel head is a requirement to tap center. The water
does seal a piece down, along with an even rim, as you
note. The water can make some pieces slide more
easily across the wheel head. Tap centering greenware
on a plastic bat is easier on the rim than a metal
wheel head. However, you can tap center with the wheel
dry. I promise! Works the same! :-)
Keep making your good art!

Dear Dave,
You were there! You saw the light bulb go off on my
face. And it was the water that made it work for me.
I am metiiculously picky with regard to centering. I
have developed a method of trimming that hides this,
as I don't like the way it looks in reality, but get
compulsive about it being perfect when I let my inner
inklings guide my hand.
Tap centering dry will be a new goal for me.
I will try it on plastic this very weekend.
But if it moves...even a tiny bit...water.

I posted my excitement of learning to tap
center after coming home from the potters
conference in S.C. I used a plastic stadium
cup with water. When I had eight mugs to
trim, I used a bit of water--just enough
and not too much. Just as Mel wrote, the
water helps keep a vacuum.
I'm still at the point where whenever I sit
down to throw, I practice a little with the
plastic cup. It's a matter of getting a feel
for it--and trying something new after a
dozen years of doing it another way.
When trimming bowls, I'm now tap centering
but using wads of clay to hold them down
and not using any water on the rim. I found
this way worked better for me. YMMV.
