One of the best things we have bought for our studio
is a flapper wheel for our 6" bench grinder. It is a
wheel of hundreds of pieces of sandpaper. It works
great for cleaning off the bottom of pots. Makes them
as smooth as a baby's bum.
We had to have a neighbour make a bushing so that it
would fit on the 6" grinder.
We bought it at Art's Tools so I think most good tool
places would know what you're talking about.
Joyce will want two- wink, wink,
Cheers,
Tony

Do you use it to clean the bottoms before you fire or after?
Thanks

I make my own flap wheels for wood sculpture but had never used them for clay.
They have the advantage that you can get into tight corners and deep
grooves without distorting the contours of your piece. the pieces of
sanding material just flows around the high spots.
Here is a low-cost way you can try out the idea. I used shafts for hand-drills
that are made for grinding wheels from the local
hardware. I had a couple lying around so I took the grinding wheel off one
shaft for this project. The procedure could be used on a bench grinder I
suppose. Because of the speed of a bench grinder, I would hesitate to
build a 6 inch diameter wheel, perhaps a three or four inch one to start.
For abrasive, sandpaper with cloth backing seemed to work best.
Old belt-sander belts are great.
You need multiple strips fof a length equal to the wheel diameter
you want. The widths should allow you to cut or puch a hole in the center
to slip over the shaft. Be generous, cut a couple of dozen strips.
Put on a big washer first to hold against the center of the strips. Slip
half of the strips on with the sanding surface facing the washer and the
next half facing the other way. add a end-washer and tighten the nut a little.
Pull the ends of the strips to get a semetrical pattern and then tighten
the end-nut.
the flap wheel makes a flapping noise and some pieces will fly off
as the strips wear out. Apply no (that is NO) pressure, let the flapper
do the work. There is nothing magical about
the original diameter of the wheel, if it does what you want keep using
the wheel until the sandpaper wears down to the shaft before replacing it.
Caution: I tried using multiple sanding
disks from a disk sander and they work but their edges will cut if you get too
close, even though you split them so they will flap.
