I bought mine from Creative Industries at
http://www.creativewheels.com/products/Grinders/ . I heard that Rio Grande
Tools also has them, but haven't compared their prices.

Eric -
In my experience, an abrasive flap wheel on a bench grinder works best fo=
r
this smoothing the bottoms of pots. You can find more information about
them in the archives. You'll find a decent bench grinder at Home Depot o=
r
Lowe's for about $60-$70. Go to www.grainger.com and enter part #3DV14 i=
n
the search box and it will take you to a 6" by 1" 80-grit flap wheel.=20
Notice that it has a 1" arbor hole, so you also need to order the adapter
bushing set to make it fit the 1/2" shaft on your bench grinder. Enter
part #3DV21 for the adapter set. A flap wheel and the pair of adapters
will cost you less than $25, so for less than a hundred you can get the
whole works including a bench grinder. The combination of a grinding
wheel on one end of the bench grinder, and the flap wheel on the other en=
d
is an ideal setup, good for so many studio needs such as sharpening and
shaping tools.
Some people complain of a slight discoloration on porcelain where the fla=
p
wheel is used, but it works great on stoneware, even white stoneware
bodies, and it is about the best thing there is for smoothing rough
surfaces on the bottoms of wood, salt, and soda-fired pots.

Does anyone have a source for the flexible drum grinders for
finishing off the foot rings of bowls and plates and the like? Or a
suitable option.

Eric, this is more properly called an "expanding drum sander".
A rubber wheel is made with a network of holes, and centrifugal
force makes it expand to hold a sanding belt tight in use.
I got mine at a jewelry supply house (now out of business), and
any jewelry supply should have them.
As Alisha Clarke wrote, Creative Industries, the potters wheel
company also sells them.
The best prices I have found for both the drum and the sanding
belts is Dad's Rock Shop: http://www.dadsrockshop.com/
I like using this tool for finishing the bottoms of pots and use it
for most of my work, but it is best to have options for pot bottoms.
Sometimes, a flap sander (Vince's favorite) works better. If you
have a grinder motor you could have one on each side.
Sometimes a flat surface sander works best, such as when a piece
with feet rocks and you need to level it. Look at the "grinding
disc" that attaches to your potters wheel head, also from
Creative Industries,

Dear Vince and Eric;
I ordered a set of diamond laps from Master Wholesale in Seattle:
http://www.masterwholesale.com/details/1122498368.html
The set of 70, 120, 220, & 400 grit pads is all one needs to finish
the bottoms. If one uses a flap wheel first and encounters the
marking-on-porcelain problem, the 400 will take that off fast. Use
them wet for best results, and don't use much pressure......... the
diamonds do the work, not force.
Cheers for baby-butt bottoms!

DEar Gail;
If you open the link I gave, you can see that they are plastic sheets
impregnated with diamonds and glued to a hand-sized block of stiff
foam. They work a treat.

Hi Eric,
I would discourage anyone from dry grinding - it's better done with water
to keep the dust down.
I usually use a soft stone with the pots upside down on my wheel. Once the
stone gets a few slots ground into it you can use them to grind faster.
I've found the knife sharpeners - with a wood handle work just fine.

What they use here in Mashiko, I think works better:
you take a whet stone and bust it in half. The size fits well in the
hand. You dip the stone in water, then move the stone on the
foot in a circular motion, first flat, then inside edge of foot, then
outside. Sponge the grit off after you polish.
All pots are finished this way. At the pottery festival,
potters often put a finishing polish on the feet. The ringing sound
of stone on foot is an announcement of a sale.
